Many studies have implicated the basal ganglia in the suppression of action impulses
('stop**'). Here, we discuss recent neurophysiological evidence that distinct hypothesized …

Although there is no clear concept of volition or the will, we do have intuitive ideas that
characterize the will, agency, and voluntary behavior. Here I review results from a number of …

Salient cues can prompt the rapid interruption of planned actions. It has been proposed that
fast, reactive behavioral inhibition involves specific basal ganglia pathways, and we tested …

For nearly 50 years, the dominant account of decision-making holds that noisy information is
accumulated until a fixed threshold is crossed. This account has been tested extensively …

Abstract [Correction Notice: An erratum for this article was reported in Vol 118 (1) of
Psychological Review (see record 2011-00732-008). The presentation of the colors in …

Perceptual decision making requires a complex set of computations to implement, evaluate,
and adjust the conversion of sensory input into a categorical judgment. Little is known about …

We describe a stochastic accumulator model demonstrating that visual search performance
can be understood as a gated feedforward cascade from a salience map to multiple …

Humans are metacognitive: they monitor and control their cognition. Our hypothesis was that
neuronal correlates of metacognition reside in the same brain areas responsible for …

Locomotion engages widely distributed networks of neurons. However, our understanding of
the spatial architecture and temporal dynamics of the networks that underpin walking …

The cerebral cortex generates flexible behavior by learning. Reinforcement learning is
thought to be driven by error signals in midbrain dopamine neurons. However, they project …
