Abstract: A system and methods for monitoring and controlling a mental state of a subject are provided. In some aspects, a method includes receiving physiological and behavioral data acquired using the plurality of sensors while the subject is performing a task, and applying, using the data, a state-space framework to determine a plurality of decoder parameters correlating brain activity and behavior with a mental state of the subject. The method also includes identifying the mental state of the subject using the decoder parameters, and generating a report indicating the mental state of the subject. In some aspects, the method further includes generating, based on the identified mental state, a brain stimulation to treat a brain condition of the subject.

Abstract: The invention generally relates to methods of stimulating tissue based upon filtering properties of the tissue. In certain aspects, the invention provides methods for stimulating tissue that involve analyzing at least one filtering property of a region of at least one tissue, and providing a dose of energy to the at least one region of tissue based upon results of the analyzing step.

Abstract: The invention generally relates to methods for guiding physical therapy to a subject. In certain embodiments, methods of the invention involve providing stimulation to a subject's central nervous system to modulate one or more signals sent to or from a plurality of target regions of the subject. Methods of the invention further involve assessing the response of the plurality of target regions to the stimulation to determine if there is a differential response among the target regions to the stimulation, and providing focused physical therapy to at least one of the target regions based on the assessment of the response of the plurality of peripheral target regions to the stimulation.

Abstract: An apparatus for generating focused currents in biological tissue is provided. The apparatus comprises an electric source capable of generating an electric field across a region of tissue and means for altering the permittivity of the tissue relative to the electric field, whereby a displacement current is generated.
