Abstract: The present invention relates to methods and devices for determining the state of a neural system. In one embodiment, a plurality of stimuli to the system can be delivered to the system, and then the resulting respective responses can be analyzed to determine whether the system state is static, or whether it is undergoing dynamic changes. In another aspect of the invention, a single stimulus having a plurality of components can be administered, and the responses to each component can be contrasted and compared to determine the state of the neural system. In each case, this information can be used to predict the occurrence of neural perturbations or episodes associated with a change in the state of the neural system.

Abstract: The present invention provides devices and methods for modulating the properties and propagation of traveling waves of electrical activity in neural systems. Such modulation is useful for a variety of purposes, including the control and containment of epileptic seizure activity, for treating mental disorders, movement disorders, sleep disorders, pain, and other disturbances and illnesses associated with neural systems. In addition, the devices can be used to modulate sensory and other stimuli experienced by a neural system, as well as any other normal neural activity. Neural prosthetic devices incorporating the methods of the present application have a wide range of applications and use in medicine, psychiatry, behavioral psychology, research, and other disciplines that address and treat disturbances in neural systems.
