It is defined precisely as a chemical junction where the arrival of an action potential at the presynaptic […]

Introduction to Synaptic Depression Synaptic depression refers fundamentally to a transient or sustained reduction in the efficacy of communication across a synapse, resulting in a diminished ability for the presynaptic neuron to excite the postsynaptic target. This physiological phenomenon stands as a critical and ubiquitous mechanism of neural plasticity, defining the constantly adaptable nature of […]
