Virtual reality experiments show that motorists slow down when driving in fog, but they speed up when visibility is reduced equally at all distances.

The nematode worm C. elegans consumes familiar bacterial species more rapidly than it does novel ones, and this preference for familiarity is mediated by a pair of serotonergic neurons.

The tapered, conical shape of rodent whiskers is essential for sensor mobility in constrained spaces and feature extraction from textured surfaces.

An automatic computer vision analysis approach can assist in the diagnosis of rare genetic disorders by using ordinary photographs of patients.

Neurons within rat somatosensory cortex are selective to texture and are spatially organized according to their texture preference.

Psychophysical measures of human sensitivity to visual patterns reveal that the brain preferentially processes those features of stimuli that are more variable in the natural world.

Touch information is represented with minimal noise in the somatosensory cortex during tactile exploration.

Some species of bats hunt for insects that are resting on surfaces by detecting interruptions in the echoes from that surface, suggesting that resting on rough surfaces may help insects to evade detection by echolocation.

MotionTracking is freely available software that can generate multi-scale geometrical models of mammalian tissue and perform quantitative analysis of tissue architecture.

Delivering specific patterns of electrical activity to the median nerve of the arm triggers reliable sensations of texture, suggesting that it may ultimately be possible to restore complex tactile information to users of prosthetic limbs.
