Investigating the Neural Control of Movement by Interfacing Spinal Motor Neurons

Fondazione Santa Lucia Irccs - Centro Congressi

Il Seminario sarà tenuto dal Prof. Dario Farina, Ordinario di Ingegneria per la Neuroriabilitazione presso il Dipartimento di Bioingegneria dell'Imperial College London con precedenti incarichi come Professore Ordinario presso l'Università di Aalborg (Danimarca) e l'Università di Gottinga (Germania), dove ha fondato e diretto il Dipartimento di Sistemi neuroriabilitativi. Tra i suoi numerosi riconoscimenti, l'IEEE Engineering in Medicine and Biology Society Early Career Achievement Award e l'Advanced Grant dell'European Research Council. L'attività di ricerca del Prof. Farina si concentra sul processamento di segnali biomedici, tecnologie per la neuroriabilitzione e il controllo neurale del movimento.

Abstract

The talk will overview the technology for motor neuron interfacing, the motor neuron population view of muscle control, as well as the potential of motor neuron recording technology for man-machine interfacing. Alpha motor neurons receive synaptic input that they convert into the ultimate neural code of movement - the neural drive to muscles. The study of the behavior of motor neurons provides a window into the neural processing of movement. Recently, the interfacing (bioelectrodes) and processing methods for identifying the output of motor neuron pools from interference electromyogram (EMG) signals have been advanced substantially. In the past decade, these methods have indeed allowed for the first time the monitoring of the behavior of tens to hundreds of motor neurons concurrently, with minimally invasive or non-invasive methods. This new population analysis has opened new perspectives in the study of the neural control of movement. Recent physiological investigations using these technologies challenge classic views on force generation, such as the functional meaning of motor neuron synchronization, the mechanisms that limit steadiness in precise tasks, and the impact of high frequency neural oscillations in force modulation.
