inhibitory potential

• inhibitory postsynaptic potential — n increased negativity of the membrane potential of a neuron on the postsynaptic side of a nerve synapse that is caused by a neurotransmitter (as gamma aminobutyric acid) which renders the membrane selectively permeable to potassium and chloride… …   Medical dictionary

• 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

• 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

• inhibitory synapse — A synapse in which an action potential in the presynaptic cell reduces the probability of an action potential occurring in the postsynaptic cell. The most common inhibitory neurotransmitter is GABA; this opens channels in the postsynaptic cell… …   Dictionary of molecular biology

• 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

• 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

• 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
