Asmann, S. (2006). A Behavioral Investigation of an Isolation-Rearing Model of Schizophrenia in Rats.
Mentor: Dr. Anne Marie Brady
Isolation-rearing of rats leads to behavioral and neurochemical changes including deficits in pre-pulse inhibition, locomotor hyperactivity, and impairments in spatial learning. These behaviors are analogous to vulnerability to stress and cognitive deficits in human schizophrenia. This experiment addresses the relationships between these three behaviors through the use of acoustic startle, locomotor assessment in an activity chamber and a radial arm maze task. The hypothesis was that animals raised in isolation would have greater PPI deficits, increased locomotor hyperactivity, and more difficulty completing a radial arm maze task. These behaviors were hypothesized to be positively correlated with one another. The research showed a significant increase in PPI deficit and difficulty in a radial arm maze task, but did not support the locomotor activity hypothesis or correlational hypothesis.
