• Synapse — The point of connection usually between two nerve cells. Specifically, a synapse is a specialized junction at which a nerve cell (a neuron) communicates with a target cell. The neuron releases a chemical transmitter (a neurotransmitter) that… …   Medical dictionary

• Silent synapse — In neuroscience, a silent synapse is an excitatory glutamatergic synapse whose postsynaptic membrane contains NMDA type glutamate receptors but no AMPA type glutamate receptors. These synapses are so named because normal AMPA receptor mediated… …   Wikipedia

• Electrical synapse — An electrical synapse is a mechanical and electrically conductive link between two abutting neuron cells that is formed at a narrow gap between the pre and postsynaptic cells known as a gap junction. At gap junctions, such cells approach within… …   Wikipedia

• 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

• 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

• Long-term potentiation — (LTP) is a persistent increase in synaptic strength following high frequency stimulation of a chemical synapse. Studies of LTP are often carried out in slices of the hippocampus, an important organ for learning and memory. In such studies,… …   Wikipedia

• Nonsynaptic plasticity — Brain connectivity network Nonsynaptic plasticity is a form of neuroplasticity that involves modification of ion channel function in the axon, dendrites, and cell body that results in specific changes in the integration of EPSPs and IPSPs, thus… …   Wikipedia
