Animal Model:	Neuregulin 1 Hypomorph (Transmembrane Domain)
Preparation Type:	Genetic Preparations
DA-related behavior:	Hyperactive in open field test
Gating:	Disrupted PPI
Cognitive behavior:	No impairment in spatial learning or working memory but diminished social recognition memory
Social behavior:	Increase in dominance related and aggressive behavior depending on environment
Molecular/morphological signature:	Reduced NMDA receptor activity; increased serotonin 2A receptors and serotonin transporters in CNS
Response to APD:	Open field behavior reversed by clozapine but not PPI
