Inhibitory neurotransmitters are chemicals in the brain that help reduce the activity of neurons. They play a crucial role in balancing brain function by preventing excessive firing of nerve cells, which can lead to anxiety, seizures, or other neurological issues. Common inhibitory neurotransmitters include gamma-aminobutyric acid (GABA) and glycine. These neurotransmitters bind to specific receptors on neurons, causing them to become less likely to fire. This process is essential for maintaining a stable and healthy nervous system, allowing for proper communication between neurons and helping to regulate mood, sleep, and overall brain activity.
