23. Neurotransmitter binding to the post-synaptic membrane, opening of potassium and/or chloride channels, resulting in hyperpolarization of the post-synaptic membrane:T a) is called an excitatory post-synaptic potential (ÉPSP) T + b) is called and inhibitory post-synaptic potential (IPSP).T + c) results in generation of an action potential in the post-synaptic membrane. T + d). results in one level of membrane depolarization regardless of the amount of - neurotransmitter released. T 24. Which of the following statements is correct with regard to integration and modification of- synaptic events. T a) - Very rapid transmission of impulses from the presynaptic neuron induces temporal summation that results in greater depolarization of the postsynaptic membrane if the stimuli are EPSPS. - b) Stimulation of the post-synaptic neuron by large numbers of presynaptic terminals induces spatial summation which also enhances depolarization. T + ) IPSPS can also show temporal and spatial summation which result in enhanced hyperpolarization of the post-synaptic membrane. T + dj Repeated stimulation of the presynaptic neuron produces postsynaptic potential changes that are larger than predicted by the strength of the stimulus-a phenomonon called synaptic potentiation. T + e) All of the above (a, b, c and d) are correct. T
