  • aLeft columns show EPM performance. Nse-RCAN1Tg1a mice show reduced open-arm time relative to controls while other manipulations of RCAN1 overexpression did not affect open-arm time. Right columns show normal PPI of the acoustic startle response in RCAN1-overexpressing transgenic lines tested. See Materials and Methods for detailed genotype description. Dist, Distance traveled; Vel, ambulatory velocity. PPI percentage inhibition based on inhibition compared to the startle response to intertrial pulses.
