• inhibitory postsynaptic currents (IPSCs) frequency is increased by 50% relative to in wild-type mice (J:125344)

• IPSC in response to GABA puff is increased relative to in wild-type mice (J:125344)

• IPSC strength is increased by about 50% relative to in wild-type mice (J:125344)

• spatial learning behavior in a Morris water maze is enhanced (J:125344)

• mice exhibit an increase in ability to find hidden platform in a Morris water maze and a decrease in training days (J:125344)

• after training, mice cross to the precise location of the hidden platform almost twice as often as wild-type mice (J:125344)

• response to a novel caged adult is decreased compared to in wild-type mice (J:125344)

• mice spend less time interacting with other mice compared to wild-type mice (J:125344)

• however, locomotor activity, motor coordination, exploration of novel objects, and anxiety-related behaviors are normal and mice are capable of learning social interaction behaviors following repeated exposure to the same mouse (J:125344)
