1. Subjects sat with their right hands in a mould which was attached to the shaft of a servo-controlled motor. 2. There were two different tasks. In one, the subject attempted to maintain a constant wrist flexing force, while the motor imposed flexion-extension movements. In the other, the subject attempted to maintain a constant wrist position while the(More)
1. Subjects flexed the interphalangeal joint of the index finger against a lever which was mounted on the shaft of a torque motor. 2. There were two different tasks. In one, the subject attempted to maintain a constant finger position in the face of changing forces, whereas in the other the subject attempted to maintain a constant force while the motor(More)
A fast route for transmission of deep and cutaneous afferent information to the frontal cortex is well established in non-human primates. Whether the incoming cortical information gives rise to early frontal somatosensory evoked potentials (SEPs) in humans is still a matter of contention. We attempted to solve this question by investigating the topography(More)
Disturbed motor control of the fingers, as revealed by the response to unexpected loading of an object held in a precision grip, or to finger perturbation during isometric holding, has been studied in patients with Huntington's disease (HD) and in normal subjects. In normal subjects unexpected loading elicited a reflex response (mean latency 73 ms) in the(More)
1. In order to establish the afferent source responsible for the M1 and M2 stretch reflex components of the voluntarily activated human triceps surae muscle, mechanical reflex testing was applied before and during ischaemic blockade of the lower limb. This procedure is known to affect large, fast conducting afferent fibres earliest, specifically Ia(More)
This paper presents a corpus-based method for automatic evaluation of geometric constraints on projective prepositions. The method is used to find an appropriate model of geometric constraints for a twodimensional domain. Two simple models are evaluated against the uses of projective prepositions in a corpus of natural language dialogues to find the best(More)
