In this study we propose to quantify the peripheral vibrissal system specificity through its neuronal responses. Receiver operating characteristics (ROC) curve analyses were used, which required the implementation of a binary classifier (artificial neural network) trained to identify the applied stimulus. The training phase consisted of the observation of a predetermined amount of vibrissal sweeps belonging to two experimental situations. Our results suggest that specificity of peripheral vibrissal system, quantified through neuronal responses, varies according to the perceived stimulus, and that it can be quantified through an ROC curve analysis. Furthermore we found that such specificity can be determined by an binary classifier after observing at most 5 vibrissal sweeps.
