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.

Abstract: The present invention provides methods and devices for performing electroencephalographic (EEG) phase dependent brain imaging using evoked and event related potentials (EP, ERP) or other forms of brain imaging including functional magnetic resonance imaging (fMRI) and magnetic encephalography (MEG). The methods and devices can be used for a variety of purposes, including for the study of normal and pathological cognitive function, and for the diagnosis and prognosis of neurological and sleep disorders.

Abstract: A system and methodology for conducting electronic-based transactions. In one aspect, a transaction is conducted using real-time user interaction including recording data representing a specific purpose (or other information) associated with transactions, voice-print authentication of user(s), and/or recording spoken voice of user(s). In another aspect, a system for conducting electronic-based transactions includes a payment processor with input logic, decision logic and output logic. The input logic communicates with a transaction terminal to receive transaction request data (transaction amount and transaction descriptor data). The decision logic selectively authorizes the transaction based upon analysis of the received transaction amount and transaction descriptor data in conjunction with balance information and at least one usage restriction for an account. The output logic generates a status message for communication back to the transaction terminal.

Abstract: A method and system are disclosed for conducting a financial transaction using a communication device. In accordance with exemplary embodiments, the system includes a communication device for transmitting user identification information and a unit identification number that is associated with a financial transaction device that is contacted via the communication device. The system includes a financial transaction system for receiving the user identification information and the unit identification number from the communication device. The financial transaction system is contacted using an access calling number. The financial transaction system is configured to transmit financial information associated with the user to the financial transaction device associated with the unit identification number.
