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.
Bernard Katz pioneered the study of these mEPSPs at the neuromuscular junction (often called miniature end-plate potentials [6]) in 1951, revealing the quantal nature of synaptic transmission. Quantal size can then be defined as the synaptic response to the release of neurotransmitter from a single vesicle, while quantal content is the number ...
Holonomic brain theory is a branch of neuroscience investigating the idea that consciousness is formed by quantum effects in or between brain cells. Holonomic refers to representations in a Hilbert phase space defined by both spectral and space-time coordinates. [1]
Summation may also refer to: Addition; Summation (neurophysiology), a way of achieving action potential in a neuron; In law, a closing argument; See also.
The cell size contribution to recruitment in motor neurons during postnatal development is investigated in this experiment. Experiments were done on 1- to 7-day-old Wistar rats and 20- to 30-day-old Wistar rats as well. The 1- to 7-day-old Wistar rats were selected because early after birth, the rats show an increase in cell size.
The uniqueness and the zeros of trigonometric series was an active area of research in 19th century Europe. First, Georg Cantor proved that if a trigonometric series is convergent to a function on the interval [,], which is identically zero, or more generally, is nonzero on at most finitely many points, then the coefficients of the series are all zero.
A generalized Fourier series is the expansion of a square integrable function into a sum of square integrable orthogonal basis functions.The standard Fourier series uses an orthonormal basis of trigonometric functions, and the series expansion is applied to periodic functions.
In mathematical analysis, Cesàro summation (also known as the Cesàro mean [1] [2] or Cesàro limit [3]) assigns values to some infinite sums that are not necessarily convergent in the usual sense. The Cesàro sum is defined as the limit, as n tends to infinity, of the sequence of arithmetic means of the first n partial sums of the series.
