The Schizophrenia Research Forum web site is sponsored by the Brain and Behavior Research Foundation and was created with funding from the U.S. National Institute of Mental Health.
Animal Models

Important Notice: The Forum does not endorse any medical product or therapy. ALL medications and supplements should be taken ONLY under the supervision of a physician, due to the possibility of side-effects, drug interactions, etc.

Animal Model: Prenatal Immune Challenge: PolyI:C (Delivery Timing Varies)
Preparation Type: Developmental Preparations
DA-related behavior: No change in total distance traveled in open field but reduced center exploration; increased response to amphetamine and MK-801 (emerges after puberty; not rescued by cross-fostering)
Gating: Disrupted PPI (post-puberty; deficits not rescued by cross-fostering)
Cognitive behavior: Reduced escape latency in Morris water maze; impairment in novel object recognition memory; deficits in latent inhibition (post-puberty; deficits not rescued by cross-fostering); electrophysiology: reduced theta oscillation generated in the CA1 area of the hippocampus
Social behavior: Reduced social interaction
Molecular/morphological signature: Increased DA turnover and reduced binding to D2 receptors in striatum; reduced reelin- and parvalbumin- expressing neurons in PFC; reduced DA levels and D1 receptors in PFC; increased TH expression in striatum; reduced density of cerebellar Purkinje cells; delayed myelination of hippocampus; reduced parvalbumin-expressing neurons in the hippocampus; enlargement of lateral ventricles; impaired synaptic development of upper-layer neurons
Response to APD: Disrupted PPI was improved by clozapine and chlorpromazine; deficits in latent inhibition and novel object recognition memory were improved by clozapine but not haloperidol; deficits in Morris water maze were improve by clozapine
