Query: How do you become a neuroscientist?
The scientific study of the nervous system increased significantly during the second half of the twentieth century, principally due to advances in molecular biology, electrophysiology, and computational neuroscience. This has allowed neuroscientists to study the nervous system in all its aspects: how it is structured, how it works, how it develops, how it malfunctions, and how it can be changed. For example, it has become possible to understand, in much detail, the complex processes occurring within a single neuron. Neurons are cells specialized for communication. They are able to communicate with neurons and other cell types through specialized junctions called synapses, at which electrical or electrochemical signals can be transmitted from one cell to another. Many neurons extrude a long thin filament of axoplasm called an axon, which may extend to distant parts of the body and are capable of rapidly carrying electrical signals, influencing the activity of other neurons, muscles, or glands at their termination points. A nervous system emerges from the assemblage of neurons that are connected to each other.
Today, in the U.S., about half of licensed psychologists are trained in the Scientist-Practitioner Model of Clinical Psychology (PhD)—a model that emphasizes both research and clinical practice and is usually housed in universities. The other half are being trained within a Practitioner-Scholar Model of Clinical Psychology (PsyD), which focuses on practice (similar to professional degrees for medicine and law). A third training model called the Clinical Scientist Model emphasizes training in clinical psychology research. Outside of coursework, graduates of both programs generally are required to have had 2 to 3 years of supervised clinical experience, a certain amount of personal psychotherapy, and the completion of a dissertation (PhD programs usually require original quantitative empirical research, whereas the PsyD equivalent of dissertation research often consists of literature review and qualitative research, theoretical scholarship, program evaluation or development, critical literature analysis, or clinical application and analysis).
The term "cognitive science" was coined by Christopher Longuet-Higgins in his 1973 commentary on the Lighthill report, which concerned the then-current state of Artificial Intelligence research. In the same decade, the journal "Cognitive Science" and the Cognitive Science Society were founded. The founding meeting of the Cognitive Science Society was held at the University of California, San Diego in 1979, which resulted in cognitive science becoming an internationally visible enterprise. In 1972, Hampshire College started the first undergraduate education program in Cognitive Science, led by Neil Stillings. In 1982, with assistance from Professor Stillings, Vassar College became the first institution in the world to grant an undergraduate degree in Cognitive Science. In 1986, the first Cognitive Science Department in the world was founded at the University of California, San Diego.
The PhD Program is aimed to prepare highly qualified researchers holding a candidate of science degree (equivalent of PhD). Training is provided through 142 specialities of different branches of science. Duration of studies is 3-4 academic years. Classes last from 1 November until 31 October. International students have the opportunity to study according to the individual curriculum without a fixed dates enrollment. Upon successful completion graduates receive a Certificate on Graduation and in case if dissertation was presented and defended the student confers the Candidate if Science degree. The BSU has 22 Scientific Councils which conduct evaluations of theses presented for defence.
Findings reported in published studies of Tourette syndrome since 1999 have advanced TS science in the areas of genetics, neuroimaging, neurophysiology, and neuropathology. The TAA supports a clinical database that may help identify genes involved in Tourette syndrome, and the TSA International Genetic Consortium has collected a database on large extended families for future studies. Novel neuroimaging studies are being employed to study tic expression and functional or cognitive deficits in TS patients. Studies of Tourette's neurophysiology and neuropathology are attempting to link deficits in Tourette's to specific brain mechanisms, and have taken advantage of a brain bank sponsored by the TSA. Clinical trials have focused on understanding tic suppression, comorbid conditions, novel treatment approaches such as botulinum toxin, and targeted behavioral therapies. Controversy remains in the areas of deep brain stimulation and PANDAS.
Due to more recent Medical, Rehabilitation and ongoing results 'neuroplasticity' within the mechanics of our brains lead to re-arrangement of the brain's workings. These often result in the synapses arranging alternate routes, to achieve previous habits. Neuroplasticity is the brain's ability to reorganise itself by forming new neural connections throughout life. Neuroplasticity allows the neurons (nerve cells) in the brain to compensate for injury and disease and to adjust their activities in response to new situations or to changes in their environment.
