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 result of … See more 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 … See more The release of neurotransmitter vesicles from the presynaptic cell is probabilistic. In fact, even without stimulation of the presynaptic cell, a single vesicle will occasionally be released into the synapse, generating miniature EPSPs (mEPSPs). Bernard Katz pioneered … See more • Quantal transmission at neuromuscular synapses See more EPSPs are usually recorded using intracellular electrodes. The extracellular signal from a single neuron is extremely small and thus next to impossible to record in the human brain. … See more • Glycine • Nonspiking neurons • Summation (neurophysiology) See more WebFeedforward and recurrent inhibitory receptive fields of principal cells in the cat’s dorsal lateral geniculate nucleus

WebThus, EPSPS is the main target of various herbicides, including glyphosate, a broad-spectrum herbicide that acts as a competitive inhibitor of phosphoenolpyruvate (PEP), which is the natural substrate of EPSPS. However, punctual mutations in the EPSPS gene have led to glyphosate resistance in some plants. WebEPSPs are amplified by persistent sodium ion conductance in external tufted cells. Low-voltage activated calcium ion conductance enhances even larger EPSPs. The …
