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 repolarization phase of the action potential, where voltage becomes more negative after the +30mV peak, is caused primarily by __________. The opening of voltage-gated K+ channels allows K+ ions to exit the cell, repolarizing the membrane. In other words, the exit of K+ ions makes the membrane potential more negative.
