The invention features methods and apparatus for enhancing neurophysiology performance, such as sensorimotor control and neuroplasticity. A preferred method involves inputting bias signals to sensory cells of a subject, thereby improving sensory cell function, while the subject is performing a predefined physical activity. A system used to practice the method of the invention includes a wearable device (500) to which is secured at least one repositionable signal input device (510) and a signal generator (514) that is communicatively coupled to the signal input devices.
