Table 1.

The behavioral phenotypes that were assessed from the MCSF maze (first column). Each phenotype analysis included specific behavioral measures obtained from the scoring with Observer XT and analyzed as described in the text.

Exploratory Behavior	Duration of hurdle visits	Hurdle duration per visit	Number of photocell counts	Latency to initial slope visit	Latency to initial hurdle visit	Center Duration per visit
Risk Assessment	Latency to leave center arena	Slope duration per visit	(Latency to initial bridge visit)- (Latency to initial slope visit)
Risk-taking havior Be	Duration of bridge visits	Bridge duration per visit	Duration of center circle visits	Center circle duration per visit
Shelter Seeking	Frequency of dark corner room	Duration of dark corner room	Duration per visit of dark corner room	Latency to initial DCR visit
