A high-fat diet decreases GABA concentration in the frontal cortex and hippocampus of rats
BACKGROUND: It has been proposed that the γ-aminobutyric acid (GABA) plays a key role in the regulation of food intake and body weight by controlling the excitability, plasticity and the synchronization of neuronal activity in the frontal cortex (FC). It has been also proposed that the high...
