Animal Model: Brattleboro (Vasopressin-Deficient) Rat
Preparation Type: Genetic Preparations
DA-related behavior: Hyperactive in novel setting
Gating: Increased acoustic startle and decreased PPI
Social behavior: Impaired social discrimination
Molecular/morphological signature: Point mutation in gene for vasopressin; decreased dopamine concentration in frontal cortex
Response to APD: PPI deficit reversed by acute clozapine and risperidone; chronic but not acute haloperidol reverses deficit
