To be successful, precision manipulation of small objects requires a refined coordination of
forces excerted on the object by the tips of the fingers and thumb. The present paper deals …

During object manipulation tasks, the brain selects and implements action-phase controllers
that use sensory predictions and afferent signals to tailor motor output to the physical …

1. Single unit impulses were recorded with percutaneously inserted tungsten needle electrodes
from the median nerve in conscious human subjects. 2. A sample of 334 low threshold …

A small object was gripped between the tips of the index finger and thumb and held stationary
in space. Its weight and surface structure could be changed between consecutive lifting …

Recordings from single peripheral nerve fibres made it possible to analyse the functional
properties of tactile afferent units supplying the glabrous skin of the human hand and to assess …

We analyzed the coordination between gaze behavior, fingertip movements, and movements
of the manipulated object when subjects reached for and grasped a bar and moved it to …

While human subjects lift small objects using the precision grip between the tips of the fingers
and thumb the ratio between the grip force and the load force (ie the vertical lifting force) is …

The human hand and the brain are close partners in two important and closely interconnected
functions, ie to explore the physical world and to reshape selected segments of it …

How do we understand the actions of others? According to the direct matching hypothesis,
action understanding results from a mechanism that maps an observed action onto motor …

Most manual grips can be divided in precision and power grips on the basis of phylogenetic
and functional considerations. We used functional magnetic resonance imaging to compare …
