glutamate hypothesis

the theory that decreased activity of the excitatory neurotransmitter glutamate is responsible for the clinical expression of schizophrenia. The hypothesis, supported by a number of studies, developed from observations that administration of NMDA receptor antagonists, such as PCP (phencyclidine) and ketamine, produce psychotic symptoms in humans. See also dopamine hypothesis.

data analysis

the process of applying graphical, statistical, or quantitative techniques to a set of observations or measurements in order to summarize it or to find general patterns.
