Bringing sensation to prosthetic hands-chronic assessment of implanted thin-film electrodes in humans

Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Ivo Strauss, Giacomo Valle

Direct stimulation of peripheral nerves with implantable electrodes successfully provided sensory feedback to amputees while using hand prostheses. Longevity of the electrodes is key to success, which we have improved for the polyimide-based transverse int ...

A Software Tool for the Real-Time in Vivo Evaluation of Neural Electrodes' Selectivity

Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Ivo Strauss, Daniela De Luca

High neural selectivity is an important indicator of how well a neural electrode will perform in a clinical setup. Among other factors, neural selectivity of an electrode strongly depends on its implant location. Today, the neural selectivity is evaluated ...

Brain reactions to the use of sensorized hand prosthesis in amputees

Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Edoardo D'Anna, Ivo Strauss, Giacomo Valle, Fabrizio Vecchio, Francesco Iberite

Objective We investigated for the first time the presence of chronic changes in the functional organization of sensorimotor brain areas induced by prolonged training with a bidirectional hand prosthesis. Methods A multimodal neurophysiological and neuroima ...

Cortical plasticity after hand prostheses use: Is the hypothesis of deafferented cortex "invasion" always true?

Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Edoardo D'Anna, Ivo Strauss, Pablo Garcia del Valle, Giacomo Valle, Francesco Iberite

Objective: To study motor cortex plasticity after a period of training with a new prototype of bidirectional hand prosthesis in three left trans-radial amputees, correlating these changes with the modification of Phantom Limb Pain (PLP) in the same period. ...

Morphological Neural Computation Restores Discrimination of Naturalistic Textures in Trans-radial Amputees

Silvestro Micera, Francesco Maria Petrini, Simone Romeni, Ivo Strauss, Giacomo Valle, Fabrizio Vecchio, Roberto Puddu

Humans rely on their sense of touch to interact with the environment. Thus, restoring lost tactile sensory capabilities in amputees would advance their quality of life. In particular, texture discrimination is an important component for the interaction wit ...

Decoding of grasping tasks from intraneural recordings in trans-radial amputee

Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Ivo Strauss, Giacomo Valle

Objective. A major challenge in neuroprosthetics is the restoration of sensory-motor hand functions in upper-limb amputees. Neuroprostheses based on the direct re-connection of the peripheral nerves may be an interesting approach for re-establishing the na ...

Sensitivity to temporal parameters of intraneural tactile sensory feedback

Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Edoardo D'Anna, Ivo Strauss, Giacomo Valle

Background Recent studies have shown that neural stimulation can be used to provide artificial sensory feedback to amputees eliciting sensations referred on the amputated hand. The temporal properties of the neural stimulation modulate aspects of evoked se ...
