Animal Model:
|
Rat Placental Insufficiency/Birth Insults
|
|
Preparation Type:
|
Developmental Preparations
|
|
DA-related behavior:
|
Enhanced amphetamine-induced locomotion and accumbal
dopamine release
|
|
Gating:
|
Disrupted PPI (post-pubertal onset)
|
|
Cognitive behavior:
|
Performance on Morris water maze and T-maze appears normal
|
|
Molecular/morphological signature:
|
Reduced DA release in PFC, increased DAT in NAc (basal),
decreased DA receptor expression; reduced dentate granule
cells; region- and age-specific alterations in dendritic
spine development; altered expression of presynaptic genes;
decreased caudate-putamen volume
|
|
Response to APD:
|
PPI deficits reversed by clozapine
|
