The Hour of Code started as a one-hour introduction to computer science, designed to demystify code, to show that anybody can learn the basics, and to broaden participation in the field of computer science.
Definition. Protein characteristic of the postsynaptic membrane. In a chemical synapse, the postsynaptic membrane is the membrane that receives a signal (binds neurotransmitter) from the presynaptic cell and responds via depolarisation or hyperpolarisation. The postsynaptic membrane is separated from the presynaptic membrane by the synaptic cleft.
In neuroscience, an excitatory postsynaptic potential is a postsynaptic potential that makes the postsynaptic neuron more likely to fire an action potential. This temporary depolarization of postsynaptic membrane potential, caused by the flow of positively charged ions into the postsynaptic cell, is a result of opening ligand-gated ion channels. These are the opposite of inhibitory postsynaptic potentials, which usually result from the flow of negative ions into the cell or positive ions out of
