Researchers performed studies on rats with cocaine to study relapse and that “addiction is a maladaptive form of memory and learning” (Discover‚ 2015‚ para 42)‚ which further explains drug relapse and possibly leads to being able to prevent relapse.

The motivation to quit a drug substance is managed in the primitive areas of the brain‚ amygdala and hippocampus

Aim: To test the role of the environment factors on brain plasticity in rats Procedure: The rats were placed in separate groups. One group had an enriched environment with a lot of food and toys. The other group had a deprived environment. The rats stayed in their groups for about 30 to 60 days Findings: The rats in the group that had the enriched environment had a thicker level of neurons compared to the deprived group of rats Critique: Hard to generalize with humans‚ small sample size Paragraph
