      In neuroscience, an excitatory postsynaptic potential (EPSP) is a postsynaptic potential that makes the neuron more likely to fire an action potential. This temporary depolarization of postsynaptic membrane potential, caused by the flow of positively char

An inhibitory postsynaptic potential (IPSP) is a kind of synaptic potential that makes a postsynaptic neuron less likely to generate an action potential.[1] The opposite of an inhibitory postsynaptic potential is an excitatory postsynaptic potential (EPSP...

This video demonstrates the development of myelin in the peripheral nervous system and the propagation of action potential along a myelinated axon. The video was completed by Marziah Karch as her 2008 sabbatical project from the script and voiceover of Pr...

It is believed that transmission from one cell to another at a synapse like the one just described (a chemical synapse, as opposed to an electrical synapse) is accomplished by release of a substance, the transmitter substance, from the synaptic vesicles i...

Temporal summation. A single action potential in sensory neuron 1 produces a 1-mV EPSP in the motor neuron. Now consider the consequences of firing two action potentials in quick succession (See figure above). Two EPPs are elicited, the second of which .....

Remember how generating an AP is like pushing a boulder over a cliff to get it over the threshold? With EPSP’s and IPSP’s we have people (excitatory NT’s) pushing the boulder uphill, trying to push it over trying to generate a AP and we also have others (...

Data were analysed offline using Igor Pro (Wavemetrics, Lake Oswego, OR, USA). EPSP integrals were calculated from the stimulus artifact until the voltage stably relaxed to baseline. Undershooting phases contributed negatively and thus reduced the total i...

Ch.5: Synaptic Activity Introduction Otto Loewi studied the heart of the frog, which-like our own hearts- is supplied by two different peripheral nerves. One, the sympathetic nerve, excites the heart and makes it beat more rapidly; the other , the vagus, ...
