behavior/neurological

increased anxiety-related response ( J:242006 )

• in the novelty-induced hypophagia test, adult males show a significantly longer latency to drink milk in a novel, brightly lit cage as well as reduced milk consumption relative to controls, indicating increased anxiety

• however, no significant differences are noted in the light/dark transition or marble-burying tests

nervous system

decreased CNS synapse formation ( J:242006 )

• at P21, Stat1 expression in the cortex is significantly higher than in controls
