Appearance of Steadily
An interocular matching technique was used to investigate the variation of chromaticity and brightness following steady viewing of a chromatic test light (identical adapting and testing color). Adaptation times were of sufhcient duration to ensure stable matches. Following chromatic adaptation we found changes in hue, saturation and brightness. The spectral colors appeared desaturated. The hue ...
متن کاملJN_Spatial position information accumulates steadily over time
The acquisition of sensorimotor parameters that control goal-directed motor behaviours occurs by observing another person. During such observation, biological motion properties associated with the observed person are coded into a representation that controls motor learning. Understanding the underlying mechanisms, specifically associated with coding biological motion, has theoretical and practi...
متن کاملJet flow in steadily swimming adult squid.
Although various hydrodynamic models have been used in past analyses of squid jet propulsion, no previous investigations have definitively determined the fluid structure of the jets of steadily swimming squid. In addition, few accurate measurements of jet velocity and other jet parameters in squid have been reported. We used digital particle imaging velocimetry (DPIV) to visualize the jet flow ...
متن کاملSpatial position information accumulates steadily over time.
One of the more enduring mysteries of neuroscience is how the visual system constructs robust maps of the world that remain stable in the face of frequent eye movements. Here we show that encoding the position of objects in external space is a relatively slow process, building up over hundreds of milliseconds. We display targets to which human subjects saccade after a variable preview duration....
متن کاملExistence of Steadily Rotating Spiral Waves
In this paper, we study the existence of steadily rotating spiral waves in the kinematic theory of excitable media. The spiral wave is assumed to be a family of curves. It rotates along a circle with a constant speed such that the tip of the curve neither grows nor retracts in the tangential direction. Using an analytical approach, we are able to derive the existence and non-existence of spiral...
