Instead of thinking of individual groups of
afferents working separately to process different components of the sense of touch, Bensmaia said we should think of all of them working in concert, much like individual musicians in a band to create its overall sound.

During a TT, pacing strategy is regulated in a complex anticipatory system that monitors
afferent feedback from various physiological systems, and then regulates the
work rate so that potentially limiting changes do not occur before the endpoint of exercise is reached.
In contrast, if the initial
work rate and RPE are the result of
afferent feedback, then differences in
work rate would be expected at the onset of exercise, as soon as differences between conditions are detected.
Another limitation concerns the measurement of the physiological
afferents that are proposed to regulate
work rate through this feedback system.
The
work of Kremkow and colleagues indicates that the organization of all maps originates from the same principle: an arrangement of thalamic
afferents that minimizes differences in spatial position, eye input and light / dark polarity among neighboring cortical neurons.
Afferents to the visual wulst were mapped by stereotactic iontophoretic application (4 µA positive current, 7 sec on / off, duration: 20 — 30 min) of biotinylated dextran amin (BDA,
working dilution: 10 % in phosphate buffered saline, PBS; Molecular Probes Europe BV, Leiden, The Netherlands) into Cluster N or into medial parts of the visual Wulst.
