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/.
