title: [The comparison of levels of anxiety and stress response in mice selected for low and high brain weight].
abstract: Emotionality, anxiety and stress reactivity were studied in mice selected for large (LW) and small (SW) brain weight. The open-field test, startle reaction, cross-maze, tail suspension and slippery funnel tests were used. It was shown that the SW mice are more active in the open field, more anxious and predisposed to the stereotyped behavior and passive reactions in stress situations. The relationship between the studied traits and brain weight and their influence on cognitive behavior are discussed.
