post-synaptic density

The post-synaptic density is a specialized area located on the receiving side of a neuron (nerve cell) at a synapse, where two neurons communicate. It is a dense collection of proteins that help anchor neurotransmitter receptors and organize signaling molecules, ensuring efficient transmission of signals. This structure is essential for synaptic strength and plasticity, playing a key role in learning and memory. Essentially, it acts like a communication hub, organizing and stabilizing the elements needed for neurons to transmit signals precisely and effectively.
