The relationship between the proteolytic activity in the basal nuclei and locomotion in the open-field test under the conditions of an altered photoperiod

Abstract

The effect of an altered photoperiod on the proteolytic activity in the basal nuclei, including the caudate nucleus, globus pallidus, nucleus accumbens, and amygdala complex, and rat behavior in the openfield test was studied. The altered photoperiod modulated the functional state of the basal nuclei, which was reflected in the locomotor activity of the animals.
