Q. What is function of Gamaaminobutyric acid?
GABA is the principal inhibitory transmitter in the brain. The concentration of GABA is up to 1000 times greater than that of other transmitters like acetylcholine or dopamine. Neurons containing GABA are relatively small, and widely distributed, especially in regions-cerebral cortex, striatum, hypothalamus, septum and thalamus.
Receptors
There are two types of GABA receptors: GABAA and GABAB.
