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: Neonatal Ventral Hippocampal Lesion
Preparation Type: Lesion Preparations
DA-related behavior: Enhanced locomotor responses to amphetamine with post-pubertal onset; enhanced meth-amphetamine self-administration
Gating: Disrupted PPI; prolonged N40 latency
Cognitive behavior: Various impairments in learning and memory (including set-shifting and spatial working memory)
Social behavior: Impaired social behavior
Molecular/morphological signature: Reduced presynaptic protein and growth factor expression, reduced NMDA receptor expression, impaired DA receptor expression in frontal cortex; impaired maturation of PFC; brain region- and age-specific changes in GABAA receptor expression; reduced PFC spine density; enhanced sensitivity to nicotine; increased prefrontal DA output
Response to APD: Locomotor responses blocked by APD, social impairments blocked by clozapine but not haloperidol; clozapine reversed enhanced novelty-induced locomotor activity and rescued neuronal atrophy in the prefrontal cortex and nucleus accumbens
