    Abstract:
    Neurotransmitter reactions--concentration of acetylcholine, adrenaline and noradrenaline in blood after an open field test were compared with characteristics of motor activity in it observed in three groups of rats with different behavioural manifestations. It was noted that these characteristics may reflect relatively independent manifestations of activity: the rats of two most different behavioural groups (elaborating and not elaborating the avoidance of a closed space at the cries of a partner), with unequal speed of alimentary reflex elaboration, differed significantly by their behaviour in the open field, but comparatively little by their neurotransmitter reactions. Only 25% of the first group rats had an increased content of noradrenaline, while in the group which occupied an intermediate position by the majority of behavioural characteristics, the activity of the neurotransmitter was the greatest. After the procedure of elaboration of alimentary reflexes a distinct decrease of this activity in all groups took place.
