NEET PG DENTAL EXAM

Detailed explanation-1: -The reversal potential (Erev) for the postsynaptic current is approximately 0 mV, whereas the resting potential of neurons is approximately-60 mV. The resulting EPSP will depolarize the postsynaptic membrane potential, bringing it toward 0 mV.

Detailed explanation-2: -An example of excitatory postsynaptic potential (EPSP) is Glutamate. It is an excitatory neurotransmitter that occurs in vertebrates; especially in the central nervous system or CNS. The EPSPs function by the induction of neurotransmitter; this helps in the opening of calcium channels.

Detailed explanation-3: -Properties of EPSP EPSP is restricted to the synapse only. It typically increases the neurons’ membrane potential. Like IPSPs, EPSPs are graded (have an additive effect). The combined effect of multiple EPSPs on a single region of the postsynaptic membrane equals the sum of the individual EPSPs.
