Abstract
Fingers of the hand are interdependent: when a person moves one finger or produces a force with a fingertip, other fingers of the hand also move or show force production. Hence, no direct correspondence exists between the neural commands to individual fingers and finger forces. The relations among fingers are described with inter-finger connection matrices, IFM. The IFMs depend on the number of fingers involved in the task. This presentation addresses three aspects of the IFMs: (1) computation of the IFMs, (2) role of finger interdependence during manipulation of hand-held objects and (3) inter-individual differences in the IFMs.
