Auditory fear conditioning modulates prepulse inhibition in socially reared rats and isolation-reared rats.
Prepulse inhibition (PPI) is the reduction of the startle reflex when the startling stimulus is shortly preceded by a non-startling stimulus. Previous studies have shown that PPI in rats can be enhanced by auditory fear conditioning (AFC) but weakened by isolation rearing. This study investigated whether isolation rearing affects the effect of AFC on PPI. The results show that PPI was lower in ...
متن کاملEffect of Intracerebroventricular Morphine Withdrawal on the Anxiety Behavior in Male Rats Reared in Social Isolation
Aims: Prescription of narcotics has controversial effects on the occurrence of anxiety processes. On the other hand, the social isolation has been caused due to the drug consumption, but its acute and chronic effects on behavioral differences are not obvious in the process of dependency and withdrawal. The present study aimed to investigate effects of acute and chronic intracerebroventricular M...
متن کاملChronic administration of clozapine alleviates reversal-learning impairment in isolation-reared rats.
Isolation rearing has been used for inducing schizophrenia-like symptoms in rats. Human schizophrenics have deficits in prefrontal-dysfunction-related cognitive/behavioral flexibility. Rats with lesions of the medial prefrontal cortex perform poorly in reversal learning. It is uncertain whether isolation rearing, however, causes reversal-learning impairment in adult rats. Using the rotating T m...

The effects of subchronic social and isolation stresses on learning and memory trend in male rats
Introduction: Psychological stresses influence brain functions such as learning and memory. Environmental factors like types and durations of stress affect brain responsiveness. This study investigated the effects of two subchronic social and isolation stresses on learning, memory, adrenal glands weight and corticosterone levels in the hippocampus and frontal cortex. Methods: Eighteen male ...
