behavior/neurological
• in a discrete T-maze paradigm with a 5-second delay, mice show reduced alternation indicating impaired spatial working memory
• about 25% of mice develop skin lesions caused by self-injurious, over-grooming behavior
• mice exhibit enhanced startle amplitudes, indicative of increased sensory-motor reactivity
• mice exhibit forepaw clasping/wringling behavior during tail suspension at a greater rate than controls
• activity patterns across the light-dark cycle indicate increased locomotor activity, which is more apparent during the light cycle
• in a mating paradigm, males initiate less social contact with an unfamiliar wild-type female than control males
• in a same-sex 3 chambered social approach/avoidance paradigm, males show reduced sociability compared to controls
• males emit fewer vocalizations during female social interaction than control males and the peak frequency of calls emitted is lower than in controls

hearing/vestibular/ear
• the phase-locked early auditory gamma-band response is reduced indicating deficits in neural synchrony
• mice show a 10-15% delay in the latency of the N1 component of the auditory-evoked response, however the amplitudes of P1 and N1 peaks are not different
