Results of the calibration procedure to set-up the Sensory Interface using different data sets.

<p>The goal of the calibration procedure is to define the “sensory regions” by partitioning the position space of the controlled device. (A) from left to right: i) a representation of the evoked spike activity, ii) a color-coded scheme of the recorded spike activity, iii) a graphical representation in the 2D domain of the results of the multidimensional scaling of the distance metric for each spike train, iv) the sensory regions obtained using a nearest neighbor algorithm. We tested this procedure also by using three different stimulation intensities (B), a combination of the stimulation electrodes obtained by co-stimulating neighboring electrodes (C) and by combining the co-stimulation with three stimulus intensities (D).</p>
