Asymmetry of blinking.
PURPOSE Too investigate asymmetry in eyelid movements with blinking, the stability of the asymmetry, and its modifiability in normal humans. METHODS Differences in the start time and amplitude between the two eyelids were assessed for voluntary blinks and reflex blinks evoked by supraorbital trigeminal nerve stimulation. These variables were also measured before and up to 18 months after 2 ho...
متن کاملDynamics of blinking vortices.
We investigate the dynamics of N moving point vortices, whose vorticity changes periodically between a finite value and zero. The dynamics of such blinking vortices is chaotic, but the degree of chaoticity, expressed in terms of finite size Lyapunov exponents, decreases monotonically with time. In contrast to traditional point vortices, the average diameter of the blinking vortex system increas...
متن کاملDynamics of Stochastically Blinking
We study stochastically blinking dynamical systems as in the companion paper (Part I). We analyze the asymptotic properties of the blinking system as time goes to infinity. The trajectories of the averaged and blinking system cannot stick together forever but the trajectories of the blinking system may converge to an attractor of the averaged system. There are four distinct classes of blinking ...
متن کاملThe blinking spotlight of attention.
Increasing evidence suggests that attention can concurrently select multiple locations; yet it is not clear whether this ability relies on continuous allocation of attention to the different targets (a "parallel" strategy) or whether attention switches rapidly between the targets (a periodic "sampling" strategy). Here, we propose a method to distinguish between these two alternatives. The human...
متن کاملLuminescent blinking of gold nanoparticles
Spin-coated gold colloids showed a time-dependent increase in emission upon illumination at 532 nm. The emission originated from point-like locations and displayed blinking. The emission spectra of the individual spots and their spatial location remained constant, which is distinct from recent reports on silver nanoparticles. These results suggest the use of emission from gold clusters in nanop...
