Local adaptation in stabilized vision.
The increment threshold for a small stimulus superimposed upon adapting spots ofvarious diameters was measured under scotopic conditions in the peripheral retina. Confirminy~‘ESTHEIMER (lY65), it was found that adapting spots of about 1’ diameter raise rhe thresholdmore than either larger or smaller spots. This experiment v,as repeated using a stabilized-imagetechnique to avoid ...
متن کاملVisuomotor adaptation without vision ?
an aftereffect following treadmill running was described, in which people would inadvertently advance when attempting to run in place on solid ground with their eyes closed. Although originally induced from treadmill running, the running-in-place after-effect is argued here to result from the absence of sensory information specifying advancement during running. In a series of experiments in whi...
متن کاملRapid Adaptation of Night Vision
Apart from the well-known loss of color vision and of foveal acuity that characterizes human rod-mediated vision, it has also been thought that night vision is very slow (taking up to 40 min) to adapt to changes in light levels. Even cone-mediated, daylight, vision has been thought to take 2 min to recover from light adaptation. Here, we show that most, though not all adaptation is rapid, takin...
متن کاملDynamic Adaptation in Fly Motion Vision
Sensory neurons process and convey information about our surroundings, providing the physiological basis for how we interact with the external world. In order to understand neuronal responses we must identify the rules governing how sensory information is encoded. It was proposed more than fifty years ago that neural codes constitute efficient representations of the natural world (Attneave, 195...
متن کاملAdaptation and perceptual norms in color vision.
Many perceptual dimensions are thought to be represented relative to an average value or norm. Models of norm-based coding assume that the norm appears psychologically neutral because it reflects a neutral response in the underlying neural code. We tested this assumption in human color vision by asking how judgments of "white" are affected as neural responses are altered by adaptation. The adap...
