Depending on the sum total of many individual inputs, summation may or may not reach the threshold voltage to trigger an action potential. [1] Neurotransmitters released from the terminals of a presynaptic neuron fall under one of two categories, depending on the ion channels gated or modulated by the neurotransmitter receptor.
Ptolemy's theorem states that the sum of the products of the lengths of opposite sides is equal to the product of the lengths of the diagonals. When those side-lengths are expressed in terms of the sin and cos values shown in the figure above, this yields the angle sum trigonometric identity for sine: sin(α + β) = sin α cos β + cos α sin β.
In neurophysiology, the Compound action potential (or CAP) refers to various evoked potentials representing the summation of synchronized individual action potentials generated by a group of neurons or muscle fibers in response to a stimulus. [1]
In mathematics, the Fejér kernel is a summability kernel used to express the effect of Cesàro summation on Fourier series. It is a non-negative kernel, giving rise to an approximate identity . It is named after the Hungarian mathematician Lipót Fejér (1880–1959).
In classic brain theory the summation of electrical inputs to the dendrites and soma (cell body) of a neuron either inhibit the neuron or excite it and set off an action potential down the axon to where it synapses with the next neuron. However, this fails to account for different varieties of synapses beyond the traditional axodendritic (axon ...
1. Not bringing your ingredients to room temperature. Before you preheat your oven or turn on your mixer, be sure that your ingredients are at room temperature, roughly 65° to 70°F. This is ...
A Maryland jury finds 'Real Housewives of Potomac' star Karen Huger guilty of driving under the influence and several other charges after she was arrested earlier this year.
The summation of these three EPSPs generates an action potential. In neuroscience , an excitatory postsynaptic potential ( EPSP ) is a postsynaptic potential that makes the postsynaptic neuron more likely to fire an action potential .
