["Protective" role of anterior sections of the brain in relation to pathological heart reflexes].
A study was made of the character of hypothalamic modulating influences in frogs on the adaptive cardiocardiac reflexes and the pathological patterns of the viscerocardiac reflexes. The number of the facilitating effects on the viscerocardiac reflexes was discovered to be less as compared to that of the effects on the cardiocardiac reflexes. This was particularly manifest in the after-action. The cases of the reversal response were recorded: transformation of appreciable bradycardia to tachycardia. The pathological forms of the cardiocardiac reflexes in cats that are manifested in appreciable bradycardia experience, in all the cases, only the inhibitory effect on the part of the large hemispheres, thus suggesting a physiologically advisable control of the higher "centres" over lower ones.
