Inhibitory Type of Nervous System in Dogs28

WithIvan P. Pavlov

An inhibitory state in the cells may be evoked either by very weak or very strong stimuli. With stimuli of medium strength the cells may remain for the longest time in a state of excitation without passing into various degrees of inhibition. During weak stimulation inhibition replaces the process of excitation slowly, during strong stimulation—rapidly. Of course, these degrees of the strength of stimuli are entirely relative, i.e., what is a strong stimulation for one nervous system is only of medium strength for another nervous system.
