[The interrelation between individual behavioral characteristics and the indices of brain energy metabolism in rats].
In rats with active type of behaviour in "open field" and "forced swimming" tests in response to weak stress (handling) both the rate of local blood flow (RLBF) and free oxygen tension level (pO2) in the brain are increased, and in rats with passive type of behaviour RLBF is increased, but the pO2 level is decreased. The character of pO2 level changes in the brain under stress is significantly (r = -0.74, p less than 0.001) connected with the level of depressiveness (time of passive swimming) and is nonsignificantly connected with the level of the motor activity. Indices of the active type of behaviour (the number of crossed squares, rearings, comings out to the center of the field and the time of extinction of the motor activity) positively correlate with succinate dehydrogenase (SDG) activity and negatively with NADH-dehydrogenase (NADH-DG) activity and the index of the passive type of behaviour (time of passive swimming) positively correlates with NADH-DG activity and negatively--with SDG activity.
