The âline of actual controlâ between China and India in Arunachal Pradesh, which the Chinese refer to as South Tibet, is not as tense as the one in Kashmir. Talks between the two countries aimed at resolving the border issue have been going on for ten years and 15 rounds.
An excitatory postsynaptic potential, a type of graded potential, occurs because of the influx of Na+ through chemically gated channels in the receptive region, or postsynaptiâ¦c membrane, of a neuron.
The action potential occurs as a result of a stimulus to the neuron This means that some event (a stimulus) causes the resting potential to move toward 0 mV When a neuron is not sending a signal, it is at rest..hen a neuron is at rest, the inside of the neuron is negative relative to the outside Action potentials are caused by an exchange of ions across the neuron membrane. A stimulus first causes sodium channels to open.
