How dopamine drives brain activity | motor cortex, insular cortex. MIT News.
MIT biological engineers have created a specialized sensor that allows them to track dopamine in the brain using magnetic resonance imaging (MRI), as shown in the bottom row. Images in the top row show overall brain activity, as measured by functional MRI...
The MIT team found that in addition to the motor cortex, the remote brain area most affected by dopamine is the insular cortex. This region is critical for many cognitive functions related to perception of the body’s internal states, including physical and emotional states...
