Inhibitory neurons are a type of nerve cell that play a crucial role in regulating brain activity. They release neurotransmitters, such as gamma-aminobutyric acid (GABA), which help to dampen or inhibit the activity of other neurons. This process is essential for maintaining a balance between excitation and inhibition in the brain, preventing excessive neural firing that can lead to disorders. These neurons are vital for various brain functions, including learning, memory, and mood regulation. By controlling the flow of information between neurons, inhibitory neurons help to create a stable environment for cognitive processes and emotional responses, ensuring that the brain operates efficiently.
