[The respiration and oxidative phosphorylation of the brain mitochondria in rats with different types of behavior].
Respiration and oxidative phosphorylation of brain mitochondria were studied in outbred rats with different types of behaviour in open-field test and in forced swimming test. It was found that in rats with "active" type of behaviour (with high locomotor activity and low level of depressiveness) the brain mitochondria have at succinate oxidation a higher rate of respiration in active metabolic state and in presence of uncoupler 2,4-DNP, and a higher rate of ADP phosphorylation than in rats with "passive" type of behaviour (with low locomotor activity and high and moderate levels of depressiveness). Thus rats with active type of behaviour have a higher succinate oxidase activity than rats with passive type of behaviour. It is supposed that revealed differences in brain energy metabolism may affect the dominance of certain type of behaviour.
