If a post synaptic cell is stimulated to threshold by temporal summation this implies that ________. a presynaptic neuron is sending frequent epsp the presynaptic neuron is sending frequent ipsp the postsynaptic cell is sending frequent action potential the postsynaptic cell can be influenced by only one presynaptic cell

The answer is presynaptic neuron is sending frequent epsp (excitatory postsynaptic potential). This temporary depolarization of postsynaptic membrane potential is caused by the flow of positively charged ions into the postsynaptic cell, as a result of opening ligand-gated ion channels. Accumulation of these EPSPs add up to the threshold of the post-synaptic neurons’ threshold to fire. The attached picture illustrates this.

If a postsynaptic cell is stimulated to threshold by temporal summation this implies that a presynaptic neuron is sending frequent epsp (excitatory postsynaptic potential).

What do you mean by Postsynaptic cell?

A postsynaptic cell may be defined as a cell that receives a signal from the presynaptic cell and responds via depolarisation or hyperpolarisation. These cells are bound with neurotransmitters.

This activity is mediated by positive ions like Na+ and K+. The efflux and influx of such ions lead to the hyperpolarization and depolarisation of the postsynaptic cell. The complete process of this activity is also known as all or none action potential.

Therefore, if a postsynaptic cell is stimulated to threshold by temporal summation this implies that a presynaptic neuron is sending frequent epsp.
