behavior/neurological

increased startle reflex ( J:101679 )

• hemizygous mutants displayed an increased startle response to several sound stimulus types including single bursts at 100db

hyperactivity ( J:101679 )

• hemizygous mutants were hyperactive, in that they displayed increased total distance traveled scores on the open field test

• hyperactivity also observed during home cage observations

increased locomotor activity ( J:101679 )

nervous system

decreased prepulse inhibition ( J:101679 )

• hemizygous mutants were significantly impaired in the Startle/PPI task, demonstrating lower prepulse inhibition scores when the prepulse was 90dB preceeding a 110dB startle stimulus
