Methods: Six male pilots participated in traffic pattern flight in a flight simulator. A head-mounted SIM-ETG60 eye tracking system was conducted in measuring total amount of eye movement and average of pupil diameter in five different flight phases, which contained last 10 s of cruise on the downwind leg, mid 10 s of turn and descend on the base leg, first 10 s, mid 10 s and last 10 s of final...

the summer of 1960 saw the world's first demonstration of an entirely new source of light, which on the other hand, is so concentrated and powerful that it can produce power densities billions of times as inteuse as those on the surface of sun, and, on the other hand, can be controlled so precisely that surgeons use it to perform many delicate operations on the human eye. the beam from thi...

Both the corollary discharge of the oculomotor command and eye muscle proprioception provide eye position information to the brain. Two contradictory models have been suggested about how these two sources contribute to visual localization: (1) only the efference copy is used whereas proprioception is a slow recalibrator of the forward model, and (2) both signals are used together as a weighted ...

We investigated the relationship between eye movement and simple-spike (SS) frequency of Purkinje cells in the cerebellar flocculus middle zone during the optokinetic response (OKR) in alert cats. The OKR was elicited by a sequence of a constant-speed visual pattern movement in one direction for 1 s and then in the opposite direction for 1 s. Quick-phase-free trials were selected. Sixty-six cel...

Horizontal step-ramp stimuli were used to examine gaze-, eye-, and head-movement dynamics during head-unrestrained pursuit in two rhesus monkeys. In a first series of experiments, we characterized and compared head-restrained (HR) and -unrestrained (HU) pursuit responses to unpredictable, nonperiodic, constant velocity (20-80 degrees/s) stimuli. When the head was free to move, both monkeys used...

The hardwood industry in California is not well documented and often is described as fragmented. An analysis of hardwood interests in the state reveals a wide gap between hardwood consumption and the supply of native hardwood lumber. A recent survey of individuals, companies, and agencies involved in hardwood utilization provides the data for profiling the hardwood industry. A questionnaire mai...

Introduction: Staff and patient Movement in static magnetic field MRI scanner induces current density in the human tissues, so cause biologic effects in people. The aim of this study was the Modelling of current density induced by moving individual with different velocities in static magnetic field of magnetic resonance imaging. Materials and Methods: current ...
