Temporal summation is a response to the: Group of answer choices amount of neurotransmitter released from a presynaptic cell. location of synapses over the surface of a postsynaptic neuron. density of ligand-gated channels on the postsynaptic cell. frequency of stimulation of a postsynaptic cell.

A neurotransmitter can possibly work successfully if there is some approach to "turn off" the sign once it's been sent. End of the sign lets the postsynaptic cell come back to its ordinary resting potential, prepared for new motions toward show up.
The particles of synapses diffuse over the synaptic split and tie to receptor proteins on the postsynaptic cell. Initiation of postsynaptic receptors prompts the opening or shutting of particle directs in the cell film. This might be depolarizing make within the cell progressively positive or hyper polarizing make within the cell increasingly negative—depending upon the particles involved .
Hence, the right answer is "frequency of stimulation of a postsynaptic cell"
