GABAA receptor
The GABA_A receptor is a protein found in the brain that helps regulate neural activity by responding to a chemical called gamma-aminobutyric acid (GABA). When GABA binds to this receptor, it opens a channel allowing negatively charged ions to enter brain cells, making it less likely for the cells to send signals. This process produces a calming effect, reducing anxiety, promoting sleep, and preventing excessive neural activity. The GABA_A receptor is a primary target for many medications used to treat anxiety, insomnia, and seizures by enhancing its calming action.
