|
Occurs in the axon hillock.

|
|
During transmission, the charge may decrease.
|
|
|
When the charge becomes more negative or positive.
|
|
|
The membrane charge has changed but has not reached the threshold value.
|
Explanation:
Detailed explanation-1: -The amplitude of the EPSP is directly proportional to the number of synaptic vesicles that were released. If the EPSP is not large enough to trigger an action potential, the membrane subsequently repolarizes to its resting membrane potential.
Detailed explanation-2: -The threshold is the value of the membrane potential which, if reached, leads to the all-or-nothing initiation of an action potential. The initial or rising phase of the action potential is called the depolarizing phase or the upstroke.
