Abstract: Provided are systems, methods, and devices for brain stimulation and monitoring. Brain stimulation may be provided to enhance slow wave and spindle synchrony. Such stimulation may provide increased memory consolidation. Furthermore, brain stimulation modalities may provide enhanced sleep and awakening. For example, transcranial direct current stimulation of the brain stimulation may enhance sleep quality. Moreover, one or more markers characterizing unconsciousness are may be identified based on changes in measured power densities or spectra. Further still, the above described modalities of brain stimulation may be implemented in an open-loop or closed loop manner. Brain state parameters may be generated for building models of the brain based on determined synchrony patterns between slow waves and spindles. The models may be used to determine a mediation procedure for adjusting the intensity of slow wave oscillations to enhance slow wave and spindle synchrony.

Abstract: Electrical non-invasive brain stimulation (NIBS) delivers weak electrical currents to the brain via electrodes that are affixed to the scalp. NIBS can excite or inhibit the brain in areas that are impacted by that electrical current during and for a short time following stimulation. Electrical NIBS can be used to change brain structure in terms of increasing white matter integrity as measured by diffusion tensor imaging. Together the electrical NIBS can induce changes in brain structure and function. The present methods and devices are adaptable to and configurable for facilitating the enhancement of brain performance, and the treatment of neurological diseases and tissues. The present methods and devices are advantageously designed to utilize modern electrodes deployed with, inter alia, various spatial arrangements, polarities, and current strengths to target brain areas or networks to thereby enhance performance or deliver therapeutic interventions.
