GABAközvetített

GABAközvetített is a Hungarian term that translates to "GABA-mediated" in English. It refers to biological processes that are influenced or regulated by gamma-aminobutyric acid (GABA). GABA is the principal inhibitory neurotransmitter in the central nervous system of mammals. It plays a crucial role in reducing neuronal excitability throughout the nervous system.

When GABA binds to its receptors on a neuron, it typically causes an influx of chloride ions into the cell. This influx hyperpolarizes the neuron, making it less likely to fire an action potential. This inhibitory action is essential for maintaining a balance between excitation and inhibition in the brain, which is vital for a wide range of functions including motor control, cognition, and mood regulation.

Therefore, any process described as GABAközvetített is one where GABA's inhibitory signaling is the primary mechanism of action. This can include the effects of certain drugs, the modulation of neural circuits involved in learning and memory, or the regulation of sleep-wake cycles. Understanding GABAközvetített processes is fundamental to neuroscience and pharmacology, as disruptions in GABAergic signaling are implicated in various neurological and psychiatric disorders such as epilepsy, anxiety disorders, and insomnia. Research into GABAközvetített pathways continues to be a significant area of study for developing new therapeutic interventions.
