Mouse lines carrying:
Csktm1Sor mutation (2 available); any Csk mutation (25 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
behavior/neurological
• no increased investigation of displaced familiar objects, similar to 129P2 control but unlike C57BL/6 control
• given a chose of two novel food sources they choose a food they have already seen another mouse eat
• increased time spent exploring open arms of an elevated + maze
• increased social approach of a strange mouse as opposed to investigating an empty cage or examining a pre-exposed familiar mouse
• less time is spent re-investigating a strange mouse during second exposure to that mouse
• given a chose of two novel food sources they choose a food they have already seen another mouse eat
