inhibitory post-synaptic potential

initialism: IPSP
https://doi.org/10.1351/goldbook.11832
Referring to a more negative membrane potential at the postsynaptic side of the synaptic cleft that renders the postsynaptic neuron less likely to generate an action potential.
Notes:
  1. IPSPs are commonly produced by inhibitory neurotransmitters such as γ-aminobutyric acid (GABA) and glycine.
  2. Postsynaptic electrical activity is in part a function of the balance of IPSPs and excitatory post-synaptic potentials (EPSPs).
