GABAergic neurons are a type of nerve cell that primarily use the neurotransmitter gamma-aminobutyric acid (GABA) to communicate with other neurons. They play a crucial role in inhibiting or reducing the activity of neighboring neurons, helping to maintain a balance between excitation and inhibition in the brain. This balance is essential for normal brain function and helps prevent conditions like anxiety and seizures. These neurons are found throughout the central nervous system and are particularly abundant in areas such as the cerebral cortex and hippocampus. By regulating neuronal excitability, GABAergic neurons contribute to various processes, including learning, memory, and overall emotional stability.
