The hand endows us with unparalleled precision and versatility in our interactions with
objects, from mundane activities such as grasping to extraordinary ones such as virtuoso …

In this article, we challenge the usefulness of “attention” as a unitary construct and/or neural
system. We point out that the concept has too many meanings to justify a single term, and …

This article proposes that biologically plausible theories of behavior can be constructed by
following a method of “phylogenetic refinement,” whereby they are progressively elaborated …

Skilled sensorimotor interactions with the world result from a series of decision-making
processes that determine, on the basis of information extracted during the unfolding …

Neurophysiological studies of decision making have primarily focused on decisions about
information that is stable over time. However, during natural behavior, animals make …

How does the brain decide between actions? Is it through comparisons of abstract
representations of outcomes or through a competition in a sensorimotor map defining the …

Recent theoretical models suggest that deciding about actions and executing them are not
implemented by completely distinct neural mechanisms but are instead two modes of an …

The study of motor planning and learning in humans has undergone a dramatic
transformation in the 20 years since this journal's last review of this topic. The behavioral …

Neurophysiological studies of decision-making have focused primarily on elucidating the
mechanisms of classic economic decisions, for which the relevant variables are the values …

Neuroimaging studies of internally generated behaviors have shown seemingly paradoxical
results regarding the dorsolateral prefrontal cortex (DLPFC), which has been found to …
