1. A system comprising: an input to couple to a sensor to detect a neuro-physiological state of a student; a configurator to receive input regarding training objective functions and to modify control algorithms and system parameters in accordance with a selected training objective function; and a controller coupled to the input to implement the control algorithms and provide a communication if the student is outside a desired neuro-physiological state consistent with a desired learning zone and to provide a lesson intensity control signal as a function of the provided communication, sensed neuro-physiological state and selected training objective function.
