Some Behavioral Differences in Mice Genetically Selected for High and Low Brain Weight

摘要: Learning ability, exploratory behavior, and emotionality were measured in mice genetically selected for high low total brain weight. The selection lines scored significantly higher than the locomotor activity open field discrimination learning performance a water maze, these findings supported by correlations between weight behavioral scores within unselected control lines. There is some evidence that differences are associated with general changes size produced genetic selection.
