Bio‐Inspired Artificial Ionic Mechanoreceptor
Advanced Functional Materials, EarlyView.A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

Disinhibition in the Human Visual System*
Journal of the Optical Society of America, 1962By the method of binocular photometry, the present experiment has demonstrated that it is possible to reduce the magnitude of simultaneous brightness contrast through an increase in the number of inducing targets presented to an observer. This demonstration is thought to be important for two reasons: (1) it is a perceptual analog of the indirect ...

Electrophysiology of the human visual system
Ophthalmic and Physiological Optics, 1983Abstract Progress during the last 60 years has revealed numerous electrical signals arising from many parts of the visual system. These now play an essential part in the detection of many pathological conditions.

Task dependency of visual processing in the human visual system
Behavioural Brain Research, 1996In this review we contrast passive, attribute driven processing in the visual system with an active, task-dependent view and summarize the evidence from our Positron Emission Tomography (PET) work supporting the task-dependent view. The PET studies involved comparison of regional Cerebral Blood Flow (rCBF) in closely related detection and ...

Stimulus specificity in the human visual system
Vision Research, 1973Abstract During adaptation to a high contrast grating it gradually seems to fade. A lower-contrast test grating appearing directly after the adapting pattern appears reduced in apparent contrast. The orientation specificity and spatial frequency specificity of thisapparent contrast reduction have been determined by adapting to gratings of various ...

Speed of processing in the human visual system
American Journal of Ophthalmology, 1996How long does it take for the human visual system to process a complex natural image? Subjectively, recognition of familiar objects and scenes appears to be virtually instantaneous, but measuring this processing time experimentally has proved difficult.

Sex differences in the human visual system
Journal of Neuroscience Research, 2016This Mini‐Review summarizes a wide range of sex differences in the human visual system, with a primary focus on sex differences in visual perception and its neural basis. We highlight sex differences in both basic and high‐level visual processing, with evidence from behavioral, neurophysiological, and neuroimaging studies. We argue that sex differences

Temporal beats in the human visual system
Vision Research, 1994The human visual system is generally assumed to comprise multiple independent channels tuned to limited ranges of spatial and temporal frequency. However, it is known that spatial beats effectively mask a sinusoidal grating whose spatial frequency coincides with the beat frequency of the mask, even though no Fourier energy exists in the mask at that ...
