What Does PSD Stand For?

PSD stands for Postsynaptic Density

Postsynaptic Density (PSD) refers to a specialized structure located at the postsynaptic membrane of excitatory synapses in neurons. It serves as a critical site for cellular signaling and the organization of receptors, scaffolding proteins, and various signaling molecules. The PSD plays a vital role in synaptic transmission, plasticity, and the overall functioning of neural circuits, influencing learning and memory processes. Its complex composition and dynamic nature are essential for regulating synaptic strength and facilitating communication between neurons.
