A kinematic theory of rapid human movement. Part IV: a formal mathematical proof and new insights.

A few years ago a kinematic theory was proposed to study and analyze rapid human movements. The theory relies on a model of a synergy made up of two neuromuscular systems, one agonist and the other antagonist to the movement. Representing these systems ...

Enhanced salience and emotion recognition in Autism: a PET study.

OBJECTIVE: This study examined neural activation of facial stimuli in autism when the salience of emotional cues was increased by prosodic information. METHOD: Regional cerebral blood flow (rCBF) was measured while eight high-functioning men with autism ...

Voluntary control of postural equilibrium patterns.

The ability to voluntarily transit from one whole-body movement to another is based on the multisensory integration of visual, vestibular, and somatosensory information. The role of functional sensory ranges and mechanical constraints on the ability to ...

Improvement in driving reaction time after total hip arthroplasty.

Decisions made regarding resumption of driving after total hip arthroplasty may be determined by a combination of factors including driving reaction time and when postsurgical precautions need no longer be adhered to. Ninety patients, ranging in age from ...

Retrieval orientation and the control of recollection.

Event-related potentials (ERPs) were employed to investigate whether recognition test items are processed differently according to whether they are used to probe memory for previously studied words or pictures. In each of two study-test blocks, subjects ...

Rapid reversible changes to multiple levels of the human somatosensory system following the cessation of repetitive contractions: a somatosensory evoked potential study.

OBJECTIVE: Numerous somatosensory evoked potential (SEP) studies have provided clear evidence that during repetitive voluntary movement, the transmission of somatosensory afferent information is attenuated. The objective of this work was to determine if ...

Dose-related effect of sevoflurane sedation on higher control of eye movements and decision making.

BACKGROUND: Saccadic latency may provide an objective method to assess sedative doses of anaesthetic on cortical oculomotor mechanisms and decision making. METHODS: We tested the effects of random doses of 0, 0.1, 0.2 and 0.3 MAC sevoflurane in six ...

Cognitive control mechanisms revealed by ERP and fMRI: evidence from repeated task-switching.

We investigated the extent to which a common neural mechanism is involved in task set-switching and response withholding, factors that are frequently confounded in task-switching and go/no-go paradigms. Subjects brain activity was measured using ...

Differential characteristics of the middle latency auditory evoked magnetic responses to interstimulus intervals.

OBJECTIVE: The human middle latency auditory evoked magnetic fields were recorded with different interstimulus intervals (ISI) to investigate the differential natures of P30m and the P50m, including whether the P50m source was spatially different or not ...

Intracerebral somatosensory event-related potentials: effect of response type (button pressing versus mental counting) on P3-like potentials within the human brain.

OBJECTIVE: To assess the contribution of different anatomical brain sites to the genesis of P3 phenomena with respect to button pressing versus mental counting tasks. METHODS: Eight intractable epileptic patients undergoing depth electrode recordings ...
