N-methyl-D-aspartate (NMDA) Receptor

The NMDA receptor is a specialized protein found on nerve cells in the brain that plays a key role in learning and memory. It acts like a gate that opens when certain chemicals, like glutamate, attach to it and when the cell is also depolarized. This allows calcium and other ions to flow into the cell, strengthening connections between neurons. Proper NMDA receptor function is essential for healthy brain signaling, but overactivity or underactivity can be linked to neurological issues. In summary, the NMDA receptor is crucial for brain plasticity and effective communication between nerve cells.
