The ubiquitous presence of plastic debris in the ocean is widely recognized by the public, scientific communities, and government agencies. However, only recently have microplastics in freshwater systems, such as rivers and lakes, been quantified.

DA release in the nucleus accumbens is reduced in rats treated chronically with the mood stabiliser lithium, and this effect is maintained for 3 days after withdrawal from the lithium treatment. We tested whether this decrease in DA release is due to an increase in D(2/3) autoreceptor sensitivity.
