Gaba and glutamate in schizophrenia
WebGlutamatergic models are based upon the observation that the psychotomimetic agents such as phencyclidine (PCP) and ketamine induce psychotic symptoms and neurocognitive disturbances similar to those of schizophrenia by blocking neurotransmission at N-methyl-D-aspartate (NMDA)-type glutamate receptors. WebGABA and glutamate act like an “on” and “off” switch. They work in opposite ways. GABA is the main inhibitory neurotransmitter in your brain, stopping the chemical messages from passing from nerve cell to nerve cell.

WebInhibition of the NMDA (glutamate) receptor enhances the firing rate of dopamine neurons, and in turn results in more psychosis. Glutamate is also a precursor to GABA production. GABA has an inverse relationship with dopamine, so the less GABA there is, the more dopamine and more psychosis.
