After binding a neurotransmitter packet of 1000 to 10,000 molecules, post-synaptic membrane changes 1 mV to 15 mV {post-synaptic potential} (PSP), with average of 10 mV, lasting 10 to 100 milliseconds. Initial change is rapid, and decay is slow. Potential change affects membrane up to two millimeters away. Spontaneous neurotransmitter release makes changes of 0.5 mV, lasting 20 milliseconds. Miniature end plate potentials depolarize synapse by 0.7 mV, lasting 10 milliseconds. Frequency is directly proportional to membrane depolarization. Frequency is five per second at membrane resting voltage.
