Rotational eye and head movements were recorded with great precision with scleral and cranial search coils in a rotating magnetic field. Compensatory eye movements were recorded in light and darkness during active as well as passive head movements in the frequency range 0.33-1.33 Hz. From the recorded, nominal gaze movements the effective gaze was(More)
Prior work had shown that smooth eye movements depend both on the motion of the target on the retina and on the subject's expectations about future target motion (Kowler and Steinman, 1979a,b). Effects of expectation cannot be eliminated by making target motions unpredictable (Kowler and Steinman, 1981). The experiment reported here shows that effects of(More)
Accurate recordings of eye movements of children 4 and 5 years old show that their eye movements differed from those of adults. During maintained fixation, saccades were large (1 degree to 2 degrees) and smooth eye movement speeds were high (45 minutes of arc per second). Saccade latencies were highly variable during target step tracking. Smooth pursuit(More)
This paper reviews advances in our knowledge about the stability of the human being's line of sight while fixating objects stationary with respect to himself. Recent technological developments made it possible to measure gaze with a high degree of accuracy when the head was free of artificial support. Measurements made with the head free while the subject(More)
Subjects used smooth eye movements to track small-amplitude sinusoidal target motions. Target frequencies (0.05 to 5 Hz) and amplitudes (1.9 to 30 min of arc) were in the range of those found in the retinal image during fixation of a stationary target while the head is not artificially supported. Smooth pursuit was poor at high target frequencies in several(More)
We investigated whether pre-terminal axons and motor terminals retained their ability to sprout in the murine X-linked muscular dystrophy (mdx). Immunofluorescence confocal microscopy observation of nerve terminals and acetylcholine receptors in mdx muscles with crushed and non-crushed nerves showed that most of the junctions had intraterminal sprouting and(More)
Carbon based films can combine the properties of solid lubricating graphite structure and hard diamond crystal structure, i.e., high hardness, chemical inertness, high thermal conductivity and optical transparency without the crystalline structure of diamond. Issues of fundamental importance associated with nanocarbon coatings are reducing stress, improving(More)
A natural pigment (Anthocyanin extracted from Sambucus nigra L. fruit) was incorporated by dipping sputtered titanium oxide films into a pigment solution. The pigment solution has red colour and an absorption peak located in the wavelength range of 520 to 540 nm. Titanium oxide thin films were prepared by reactive DC magnetron sputtering and reactive(More)
