behavior/neurological
hyperactivity ( J:81106 )
• animals are significantly more active than controls in an open field test, but less significantly than Nrg1 heterozygotes

nervous system
abnormal prepulse inhibition ( J:81106 )
• impairment was seen, but not as severely as in the Nrg1 heterozygous mice
• normal acoustic startle response was observed
