The dorsal striatum is located in the subcortical region of the forebrain. Projections stemming from the MRN modulate dopaminergic activity within the forebrain. Markers for forebrain and hindbrain can also be tested. Below and in front of the striatum are a number of basal forebrain structures. These differences are located in the ventral forebrain and the dopamine-mediated reward pathway. Dopamine tends to limit and select sensory information arriving from the thalamus to the forebrain. Regions include the lateral hypothalamus and medial forebrain bundles, which are especially effective. The developing forebrain surrounds the neural cord. Within the brain, galanin has also been found in the ventral forebrain and amygdala. This development is induced by the ventral part of the forebrain. Finally, the signals are received in cortex areas of the forebrain where thirst arises. It travels around the brain along the medial forebrain bundle and acts on serotonin receptors. The putamen is a structure in the forebrain. The pons releases acetylcholine which travels to parts of the forebrain. Blocking these receptors causes diminished neurotransmitter binding in the forebrain, resulting in many different effects.
