N normal phenotype
behavior/neurological
• hemizygous mutants displayed an increased startle response to several sound stimulus types including single bursts at 100db
• 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

nervous system
• 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
