Area of Science:

  • Neuroscience
  • Behavioral Science
  • Psychiatry

Background:

  • Isolation rearing in rodents induces neurochemical, structural, and behavioral changes relevant to schizophrenia.
  • Schizophrenia is characterized by cognitive deficits, including impaired cognitive flexibility.

Purpose of the Study:

  • To investigate the impact of isolation rearing on cognitive flexibility in rats.
  • To assess the utility of isolation rearing as a model for studying schizophrenia-like cognitive impairments.

Main Methods:

  • Cognitive flexibility was assessed using probabilistic reversal-learning tasks.
  • Behavioral pattern monitoring was used to measure unconditioned investigatory activity and locomotor habituation.
  • Sensorimotor gating was evaluated via prepulse inhibition of the startle response.

Published on: July 8, 2015

Main Results:

  • Isolation-reared rats showed deficits in cognitive flexibility, requiring more sessions to achieve criterion performance in reversal learning and slower strategy adjustment.
  • These rats exhibited reduced overall activity during the cognitive task but increased unconditioned investigatory activity and reduced habituation in a separate behavioral monitor.
  • Deficits in sensorimotor gating, indicated by decreased prepulse inhibition, were observed in isolation-reared rats.

Conclusions:

  • Isolation rearing is a valuable noninvasive model for simulating schizophrenia-like cognitive deficits, particularly in cognitive flexibility.
  • This model provides a platform for evaluating the efficacy of potential therapeutics for schizophrenia prior to clinical trials.
