Summary / Abstract
This research program seeks to describe and understand striatal dopamine (DA) signals, particularly in
the nucleus accumbens (NAc). NAc DA is a key regulator of both motivation and reward-related learning, and
drugs of abuse share the common property of enhancing NAc DA. Yet we lack a clear account of how DA
signals arise, how…
