Examples

  • The musical notes of the string are called excitation modes compared to the string at rest.

  • They react only weakly to chemical reagents which produce strong dilation in the tongue, and while very slight mechanical irritation can cause some dilation, as a rule they contract when the excitation is stronger.

    August Krogh - Nobel Lecture

  • Here therefore the admixture of central inhibition with central excitation is a normal feature of a natural reflex.

    Sir Charles Sherrington - Nobel Lecture

  • The quantitative character of the interaction between opposed inhibition and excitation is experimentally demonstrable.

    Sir Charles Sherrington - Nobel Lecture

  • The standard excitation is found to be then diminished (as shown by the twitch-contraction which it evokes) more than it is if subjected to either one inhibitory volley only.

    Sir Charles Sherrington - Nobel Lecture

  • Here the initial reflex excitation is closely followed by an ensuing reflex inhibition commingled with and partially counter-acting the concurrent excitation.

    Sir Charles Sherrington - Nobel Lecture

  • Since reciprocal innervation has been observed to obtain between these muscles, the phase of lapse of excitation is probably one of filer active inhibition.

    Sir Charles Sherrington - Nobel Lecture

  • "for their discoveries concerning the ionic mechanisms involved in excitation and inhibition in the peripheral and central portions of the nerve cell membrane"

    Medicine 1963

  • An extremely feeble stimulus is below the limit of perception, a moderate stimulus transmits excitation, which is perceived as sensation of not an unpleasant character, but the tone of sensation becomes painful when the excitation is very intense.
