Abstract: One of the main challenges in upper limb neuroprosthetics is to implement realistic tactile feedback. An emerging trend for tactile feedback is to mimic the neuronal activity of biological mechanoreceptors in order to enable natural learning of feedback. We implemented real-time neuromorphic artificial touch by injecting the raw output of a biomimetic tactile sensor into an Izhikevich neuronal model emulating the firing behavior of mechanoreceptors. The resulting neuromorphic spike trains were able to classify naturalistic textures with high accuracy by mean of Victor Purpura metrics. Crucially, we found that the decoding performance based on neuromorphic spike trains was robust for a broad range of sensing conditions. Being able to categorize naturalistic textures in different sensing conditions, these neurorobotic results pave the way to the use of neuromorphic tactile sensors in future real-life neuroprosthetic applications.

Reading Group Seminars: The Reading Group Seminars (RGS) are organized within an open community of researchers interested in applying up to date mathematical modeling and data analysis approaches to the study of biological systems. The RGS take place at the Math. Department in Milan (via Saldini). Initiatives and updates are published on the website: http://rgs.mat.unimi.it/.
