Limbic Structures and Behavior: Endocrine Correlates.

摘要

This paper concludes that, in rats with limbic lesions, the corticosterone levels change in accordance with changes in motivation, reinforcement effect, or problem-solving ability. Without measuring a reliable indicator of the internal state of the rat, it is difficult to decide which psychological mechanisms are involved. For all the groups studied, the corticosterone response does not depend in any simple 'physical' way on the external situation such as shock levels. A very importance factor is how the rat behaves, or, more accurately, how the rat perceives and solves the problem.
