Time Reproduction and Numerosity Interaction in the Parietal Cortex: Some Missing Links

Cognitively controlled timing and executive functions develop in parallel? A glimpse on childhood research

“…Therefore it was asserted (Lewis and Miall, 2006) that a typical automatic timing task involves continuous measurement of a series of predictable sub-second intervals defined by movements; on the other hand, a cognitively controlled timing task requires the explicit orientation of attentional sources toward the duration of stimuli lasting more than one second and characterized by some level of discontinuity (e.g., when timing is broken into discrete measurements by the presence of unpredictable irregular intervals). In reality, this distinction may be more flexible' since cognitively controlled timing tasks may also involve non-motor timing tasks of sub-second durations (e.g., time comparison tasks which require the involvement of decision-making processes—see Vicario, 2013a,b for a complete discussion on this argument) as well as supra-second motor timing tasks (e.g., the classical time reproduction).…”

Arm and Hand Movement: Current Knowledge and Future Perspective

“…In an opinion article, Moore ( 10 ) argues that nerve transfer is increasingly popular and is becoming the best treatment strategy for most brachial plexus damage as well as for patients with spinal cord injury at cervical levels. Vicario ( 11 ) provides a personal commentary on a paper from Hayashi et al ( 12 ) and, in a review article, Karl and Whishaw ( 13 ) summarize the evidence that show that reaching and grasping are from distinct neural and evolutionary origins. Irvine et al ( 14 ) contribute a methods article that assesses the reliability of the Irvine, Beatties, and Bresnahan (IBB) forelimb recovery scale.…”
