Inhibitory Neurotransmitters

Meaning

Inhibitory Neurotransmitters are chemical messengers in the central nervous system that function to decrease the likelihood of a neuron firing an action potential, essentially promoting calming and rest in the brain. These crucial molecules counteract the effects of excitatory neurotransmitters, maintaining a necessary balance in neural activity. Gamma-Aminobutyric Acid (GABA) is the most prominent example, playing a central role in anxiety regulation, muscle relaxation, and the initiation of sleep. Deficiencies or dysfunctions in these systems are often implicated in states of chronic stress, insomnia, and heightened anxiety. Optimizing their function is key to neurological resilience.
