Differential width discrimination task for active and passive tactile discrimination in humans.

ABSTRACT: The neurophysiological basis of width discrimination has been extensively studied in rodents and has shown that active and passive tactile discrimination engage fundamentally different neural networks. Although previous studies have analyzed active and passive tactile processing in humans, little is known about the neurophysiological basis of width discrimination in humans. Here we present a width discrimination task for humans that reproduces the main features of the width discrimination task previously developed for rodents. The task required subjects to actively or passively sample two movable bars forming a "narrow" or "wide" aperture. Subjects were then required to press one of two buttons to indicate if the bar width was "narrow" or "wide". Behavioral testing showed that subjects wer
