Title: Closed-loop Neuromorphic Systems-on-chips for Early Diagnosis and Prediction of Brain Diseases

Abstract: Closed-Loop neuromodulation based medical devices intended for efficient diagnosis, treatment and prediction of neurodegenerative diseases are targets to mimic brain regular operation. Consequently, artificial intelligence-based learning techniques are the central parts of these emerging control units to be embedded in proposed neuromodulation systems. This talk covers the implementation of wearable and implantable medical devices based on custom neuromorphic system-on-chip (SoC) integrated platforms. These devices include signal processing methods, design and tests of SoCs and system assembly of bioelectronic closed-loop systems for brain interfaces.

These methods deal with multidimensional design challenges such as efficient power management, very low-power and high-data rate wireless communication methods, and reliable systems. In these neuromodulation applications, priority could be given to non-invasive approaches, however for some healthcare dysfunctions, wearable systems can not apply. Consequently, implantable devices should be used. Also, optoelectronic methods are used to build efficient devices for both non-invasive nanoimaging, and transcranial stimulation. Case studies include several applications such as epilepsy, vision, addictions, and early and fast viruses’ detection.
