Role of neurons of the thalamus and striopallidar complex of the human brain in ensuring the constancy of visual perception

The neuronal impulse activity during visual testing for orientation sensitivity in different head tilts was recorded in parkinsonian++ patients diagnosed and treated with long-term intracerebral electrodes implanted into different nuclei of the thalamus and striopallidar complex. It was revealed that some neuronal populations responded only to the definite orientation of the stimuli. The "preferable" orientations were not changed for the most orientation-selective neurons during left and right head positions differing by 90 degrees.     

Effects on Fertility of Rabbits After Active Immunization With Rat Testicular Cytochrome ct

ABSTRACT: A Male rabbit was immunized with rat testicular cytochrome (Cyt) c_t and mated with normal, unimmunized females. The matings resulted in abnormal pregnancies: no offspring or stillborn or undersized liveborn offspring weighing 25–30 gm each. Another unusual observation was that fur-pulling behavior, normally exhibited by pregnant female rabbits at the end of the gestational period, was absent in all of these pregnancies. Therefore, immunization of a normal rabbit with testicular cyt c_t appeared to interfere with physiological and behavioral aspects of pregnancy in normal female rabbits. The immunological basis of these findings remains to be determined.

Dermaprotecting properties of sodium succinate under conditions of impaired circulation

Sodium succinate improves the survival of a skin graft in mice, rats, and dogs normalizes histamine and serotonin concentrations in the epidermis and blood, exhibits antitoxic activity, improves microcirculation in the skin, brain, heart, kidneys, and testes without any appreciable effect on systemic arterial pressure, cardiac function, and liver blood flow in rats.
