Goby fins have fingertip sensitivity

Spectral sensitivity of the two-spotted goby Gobiusculus flavescens (Fabricius): a physiological and behavioural study.

Microspectrophotometry of Gobiusculus flavescens photoreceptors revealed a single rod visual pigment (lambdamaxat 508 nm) and the three cone pigments (lambdamax 456, 531 and 553 nm). The cone population was dominated by identical double cones containing the middle-wave-sensitive (MWS) pigment, but with a small number of non-identical MWS/LWS (long-wave-sensitive) and identical LWS double cones....

Hierarchical Fingertip Space for Synthesizing Adaptable Fingertip Grasps

The ability to synthesize and execute fingertip grasps are bases for dexterous in-hand manipulation. Reliable fingertip grasping is difficult to achieve due to noise and uncertainties in object and hand model, as well as hand control etc. Moreover, in many cases it is desirable to employ an adaptive approach that can deal with changed external forces. In this paper, we propose an approach to jo...

Mice lacking NKCC1 have normal olfactory sensitivity.

When olfactory receptor neurons respond to odors, a depolarizing Cl(-) efflux is a substantial part of the response. This requires that the resting neuron accumulate Cl(-) against an electrochemical gradient. In isolated olfactory receptor neurons, the Na(+)+K(+)+2Cl(-) cotransporter NKCC1 is essential for Cl(-) accumulation. However, in intact epithelium, a robust electrical olfactory response...

[Fingertip injuries in children].

Traumatisms of distal extremities are frequent in children. They can associate fingertip skin, bone and nail complex injuries. Their severity level is very variable, from simple subungual bruise to distal amputation. Initial care needs careful repair of injured structures. Secondary treatment of sequelae is much more difficult.

SA-I mechanoreceptor position in fingertip skin may impact sensitivity to edge stimuli
