Answer:
Temporal summation is a response to the frequency of stimulation of a postsynaptic cell.
Explanation:
Summation is understood to mean the calculation of nerve impulses arriving in the nerve cell, which can either have an excitatory or an inhibitory effect on the development of an action potential. It can be either spatial or temporal.
In temporal summation, if several excitatory or inhibitory potentials occur in the neuron from a single synapse in sufficiently short time intervals, these are also summed up and if a certain threshold value is exceeded, an action potential arises at the axon hill.
Answer:
frequency of stimulation of a postsynaptic cell.
Explanation:
Summation is a mechanism in neurophysiology that determines if action potential will be generated or not. It involves multiple input from two types of summation which includes:
- spatial summation and,
- temporal summation.
TEMPORAL SUMMATION occurs when a single presynaptic neurone releases neurotransmitters many times over a period of time which causes the post-synaptic neuron to reach its threshold while,
- SPATIAL SUMMATION occurs when excitatory potentials from many different pre-synaptic neurons cause the post-synaptic neuron to reach its threshold.