The neuroscientist Donald Hebb (1904–1985) was the first to distinguish between short-term memory and long-term memory. According to current theories in neuroscience, things that we "notice" are stored in short-term memory for up to a few minutes; this memory depends on "reverberating" electrical activity in neuronal circuits, and is very easily destroyed by interruption or interference. Memories stored for longer than this are stored in "long-term memory". Whether information is stored in long-term memory depends on its "importance"; for any animal, memories of traumatic events are potentially important for the adaptive value that they have for future avoidance behavior, and hormones that are released during stress have a role in determining what memories are preserved. In humans, traumatic stress is associated with acute secretion of epinephrine and norepinephrine (adrenaline and noradrenaline) from the adrenal medulla and cortisol from the adrenal cortex. Increases in these facilitate memory, but chronic stress associated with prolonged hypersecretion of cortisol may have the opposite effect. The limbic system is involved in memory storage and retrieval as well as giving emotional significance to sensory inputs. Within the limbic system, the hippocampus is important for explicit memory, and for memory consolidation; it is also sensitive to stress hormones, and has a role in recording the emotions of a stressful event. The amygdala may be particularly important in assigning emotional values to sensory inputs.
While the scientist-practitioner model “stood intransigent and impervious through the 1950s and 60s”, the APA attempted to respond to pressure for more and better clinical training by forming the Committee on the Scientific and Professional Aims of Psychology in 1963. The Committee concluded that the scientist-practitioner model failed to do either of the jobs for which it was designed and recommended several important changes, including: establishing separate practice-oriented programs, potentially in locations other than university psychology departments; developing a practice-oriented training model; and using the Doctor of Psychology (PsyD) degree to designate preparation for clinical practice. The Committee's conclusions and recommendations met with controversy. In particular, opponents said a different degree would impact the field's prestige and ignore science. Proponents, however, argued it would be informed by science and that other practice-oriented healthcare disciplines, such as medicine, had well-respected professional degrees.
Cultural neuroscience is a field of research that focuses on the interrelation between a human’s cultural environment and neurobiological systems. The field particularly incorporates ideas and perspectives from related domains like anthropology, psychology, and cognitive neuroscience to study sociocultural influences on human behaviors . Such impacts on behavior are often measured using various neuroimaging methods, through which cross-cultural variability in neural activity can be examined.
The founding father of the independent Psychology major, available from the turn of the millennium, is Professor Csaba Pléh, member of the Hungarian Academy of Sciences, who organized the Cognitive Science Group at the Department of Psychology, and in 1999, started the Cognitive Science and Neuropsychology Program of Szeged, or in short, the Cognitive Program. He laid the foundation for a professional psychology training course at the University of Szeged. The university's Medical Faculty and the Cognitive Science Group, led by Csaba Pléh, organized the VIII. Conference of the Hungarian Cognitive Science Association (MAKOG), titled The Development and Disorders of Cognitive Functions for 4–6 February 2000 in Szeged.
A surprising consequence of neuroplasticity is that the brain activity associated with a given function can be transferred to a different location; this can result from normal experience and also occurs in the process of recovery from brain injury. Neuroplasticity is the fundamental issue that supports the scientific basis for treatment of acquired brain injury with goal-directed experiential therapeutic programs in the context of rehabilitation approaches to the functional consequences of the injury.
Neuroplasticity is defined as the brain's ability to reorganize itself, lay new pathways, and rearrange existing ones, as a result of experience. Neuronal changes after damage to the brain such as collateral sprouting, increased activation of the homologous areas, and map extension demonstrate the brain's neuroplastic abilities. According to Thomson, "Portions of the right hemisphere, extended left brain sites, or both have been shown to be recruited to perform language functions after brain damage. All of the neuronal changes recruit areas not originally or directly responsible for large portions of linguistic processing. Principles of neuroplasticity have been proven effective in neurorehabilitation after damage to the brain. These principles include: incorporating multiple modalities into treatment to create stronger neural connections, using stimuli that evoke positive emotion, linking concepts with simultaneous and related presentations, and finding the appropriate intensity and duration of treatment for each individual patient.
In 1882 Neisser was appointed professor extraordinarius by the University at the age of 29, and worked as a dermatologist in the university hospital of Breslau. Later he was promoted to the director of the hospital. In the following year he married Toni Neisser, née Kauffmann.
