Seasonal effects of Selank on the behavior of hibernating animals
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
In this study of 36 arctic ground squirrels (Citellus undulatus), the authors examined seasonal effects of the peptide Selank on orientation and exploratory activity in open-field and hole-board tests. They report that Selank most notably increased behavioural activity of hibernating animals in spring and fall, had no effect on locomotor activity, and that its selective stimulation of exploratory behaviour was season-dependent, with the maximum effect under a seasonal depression-like state.
Abstract
We studied the seasonal effects of peptide preparation Selank on orientation and exploratory activity in 36 arctic ground squirrels Citellus undulatus in the open-field and hole-board tests. Selank most significantly increased behavioral activity of hibernating animals in the spring and fall. The test peptide had no effect on locomotor activity of animals. The selective stimulatory effect of Selank on exploratory behavior of hibernating animals was season-dependent. The maximum effect was observed under conditions of seasonal depression-like state.
