Animal Model:
|
Rat Prenatal Variable Stress
|
|
Preparation Type:
|
Developmental Preparations
|
|
DA-related behavior:
|
Increased response to amphetamine and PCP with post-pubertal
onset
|
|
Gating:
|
Disrupted PPI and N40
|
|
Cognitive behavior:
|
Impaired object and social recognition; deficits in Morris
water maze; impaired cued and contextual fear conditioning;
impairment in sustained attention and inhibitory response
control
|
|
Social behavior:
|
Impaired social interaction present in adolescent and adult
rats; reversal by oxytocin; no effect of cross-fostering
|
|
Molecular/morphological signature:
|
NMDA, GABAergic and presynaptic protein dysregulation;
reduced hippocampal neurogenesis and hippocampal volume;
decreased BDNF protein expression in the hippocampus (strain
dependent); altered pattern of apical dendritic maturation
of pyramidal neurons (males only)
|
|
Response to APD:
|
Social interaction deficit not improved by haloperidol
|
