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.
Postsynaptic Mechanisms of Chemical Transmission. After a chemical transmitter is released into the synaptic cleft, it can bind to a receptor located on the postsynaptic cell. The coupling of the transmitter with the receptor causes the receptor to open, permitting the passage of specific ions through the membrane.
