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.
An excitatory potential causes positively charged ions to enter the neuron. The neuron is then said to be âdepolarized,â because its membrane potential is less negative than its resting potential (which is about -70 mV).he neuron is then said to be âdepolarized,â because its membrane potential is less negative than its resting potential (which is about -70 mV).
