Excitatory postsynaptic potential — In neuroscience, an excitatory postsynaptic potential (EPSP) is a temporary depolarization of postsynaptic membrane potential caused by the flow of positively charged ions into the postsynaptic cell. They are the opposite of inhibitory… … Wikipedia
potential — 1. Capable of doing or being, although not yet doing or being; possible, but not actual. 2. A state of tension in an electric source enabling it to do work under suitable conditions; in relation to electricity, p. is analogous to the temperature… … Medical dictionary
Excitatory synapse — An excitatory synapse is a synapse in which an action potential in the presynaptic cell increases the probability of an action potential occurring in the postsynaptic cell (see also: EPSP)). At an excitatory synapse , the neurotransmitter opens… … Wikipedia

excitatory postsynaptic potential — (EPSP) a transient decrease in membrane polarization induced in a postsynaptic neuron when subjected to a volley of impulses over an excitatory afferent pathway; summation of such potentials may cause discharge by the neuron … Medical dictionary

Action potential — In physiology, an action potential is a short lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in several types of animal cells, called… … Wikipedia
Postsynaptic potential — Postsynaptic potentials are changes in the membrane potential of the postsynaptic terminal of a chemical synapse. Postsynaptic potentials are graded potentials, and should not be confused with action potentials although their function is to… … Wikipedia
Inhibitory postsynaptic 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… … Wikipedia
Membrane potential — Differences in concentration of ions on opposite sides of a cellular membrane lead to a voltage called the membrane potential. Many ions have a concentration gradient across the membrane, including potassium (K+), which is at a high inside and a… … Wikipedia
