Closed-Loop Systems intended for efficient diagnosis and treatment of neurodegenerative diseases are targets to mimic brain regular operation. Consequently, neuromorphic based learning techniques are the heart parts of emerging control units to be embedded in proposed Neuromodulation Systems. This talk covers the implementation of custom devices intended for the diagnosis, treatment, and prediction of health conditions. It includes signal processing methods, custom integrated circuits and subsequent use to implement wearable and implantable bioelectronic closed-loop systems for brain interfaces. These methods deal with multidimensional design challenges such as efficient power management, low-power and high-data rate wireless communication methods, small volume devices, reliable wearable, and implantable systems. In these neuromodulation applications, priority could be given to non-invasive approaches, however for some healthcare dysfunctions, wearable systems can not apply, implantable devices should be used. Also, optoelectronic methods are becoming the winning approaches to build proposed advanced closed-loop systems for both non-invasive nanoimaging, and transcranial stimulation. Case studies include several applications such as epilepsy, vision, addictions.