Thewissen’s current work involves counting neurons in bowhead and beluga whale brain samples, to assess brain function, in Utqiagvik—formerly Barrow—Alaska. Though the size of the brains of sperm whales and killer whales are larger than those of any other organism, including humans, a better measure of brain function is to determine how many neurons there are in the brain. Suzana Herculano-Houzel has developed a method of counting of neurons of human and other animals' brains and the relation between the cerebral cortex area and thickness and number of cortical folds. Humans and other primates pack about twice the number of neurons in a cubed inch of brain as most other mammals.
In an interview with Dr. Milton Stenn in 1977, Bowlby explained that his career started off in the medical direction as he was following in his surgeon father's footsteps. His father was a well-known surgeon in London and Bowlby explained that he was encouraged by his father to study medicine at Cambridge. Therefore, he followed his father's suggestion, but was not fully interested in anatomy and natural sciences that he was reading about. However, during his time at Trinity College, he became particularly interested in developmental psychology which led him to give up medicine by his third year. When Bowlby gave up medicine, he took a teaching opportunity at a school called Priory Gates for six months where he worked with maladjusted children. Bowlby explained that one of the reasons why he went to work at Priory Gates was because of an intelligent staff member, John Alford. Bowlby explained that the experience at Priory Gates was extremely influential on him "It suited me very well because I found it interesting. And when I was there, I learned everything that I have known; it was the most valuable six months of my life, really. It was analytically oriented". He further explained that the experience at Priory Gates was extremely influential to his career in research as he learned that the problems of today should be understood and dealt with at a developmental level.
Simply put: Cognitive Science is the interdisciplinary study of cognition in humans, animals, and machines. It encompasses the traditional disciplines of psychology, computer science, neuroscience, anthropology, linguistics and philosophy. The goal of cognitive science is to understand the principles of intelligence with the hope that this will lead to better comprehension of the mind and of learning and to develop intelligent devices.
The cognitive sciences began as an intellectual movement in the 1950s often referred to as the cognitive revolution.
The young doctor Ivan Pavlov wants to live life "honorably and humanely." The path of the scientist is difficult and thorny. The treasury department does not release funds for research nor give access to animals for experimental use and Pavlov has to buy them on his own savings. The experiments follow one another. Pavlov is pursuing his goal with passion and force. For his work on the physiology of digestion he is awarded the Nobel Prize. Pavlov paves the way for objective studies of brain function in higher animals. Zvantsev, the assistant of Pavlov is an idealist who has become an ideological opponent of the scientist-materialist, implores him not to interfere with the "sanctuary of the spirit", but Pavlov boldly ignores his opponents-obscurantists. The revolutionary 1917 year comes. Pavlov angrily rejects the proposal of an American agent to go abroad; he decides to forever remain with his people in his homeland.
By the end of the 20th century, it became clear that the human brain operates with more than a dozen neurotransmitters and a large number of neuropeptides and hormones. The relationships between these different chemical systems are complex as some of them suppress and some of them induce each other’s release during neuronal exchanges. This complexity of relationships devalues the old approach of assigning “inhibitory vs. excitatory” roles to neurotransmitters: the same neurotransmitters can be either inhibitory or excitatory depending on what system they interact with. It became clear that an impressive diversity of neurotransmitters and their receptors is necessary to meet a wide range of behavioural situations, but the links between temperament traits and specific neurotransmitters are still a matter of research. Several attempts were made to assign specific (single) neurotransmitters to specific (single) traits. For example, dopamine was proposed to be a neurotransmitter of the trait of Extraversion, noradrenaline was linked to anxiety, and serotonin was thought to be a neurotransmitter of an inhibition system. These assignments of neurotransmitter functions appeared to be an oversimplification when confronted by the evidence of much more diverse functionality. 
Research groups led by Petra Netter in Germany, Lars Farde in Karolinska Institute in Sweden and Trevor Robbins in Cambridge, UK had most extensive studies of the links between temperament/personality traits or dynamical properties of behavior and groups of neurotransmitters
Dopamine was first synthesized in 1910 by George Barger and James Ewens at Wellcome Laboratories in London, England and first identified in the human brain by Kathleen Montagu in 1957. It was named dopamine because it is a monoamine whose precursor in the Barger-Ewens synthesis is 3,4-dihydroxyphenylalanine (levodopa or L-DOPA). Dopamine's function as a neurotransmitter was first recognized in 1958 by Arvid Carlsson and Nils-Åke Hillarp at the Laboratory for Chemical Pharmacology of the National Heart Institute of Sweden. Carlsson was awarded the 2000 Nobel Prize in Physiology or Medicine for showing that dopamine is not only a precursor of norepinephrine (noradrenaline) and epinephrine (adrenaline), but is also itself a neurotransmitter.
