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.
During an action potential, ions cross back and forth across the neuronâs membrane, causing electrical changes that transmit the nerve impulse: The stimulus causes sodium channels in the neuronâs membrane to open, allowing the Na + ions that were outside the membrane to rush into the cell.
