I. S. Makovsky. Sound reflexes during removal of the temporal regions of the cerebral hemispheres in dogs. Thesis. St. Petersburg

The author, at the suggestion of Prof. IP Pavlova, set himself the goal of studying the properties of the so-called artificial conditioned reflexes to a break in sounds. Having prefaced a brief literary sketch of the doctrine of conditioned reflexes, the author describes the methodology for studying the mentioned reflexes in four dogs. At the same time, one dog developed a sedative conditioned reflex to a break in the sound of a chromatic pipe; two dogs developed an acidic (with hydrochloric acid) conditioned reflex to the stop of the metronome sound, and the fourth dog developed a sedative conditioned reflex to the stop of the metronome sound. A conditioned reflex to a sound break was developed in such a way that ½ minute after the sound break, which lasted 1½ minutes, the dog was given either 2.0 t. economic powder (1 tsp. meat por.+2 tsp. suharnago), if she developed a sedative reflex, or poured into her 5.0 0.25% solution of HC1, if she developed an acid reflex.
