[Experimental neuroses in dogs caused by an increase in the intensity of (light) stimuli conditions].
The influence of enhanced intensity of general illumination on conditioned reactions of a different degree of complexity was studied on dogs by the classical method of secretory conditioned reflexes. In most of the dogs, increase of general illumination from 30 to 300 luxes leads to more intensive secretory conditioned and unconditioned reactions, a smaller number of errors in differentiation, and stabilization of parameters of conditioned activity, which testifies to the improved general functional state of the brain. In two animals in the same conditions of the experiment, an experimental neurosis set it, not connected with the complexity of the elaborated activity. It is assumed that the neurotizing agent was the superfluous situational (photic) stimulation which presented excessive requirements to the mechanisms regulating the general functional state of the brain.
