Examples of word excitation
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.
Here therefore the admixture of central inhibition with central excitation is a normal feature of a natural reflex.
The quantitative character of the interaction between opposed inhibition and excitation is experimentally demonstrable.
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.
