Data suggesting that different brain circuits may underlie different forms of learning and memory are reviewed. Several current theories of learning and memory with respect to hippocampal and other brain circuit involvement are considered. (PCB)

A general learning impairment model and a reasoning insight model, both in rats, were reviewed for parallels to theories of human cognitive deficiency, leading to the conclusion that animal models of the cognitive deficiency states of mental retardation are underutilized and that human mental retardation researchers would benefit from greater…

This article outlines a strategy for studying early social relationships in relatively simple animal model systems. It describes some of the differences in approach between neuroscientists and human developmentalists in dealing with the same research problems. (BN)
