A quantitative metric indicative of the pain experienced by the subject is computed by processing the identified modulations in the acquired electrophysiological data.Type: ApplicationFiled: August 28, 2013Publication date: March 6, 2014Inventors: Bin He, Huishi Zhang

Publication number: 20140058241Abstract: A method and apparatus for neurological assessment are provided. More specifically, the present invention relates to assessing central nervous system (CNS) function or the change in CNS function. The system (10) includes a monitoring device (20) for monitoring the brain activity of a patient (5) in response to one or more stimuli provided to the patient. Data from the monitoring device (20) is analyzed to determine a measure of CNS condition for the patient. The patient data can be compared with similar data obtained for the patient at a different time to aid a medical professional in the diagnosis or treatment of a neurological or neurodegenerative condition.Type: ApplicationFiled: August 21, 2013Publication date: February 27, 2014Inventors: Ross Apparies, Mark Pflieger

Publication number: 20140058528Abstract: A noninvasive brain computer interface (BCI) system includes an electroencephalography (EEG) electrode array configured to acquire EEG signals generated by a subject. The subject observes movement of a stimulus. A computer is coupled to the EEG electrode array and configured to collected and process the acquired EEG signals. A decoding algorithm is used that analyzes low-frequency (delta band) brain waves in the time domain to continuously decode neural activity associated with the observed movement.Type: ApplicationFiled: May 5, 2011Publication date: February 27, 2014Applicant: UNIVERSITY OF MARYLAND, COLLEGE PARKInventors: Jose L. Contreras-Vidal, Trent J. Bradberry, Rodolphe J. Gentili, Harshavardhan Agashe

Patent number: 8655428Abstract: Efficient and effective mechanisms for collecting electroencephalography (EEG) data are provided to synchronize neuro-response data collection with stimulus material presentation for in situ engagement monitoring and tracking. An EEG headset includes multiple point electrodes individually isolated and amplified. In some examples, a stimulus material presentation mechanism includes a clock source and a clock transmitter. The clock transmitter sends clock signals to a neuro-response data collection mechanism to allow synchronization of neuro-response data collected with stimulus presentation events. The EEG headset can be configured to perform processing while supporting both continuous input and output.Type: GrantFiled: May 12, 2010Date of Patent: February 18, 2014Assignee: The Nielsen Company (US), LLCInventors: Anantha Pradeep, Robert T. Knight, Ramachandran Gurumoorthy
