Abstract

The backward masking effects of the offset of a pattern stimulus on the apparent contrast of a target stimulus were determined to be a function of target onset-mask offset asynchrony. With spatially overlapping stimuli and binocular viewing, a monotonic function similar to that characterizing early dark adaptation was obtained; with a dichoptically presented disk onset as target and a surrounding ring offset as mask, a typical U-shaped metacontrast effect as a function of target onset-mask offset asynchrony was obtained. These mask-offset effects are related to the possible roles of (a) peripheral "off" mechanisms and (b) central metacontrast mechanisms in terminating visual response persistence in sustained channels.

Activity in the human primary motor cortex related to ipsilateral hand movements.

In two studies with positron emission tomography (PET), we found that somatosensory discrimination of length activated the ipsilateral MI, but somatosensory discrimination of shape did not. This occurred even though both tasks required the exclusive use of distal finger and hand movements which were also very similar in both tasks. The activation of the ipsilateral MI was correlated with activations of the premotor cortex in the other hemisphere, the prefrontal cortex and the posterior cingulate cortex, indicating that these areas together with the ipsilateral MI constitute a task-related active network.

Some shear facts and pure friction related to roughness discrimination and the cutaneous control of grasping.

The question of whether friction contributes to the perception of roughness has been overdebated and underinvestigated. A review of the psychophysical literature suggests that roughness and friction can be subjectively distinguished very effectively, although the same rapidly adapting Meissner corpuscles (RA1s) and slowly adapting Merkel receptors (SA1s) are stimulated by both stimuli. It appears that to achieve the subjective appreciation of roughness, the brain must learn to ignore variations in the speed of movement over the skin, the perpendicular force applied to the receptor surface, and the shear forces tangential to the skin generated by friction. Similarly, the subjective appreciation of slipperiness requires selective attention to tangential forces to the exclusion of speed, perpendicular force, and surface texture. A clearer picture is gradually emerging concerning the detection and appreciation of shear forces from investigations of the grasping and lifting of objects of different surfaces against the force of gravity. Although high shear forces provoke larger responses in almost all skin mechano-receptors, some neurons in both the sensory and motor cortex discharge more vigorously with smooth textures and lower coefficients of friction. Although populations of such neurons sensitive to smooth surfaces and low friction would be very useful in detecting both potential and real slips, just how the afferent signals are derived remains puzzling.
