Summary
Brief summary
Selective attention is a cognitive skill that allows us to interpret and act in our environment. Although this skill is important, little is understoond about the neurochemical processes that are important to attention. This study will allow us to assess the importance of different brain chemicals in contributing to selective attention function.
