Answer:
a. True
Step-by-step explanation:
Summation -
The process of summation includes both temporal and spatial summation .
The process of summation helps to determine whether or not an action potential would be generated by the inhibitory and excitatory signals .
Both , in the spatial summation , i.e. , multiple simultaneous inputs and
the temporal summation , i.e. , repeated inputs .
Now, by the sum of all the total individual inputs , summation could or could not reach to the threshold voltage in order to trigger the action potential .
