Q

explain how synaptic plasticity works

A

AMPA R responsible for basal Na+ influx and synaptic transmission

however, when there’s high activation/depolarization, Mg2+ on NMDA R leaves, so now the NMDA R opens up to allow Ca2+ influx to postsynpatic neuron. Ca2+ activates CaMKII to bring AMPA R in postsy neur to the synapse

Q

Long term potentiation

A

an induction used so that when the same presynaptic stimulus occurs, it results in higher reponses for a longer time compared to baseline synaptic transmission
