A postsynaptic change in membrane potential that tends to prevent firing of an action potential in the postsynaptic cell, by bringing the membrane potential away from the threshold potential.
An electrical charge (hyperpolarisation) in the membrane of a postsynaptic neuron caused by the binding of an inhibitory neurotransmitter from a presynaptic cell to a postsynaptic receptor; makes it more difficult for a postsynaptic neuron to generate an action potential.
Graded hyperpolarization induced by neurotransmitter beneath synaptic junction of a neurone. Has inhibitory action on generation of impulses. Integrated with effects of EPSPs. Compare excitatory postsynaptic potential.
A hyperpolarization of the postsynaptic membrane after the arrival of a neurotransmitter.
is the hyperpolarisation of a postsynaptic membrane in response to a synaptic input which decreases the probability that a cell will fire an action potential
A change in the resting potential of a postsynaptic membrane in the hyperpolarizing (negative) direction.
a change in the transmembrane potential of a postsynaptic cell that reduces the probability of producing an action potential
An Inhibitory Postsynaptic Potential (commonly abbreviated as IPSP) is the change in membrane voltage of a postsynaptic neuron which results from synaptic activation of inhibitory neurotransmitter receptors. The most common inhibitory neurotransmitters in the nervous system are GABA and glycine.
