Inhibitory neurons are a type of nerve cell that play a crucial role in regulating brain activity. They release neurotransmitters, such as GABA (gamma-aminobutyric acid), which help to decrease the likelihood of other neurons firing. This inhibition is essential for maintaining balance in the brain, preventing excessive excitability that can lead to conditions like epilepsy. These neurons are found throughout the central nervous system and are vital for processes such as learning, memory, and mood regulation. By controlling the flow of information between neurons, inhibitory neurons help to create a stable environment for proper brain function and overall cognitive health.
