Memory is essential to adaptive behavior because it allows past experience to guide
choices. Emerging findings indicate that the neurotransmitter dopamine, which signals …

Progress in characterization of the nature, neural basis, and treatment of cognitive deficits in
Parkinson's disease is reviewed from the perspective of cognitive neuroscience. An initial …

The basal ganglia (BG) coordinate decision making processes by facilitating adaptive frontal
motor commands while suppressing others. In previous work, neural network simulations …

Decisions are often guided by generalizing from past experiences. Fundamental questions
remain regarding the cognitive and neural mechanisms by which generalization takes place …

The authors test a neurocomputational model of dopamine function in cognition by
administering to healthy participants low doses of D₂ agents cabergoline and haloperidol …

It has long been known that memory is not a single process. Rather, there are different kinds
of memory that are supported by distinct neural systems. This idea stemmed from early …

Parkinson's disease is characterized by the degeneration of dopaminergic pathways
projecting to the striatum. These pathways are implicated in reward prediction. In this study …

Movement variability is often considered an unwanted byproduct of a noisy nervous system.
However, variability can signal a form of implicit exploration, indicating that the nervous …

Making appropriate choices often requires the ability to learn the value of available options
from experience. Parkinson's disease is characterized by a loss of dopamine neurons in the …

In The Mind within the Brain, David Redish brings together cutting edge research in
psychology, robotics, economics, neuroscience, and the new fields of neuroeconomics and …
