Webb20 okt. 2024 · At least two theories exist for how inhibition may acutely decrease during a seizure: hyperpolarization of fast-spiking (FS) inhibitory neurons by other inhibitory neurons, or depolarization block (DB) of FS neurons resulting in an inability to fire action potentials. Firing rate alone is unable to disambiguate these alternatives. WebbGamma-aminobutyric acid (GABA) is the most common inhibitory neurotransmitter in your central nervous system. GABA lessens the ability of a nerve cell to receive, create or send chemical messages to other nerve cells. GABA is known for producing a calming effect. It’s thought to play a major role in controlling anxiety, stress and fear.
