Stimulus-response compatibility with body parts: a study with hands.

abstract：:In order to navigate efficiently, animals can benefit from internal representations of their moment-to-moment orientation. Head-direction (HD) cells are neurons that discharge maximally when the head of a rat is oriented in a specific ("preferred") direction in the horizontal plane, independently from position or ongo...

abstract：:Humans are known to show anticipatory adjustments in the grip force prior to a self-generated or predictable action or perturbation applied to a hand-held object. We investigated whether humans can also adjust covariation of individual finger forces (multi-finger synergies) prior to self-triggered perturbations. To ad...
