25. Analise dos fenomenos sonoros articulares do joelho atraves de processamento digital / Analysis of the knees articular sonorous phenomena using digital processes
The purpose of this study is to investigate the knees articular sonorous phenomena, through arthrosonography, using digital processes. Two hundred and fifteen (215) volunteers, of both sexes, with ages varying between 10 and 75, participated in this study. From this total, 145 volunteers didn t have a historic of articular diseases and 70 had rheumatic disea

27. The value of measuring saccadic eye movement in the investigation of non-compressive myelopathy.
Saccadic eye movement recording was performed in 53 patients with non-compressive myelopathy. Twenty one patients (40%) had subclinical abnormalities of saccadic movement, supporting a diagnosis of probable multiple sclerosis. When used in addition to the measurement of visual evoked potentials and brainstem auditory evoked responses, the detection of subcli

28. Motility Tracks: Technique for Quantitative Study of Bacterial Movement
A method for recording movements of bacteria in time and space on a single photograph is described. Quantitative information on the behavior of various motile organisms may easily be obtained for comparative studies. The method possesses certain advantages over cinematography, and illustrations of applications of the technique are presented.

29. The photomyoclonic reflex: an artefact in the clinical electroretinogram.
An artefact may appear in the clinical electroretinogram (ERG) that can interfere with the recording and interpretation of the ERG b wave. This artefact, the photomyoclonic reflex (PMR), was studied by covering the eye containing the recording electrode and stimulating the fellow eye. Records obtained by this technique before and after administration of a mo

30. Mechanisms of pain relief by vibration and movement.
Mechanisms of pain relief induced by vibration and movement were investigated. A CO2 laser beam, which is useful for pure nociceptive stimulation, was used for recording pain-related somatosensory evoked potentials (pain SEPs) and for measuring pain threshold and reaction time (RT). Concurrently applied vibratory stimuli to and active movements of the finger

31. Continuous attraction toward phonological competitors
Certain models of spoken-language processing, like those for many other perceptual and cognitive processes, posit continuous uptake of sensory input and dynamic competition between simultaneously active representations. Here, we provide compelling evidence for this continuity assumption by using a continuous response, hand movements, to track the temporal dy

32. Oscillations in local field potentials of the primate motor cortex during voluntary movement.
We investigated the occurrence and distribution of oscillatory activity in local field potentials (LFPs) recorded from the frontal motor cortex of behaving monkeys performing skilled voluntary movements. LFPs were recorded simultaneously from up to 12 sites distributed throughout motor cortex while monkeys performed a visually guided, instructed delay task u

33. Dynamic electron microscopy of ATP-induced myosin head movement in living muscle thick filaments
Although muscle contraction is known to result from movement of the myosin heads on the thick filaments while attached to the thin filaments, the myosin head movement coupled with ATP hydrolysis still remains to be investigated. Using a gas environmental (hydration) chamber, in which biological specimens can be kept in wet state, we succeeded in recording im

34. Levodopa induced ON-OFF motor fluctuations in Parkinson's disease related to rhythmical masticatory jaw movements.
The motor disturbance in Parkinson's disease affects all voluntary movement, including innate rhythmical processes such as gait, breathing, and chewing. While there are good descriptions and pathophysiological hypotheses of the changes in gait less is known about the way masticatory movements are affected. By means of a three-dimensional optoelectronic recor

35. Control of a two-dimensional movement signal by a noninvasive brain-computer interface in humans
Brain-computer interfaces (BCIs) can provide communication and control to people who are totally paralyzed. BCIs can use noninvasive or invasive methods for recording the brain signals that convey the user's commands. Whereas noninvasive BCIs are already in use for simple applications, it has been widely assumed that only invasive BCIs, which use electrodes

36. Posturo-kinetic organisation during the early phase of voluntary upper limb movement. 1. Normal subjects.
The nature and organisation of anticipatory postural adjustments (APA) associated with the early phase of a voluntary upper limb movement were studied. Upper limb elevations, performed at maximal velocity, were studied according to three conditions: bilateral flexions (BF) and unilateral flexions without and with an additional inertia (respectively OUF and I
