|
Animal Model:
|
Rat Antimitotic Agent – MAM or AraC
|
|
Preparation Type:
|
Developmental Preparations
|
|
DA-related behavior:
|
Enhanced response to amphetamine and MK-801 (post-puberty)
|
|
Gating:
|
Disrupted PPI (post-puberty)
|
|
Cognitive behavior:
|
Learning deficits in Morris water maze, object recognition,
and attentional set-shifting; no change in 5-choice serial
reaction time task
|
|
Social behavior:
|
Decreased social interaction (deficit present prior to puberty)
|
|
Molecular/morphological signature:
|
Reduced hippocampal volume; alterations of NMDAR protein
levels and function in the hippocampus; increased neuron
density in prefrontal cortex; enhanced NAc DA release to
amphetamine; increased firing of dopaminergic neurons;
enlarged lateral and third ventricles
|
|
Response to APD:
|
Increased response to MK-801 was attenuated by risperidone,
haloperidol, and clozapine
