The effects of practice on the functional anatomy observed in two different tasks, a verbal
and a motor task, are reviewed in this paper. In the first, people practiced a verbal production …

We argue that 4 fundamental gestalt phenomena in perception apply to the control of motor
action. First, a motor gestalt, like a perceptual gestalt, is holistic in the sense that it is …

Reaction time (RT) before a motor response has been shown to depend on the duration or
complexity of the response, indicating that responses may be programmed during RT. Some …

van Mier, H., LW Tempel, JS Perlmutter, ME Raichle, and SE Petersen. Changes in brain
activity during motor learning measured with PET: effects of hand of performance and …

Reaction time (RT) prior to speech articulation increased as a function of response
complexity. The RT findings formed 2 patterns, each of which was a different Response …

The authors investigated the online relationship between overt articulation and the central
processes of speech production. In 2 experiments manipulating the timing of Stroop …

Ampakines act as positive allosteric modulators of AMPA-type glutamate receptors and
facilitate hippocampal long-term potentiation (LTP), a mechanism associated with memory …

Abstract The Psychological Refractory Period (PRP) effect is a delay in responding that is
assumed to be caused by a bottleneck that prevents preparation of a second action until …

The balance of trained ballet dancers and non-dancer controls was mechanically perturbed
in order to evaluate the time of onset of muscle activation and the consistency of muscle …

Rationale The central cholinergic system is implicated in cognitive functioning. The
dysfunction of this system is expressed in many diseases like Alzheimer's disease, dementia …
