Detailed explanation-1: -Gamma-aminobutyric acid (GABA) is an amino acid that functions as the primary inhibitory neurotransmitter for the central nervous system (CNS). It functions to reduce neuronal excitability by inhibiting nerve transmission.
Detailed explanation-2: -GABA is the principal inhibitory neurotransmitter in the CNS and is opposed by the excitatory neurotransmitter glutamate.
Detailed explanation-3: -Regarding control of striatal dopamine, recent studies suggest that tonic GABA inhibits dopamine release primarily through activation of GABA-B receptors, with little to no contribution of GABA-A receptors in this process (Brodnik et al., 2019; Lopes et al., 2019).
Detailed explanation-4: -A high-fat diet decreases GABA levels in the frontal cortex and hippocampus.
