Abstract
Description
In the present study, the differences between addictive memory and
ordinary memory were investigated by morphine-induced and food-induced
conditioned place preference (CPP) in adolescent and adult mice. The
result showed that: 1) morphine-induced CPP could be established in
adult mice but not in adolescent mice. 2) food-induced CPP could be
established both in adolescent and adult mice. This study indicated
that between adolescent and adult mice, there was no difference in
ordinary memory, but for addictive memory, they were quite different.
Our data suggested that the development of addictive memory and
ordinary memory system in mouse brain might not be paralleled.
