The field potential and temperature of the cerebral cortex were studied in
right-handed, left-handed, and ambidextrous rats. Temperature asymmetry of
the cerebral hemispheres was revealed, which proved to differ in rats with
different types of interhemispheric asymmetry: the interhemispheric tempera
ture gradient was maximal in left-handed rats, minimal in right-handed rats
, and intermediate in ambidextrous rats. Both parameters of energy metaboli
sm (field potential and temperature of the cerebral cortex) correlated with
one another, and the structure of these statistically significant correlat
ions was different in right-handed, left-handed, and ambidextrous rats. It
is suggested that the previously known types of interhemispheric asymmetry-
biochemical, neurophysiological, and organoelement-are based on differences
in the intensity of energy-consuming processes in the cerebral hemispheres
.
