The cutaneous contribution to adaptive precision grip.
WITNEY, ALICE (2004)Only after injury, or perhaps prolonged exposure to cold that is sufficient to numb the fingers, do we suddenly appreciate the complex neural mechanisms that underlie our effortless dexterity in manipulating objects. The ... -
The effect of externally generated loading on predictive grip force modulation.
WITNEY, ALICE (2007)A characteristic of skilled movement is the ability of the CNS to predict the consequences of motor commands. When we lift an object there is an anticipatory increase in grip force that prevents a grasped object from ... -
Enhanced motor learning following task-concurrent dual transcranial direct current stimulation.
WITNEY, ALICE (2013)OBJECTIVE: Transcranial direct current stimulation (tDCS) of the primary motor cortex (M1) has beneficial effects on motor performance and motor learning in healthy subjects and is emerging as a promising tool for motor ... -
Eye-Hand Coordination: Dextrous Object Manipulation in New Gravity
WITNEY, ALICE (ESA Publications Division, 2005) -
Internal models for bi-manual tasks
WITNEY, ALICE (2004)Co-ordinated bi-manual actions form the basis for many everyday motor skills. In this review, the internal model approach to the problem of bi-manual co-ordination is presented. Bi-manual coordinative tasks are often ... -
The kinematics of phonotactic steering in the cricket Gryllus bimaculatus
WITNEY, ALICE (2011)Female crickets, Gryllus bimaculatus, are attracted by the male calling song and approach singing males; a behaviour known as phonotaxis. Even tethered females walking on a trackball steer towards a computer-generated male ... -
Learning and decay of prediction in object manipulation.
WITNEY, ALICE (2000)Anticipating the consequences of our own actions is a fundamental component of normal sensorimotor control and is seen, for example, during the manipulation of objects. When one hand pulls on an object held in the other ... -
Predictive motor learning of temporal delays.
WITNEY, ALICE (1999)Anticipatory responses can minimize the disturbances that result from the action of one part of the body on another. Such a predictive response is evident in the anticipatory increase in grip force seen when one hand ... -
The relationship of medical, demographic and psychosocial factors to direct and indirect health utility instruments in rheumatoid arthritis.
WITNEY, ALICE (2006)Cost-effectiveness analysis (CEA) is essential for the comparison of treatments for rheumatoid arthritis (RA). CEA centres on accurate measurement of health utility (HU) preferences. Direct measures of HU in RA patients ... -
Spatial representation of predictive motor learning
WITNEY, ALICE (American Physiological Society, 2003)A key feature of skilled motor behavior is the ability of the CNS to predict the consequences of its actions. Such prediction occurs when one hand pulls on an object held in the other hand; the restraining hand generates ...
