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.
Nongated ion channels establish the resting membranepotential of neurons; voltage-gated ion channels are re-sponsible for the action potential and the release of neuro-transmitter.2. Ligand-gated ion channels cause membrane depolariza-tion or hyperpolarization in response to neurotransmit-ter.3.
