  2. Summation (neurophysiology) - Wikipedia

    en.wikipedia.org/wiki/Summation_(neurophysiology)

    Summation, which includes both spatial summation and temporal summation, is the process that determines whether or not an action potential will be generated by the combined effects of excitatory and inhibitory signals, both from multiple simultaneous inputs (spatial summation), and from repeated inputs (temporal summation).

    "In Fig. 6-1, World 1 is the world of physical objects and states. It comprises the whole cosmos of matter and energy, all of biology including human brains, and all artifacts that man has made for coding information, as for example, the paper and ink of books or the material base of works of art. World 1 is the total world of the materialists.

  4. Excitatory postsynaptic potential - Wikipedia

    en.wikipedia.org/wiki/Excitatory_postsynaptic...

    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 ...

  5. Holonomic brain theory - Wikipedia

    en.wikipedia.org/wiki/Holonomic_brain_theory

    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]

  6. Dirichlet's test - Wikipedia

    en.wikipedia.org/wiki/Dirichlet's_test

    From summation by parts, we have that = + = (+). Since the magnitudes of the partial sums B n {\displaystyle B_{n}} are bounded by some M and a n → 0 {\displaystyle a_{n}\to 0} as n → ∞ {\displaystyle n\to \infty } , the first of these terms approaches zero: | a n B n | ≤ | a n M | → 0 {\displaystyle |a_{n}B_{n}|\leq |a_{n}M|\to 0} as ...

  7. Ramanujan summation - Wikipedia

    en.wikipedia.org/wiki/Ramanujan_summation

    Ramanujan summation is a technique invented by the mathematician Srinivasa Ramanujan for assigning a value to divergent infinite series.Although the Ramanujan summation of a divergent series is not a sum in the traditional sense, it has properties that make it mathematically useful in the study of divergent infinite series, for which conventional summation is undefined.

  8. Henneman's size principle - Wikipedia

    en.wikipedia.org/wiki/Henneman's_size_principle

    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.

  9. Mehler kernel - Wikipedia

    en.wikipedia.org/wiki/Mehler_kernel

    The result of Mehler can also be linked to probability. For this, the variables should be rescaled as x → x/ √ 2, y → y/ √ 2, so as to change from the 'physicist's' Hermite polynomials H (.) (with weight function exp(− x 2)) to "probabilist's" Hermite polynomials He (.) (with weight function exp(− x 2 /2)).
