We measured saccadic eye movements in 168 normal human subjects, ranging in age from 5 to 79 years, to determine age-related changes in saccadic task performance. Subjects were instructed to look either toward (pro-saccade task) or away from (anti-saccade task) an eccentric target under different conditions of fixation. We quantified the percentage of(More)
Horizontal saccadic reaction times (SRTs) have been extensively studied over the past 3 decades, concentrating on such topics as the gap effect, express saccades, training effects, and the role of fixation and attention. This study investigates some of these topics with regard to vertical saccades. The reaction times of vertical saccades of 13 subjects were(More)
We studied the characteristics of combined eye-head gaze shifts in human subjects to determine whether they used similar strategies when looking at visual (V), auditory (A), and combined (V + A) targets located at several target eccentricities along the horizontal meridian. Subjects displayed considerable variability in the combinations of eye and head(More)
To examine the natural history and pathogenesis of parkinsonism in Alzheimer's disease, 44 subjects with clearly established senile dementia of the Alzheimer type were studied during a 66-month period. Sixteen subjects (36%) developed idiopathic parkinsonism, and 12 subjects (27%) developed drug-induced parkinsonism; the chief clinical features of both(More)
The perception of speech of 167 children implanted with a CLARION Multi-Strategy Cochlear Implant (1.2 device) was evaluated preimplantation and at 3, 6, 12, 18, and 24 months postimplantation. The children were between 15 months and 15 years of age. The test materials consisted of 8 tests involving syllable structure, single- and 2-syllable words,(More)
A controlled trial has been carried out in 50 patients undergoing elective colonic surgery to assess the efficacy of prophylactic oral metronidazole specifically directed against anaerobic colonic microflora in combination with kanamycin to reduce the aerobic flora. A control group received dietary and mechanical preparation alone. A significant reduction(More)
A new straight thin electrode array (universal electrode) was designed to be used together with a positioner, which will place the electrode array at the medial wall (modiolus) of the cochlea. The study objectives were to demonstrate safety and ease of insertion, tissue trauma, electrode position, and depth for universal and standard electrodes in human(More)
—Aspect-Oriented Programming (AOP) has remained a controversial idea, for over decade. Its main objective is to improve the software development process and separate concerns using aspects. In this paper, AOP is compared to OOP. Both methodologies have their relative strengths and weaknesses that may influence the function of certain systems, in different(More)