Comparative psychology refers to the scientific study of the behavior and mental processes of non-human animals, especially as these relate to the phylogenetic history, adaptive significance, and development of behavior. Research in this area explores the behavior of many species, from insects to primates. It is closely related to other disciplines that study animal behavior such as ethology. Research in comparative psychology sometimes appears to shed light on human behavior, but some attempts to connect the two have been quite controversial, for example the Sociobiology of E.O. Wilson. Animal models are often used to study neural processes related to human behavior, e.g. in cognitive neuroscience.
Neisser was born in the Silesian town of Schweidnitz (now Świdnica, in Poland), the son of a well-known Jewish physician, Dr. Moritz Neisser. After he completed the elementary school in Münsterberg, Neisser enrolled in the St. Maria Magdalena School in Breslau (now Wrocław, in Poland). In this school, he was a contemporary of another great name in the history of medicine, Paul Ehrlich. He obtained the Abitur in 1872.
To become a clinical neuropsychologist in the UK, requires prior qualification as a clinical or educational psychologist as recognised by the Health Professions Council, followed by further postgraduate study in clinical neuropsychology. In its entirety, education to become a clinical neuropsychologist in the UK consists of the completion of a 3-year British Psychological Society accredited undergraduate degree in psychology, 3-year Doctorate in clinical (usually D.Clin.Psy.) or educational psychology (D.Ed.Psy.), followed by a 1-year Masters (MSc) or 9-month Postgraduate Diploma (PgDip) in Clinical Neuropsychology.
The British Psychological Division of Counselling Psychology are also currently offering training to its members in order to ensure that they can apply to be registered Neuropsychologists also.
The overall median salary for neuroscientists in the United States was $79,940 in May 2014. Neuroscientists are usually full-time employees. Below, median salaries for common work places in the United States are shown.
Neuroscientists research and study both the biological and psychological aspects of the nervous system. Once neuroscientists finish their post doctoral programs, 39% go on to perform more doctoral work, while 36% take on faculty jobs. Neuroscientists use a wide range of mathematical methods, computer programs, biochemical approaches and imaging techniques such as magnetic resonance imaging, computed tomography angiography, and diffusion tensor imaging. Imaging techniques allow scientists to observe physical changes in the brain, as signals occur. Neuroscientists can also be part of several different neuroscience where they can publish and read different research topics.
To become a clinical neuropsychologist in Australia requires the completion of a 3-year Australian Psychology Accreditation Council (APAC) approved undergraduate degree in psychology, a 1-year psychology honours, followed by a 2-year Masters or 3-year Doctorate of Psychology (D.Psych) in clinical neuropsychology. These courses involve coursework (lectures, tutorials, practicals etc.), supervised practice placements and the completion of a research thesis.
Masters and D.Psych courses involve the same amount of coursework units, but differ in the amount of supervised placements undertaken and length of research thesis. Masters courses require a minimum of 1,000 hours (125 days) and D.Psych courses require a minimum of 1,500 hours (200 days), it is mandatory that these placements expose students to acute neurology/neurosurgery, rehabilitation, psychiatric, geriatric and paediatric populations.
In order to become a clinical neuropsychologist in the US and be compliant with Houston Conference Guidelines, the completion of a 4-year undergraduate degree in psychology and a 4 to 5-year doctoral degree (Psy.D. or Ph.D.) must be completed. After the completion of the doctoral coursework, training and dissertation, students must complete a 1-year internship, followed by an additional 2 years of supervised residency. The doctoral degree, internship and residency must all be undertaken at American Psychological Association approved institutions.
After the completion of all training, students must apply to become licensed in their state to practice psychology. The American Board of Clinical Neuropsychology, The American Board of Professional Neuropsychology, and The American Board of Pediatric Neuropsychology all award board certification to neuropsychologists that demonstrate competency in specific areas of neuropsychology, by reviewing the neuropsychologist's training, experience, submitted case samples, and successfully completing both written and oral examinations. Although these requirements are standard according to Houston Conference Guidelines, even these guidelines have stated that the completion of all of these requirements is still aspirational, and other ways of achieving clinical neuropsychologist status are possible.
