A microelectrode delivers a current pulse that depolarizes thepresynaptic terminal above threshold. Describe the events thatoccur (in molecular detail) immediately after depolarization. Youranswer should finish with the response of the postsynaptic neuron.The presynaptic neuron releases ACh and the postsynaptic neuron hasionotropic AChR.
what channels are activated in terminal?
what currents flows through the membrane? What direction?Why?
what are all the proteins involved in the release of AChvesicles?
mechanism?
