An epsp (excitatory post synaptic potential) greater than threshold, will generate which of the following?
a) hyperpolarization of the post synaptic neuron
b) a graded potential in the post synaptic neuron
c) a muscle contraction at the mep
d) repolarization of the post synaptic neuron
e) an action potential in the post synaptic neuron

The correct answer will be option E- an action potential in the post synaptic neuron.

Explanation:

The excitatory postsynaptic potential or EPSP is the change in the membrane potential or voltage due to the opening of the sodium voltage-gated channels.

The opening of the Na⁺ voltage-gated channels leads to the influx of the Na⁺ ions inside the cells which causes the depolarization of the postsynaptic cells. This depolarization leads to the generation of the action potential in the cell which can be transmitted further.

Thus, option E is the correct option.
