This is substantially different from serotonergic psychedelics, with which brainwave patterns generally show a desynchronization. Electroencephalography (EEG) is a method of measuring brainwave activity non-invasively. He built a machine to relieve dental pain, using electric brainwave stimulation. Brain control interfaces (BCI) respond to the user's brainwave activity. Ashworth is a patron of Brainwave, which supports children with brain illnesses. Grey discovered that this stimulated similar brainwave activity. "Hemi-Sync" is short for "Hemispheric Synchronization", also known as "brainwave synchronization". "Hemi-Sync" is short for "Hemispheric Synchronization," also known as "brainwave synchronization". In 2010, a study provided some evidence of neuroplastic changes occurring after brainwave training. In 1937, he discovered the sleep K-complex brainwave. Srivalli is a movie about neuroscientist Srivalli who does an experiment about brainwave simulation.
