Chemical investigations--early concept brain research

Dopamine is a special chemical, neurologically speaking. The neurotransmitter is crucial for decision-making, learning, movement and more. Scientists know that varying dopamine levels affect neurons, but don't yet have a method to measure exactly how. Michael Heien and Stephen Cowen from the University of Arizona are developing a tool that will simultaneously measure dopamine release and the activity of groups of neurons. The technology will help provide a real-time picture of how dopamine affects abilities such as motor control and learning.
