The ability to change initial decisions in the face of new or potentially conflicting information
is fundamental to adaptive behavior. From perceptual tasks to multiple-choice tests …

Humans spend a lifetime learning, storing and refining a repertoire of motor memories. For
example, through experience, we become proficient at manipulating a large range of objects …

A decision is a commitment to a proposition or plan of action based on evidence and the
expected costs and benefits associated with the outcome. Progress in a variety of fields has …

Decisions are accompanied by a degree of confidence that a selected option is correct. A
sequential sampling framework explains the speed and accuracy of decisions and extends …

Motor and sensory loss or dysfunction affects the quality of life for thousands of individuals
daily. The upper limb, and especially the hand, are important for a person's ability to …

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique
that alters cortical excitability in a polarity specific manner and has been shown to influence …

Recent theories of limb control emphasize motor cortex as a dynamical system, with
planning setting the initial neural state, and execution arising from the self-limiting evolution …

Both decision making and sensorimotor control require real-time processing of noisy
information streams. Historically these processes were thought to operate sequentially …

Humans have been shown to combine noisy sensory information with previous experience
(priors), in qualitative and sometimes quantitative agreement with the statistically-optimal …

Recent theory proposes that the brain, when confronted with several action possibilities,
prepares multiple competing movements before deciding among them. Psychophysical …
