Noun
EPSP (plural EPSPs)
(neuroscience) Initialism of excitatory postsynaptic potential.
Although a single EPSP was not enough to fire an action potential in the motor neuron, the sum of several EPSPs from multiple sensory neurons synapsing onto the motor neuron could cause the motor neuron to fire, thus contracting the quadriceps. Source: Internet
If an IPSP overlaps with an EPSP, the IPSP can in many cases prevent the neuron from firing an action potential. Source: Internet
In many cases the excitatory postsynaptic potential (EPSP) will not reach the threshold for eliciting an action potential. Source: Internet
