Functional Aspects of Cholinergic Neurotransmission

In neuroscience, an excitatory postsynaptic potential (EPSP) is a postsynaptic potential that makes the postsynaptic neuron more likely to fire an action potential. This temporary depolarization of postsynaptic membrane potential, caused by the flow of positively charged ions into the postsynaptic cell, is a … Visa mer The neurotransmitter most often associated with EPSPs is the amino acid glutamate, and is the main excitatory neurotransmitter in the central nervous system of vertebrates. Its ubiquity at excitatory synapses … Visa mer The release of neurotransmitter vesicles from the presynaptic cell is probabilistic.

WebbWhen evoked at membrane potentials between ‐20 and ‐55 mV after blockade of outward K+ currents and fast Na+ spikes by intracellular injection of Cs+ and QX‐314 (n = 5 neurons), a slow depolarizing potential emerged near the fast peak of the EPSP. This slow potential, unlike the fast peak, was not linearly related to membrane potential. 3. Webbthe fast and slow EPSPs in these neurons. Subthreshold fast EPSPs evoked spikes dur-ing the rising phase of a slow EPSP, but suprathreshold fast EPSPs could not evoke spikes later in a slow EPSP. This predicted inhibition was confirmed by Ca2+ imaging in which stimuli that evoke slow EPSPs suppressed activity evoked by fast EPSPs in many
