♀	phenotype observed in females
♂	phenotype observed in males
N	normal phenotype

behavior/neurological

increased exploration in new environment ( J:220448 )

• open field exploratory behavior is greater than controls at day 1

• although exploratory behavior declines by day 2, it remains greater than in controls

decreased anxiety-related response ( J:220448 )

• stayed significantly longer in the open arms of an elevated maze than do controls

abnormal locomotor activation ( J:220448 )

• significantly greater locomotor activity than controls or heterozygotes when housed alone for three days

increased locomotor activity ( J:220448 )

• greater hyperlocomotion in the active phase of the circadian cycle than seen in other genotypes

• transient hyperlocomotion induced by methylphenidate (MPH)
