Abstract: A device and system for real-time visualization of the electrophysiologic activity of a brain, particularly at the cortical surface. The neural device can acquire, process, and display high-spatiotemporal-resolution electrophysiologic data in real-time across entire electrode arrays spanning many thousands of electrodes over identified anatomic regions. The system is compatible with thin-film cortical surface electrodes that record from neural tissues without damaging those tissues. The system can be used to guide diagnostic and therapeutic actions with high precision, and also provides the basis for a brain-computer interface.

Abstract: A neuronavigation system including a microelectrode array configured to be placed on a brain surface and record neural signals, the microelectrode array comprising a fiducial, and a computer system configured to register a position of the microelectrode array with respect to the brain surface based on the fiducial, receive neural signals from the microelectrode array, and generate a visualization overlaying the received neural signals on a brain image based on the registered position of the microelectrode array for display during a neurosurgical procedure. The neuronavigation system can be used in a variety of different neurosurgical applications, including implanting neural interfaces or locating particular cortical regions.

Abstract: A system for detecting a neurological state of a brain of a patient is disclosed. The system comprises one or more recording arrays, a database, and a processor. The recording arrays comprise a plurality of recording electrodes having a diameter of less than about 1 mm and spaced by less than about 1 mm, and are configured to be minimally invasively inserted to the brain to record electrical signals from a target recording site. The database stores electrophysiological data relating to known electrophysiological signatures associated with neurological states. The processor is configured to receive recorded signals from the recording arrays, access the electrophysiological data from the database, identify electrophysiological signatures in the recorded signals based on the electrophysiological data, and determine the neurological state of the brain based on the identified electrophysiological signatures.

Abstract: A method, apparatus, or system for reducing gait asymmetry is disclosed. The method, apparatus, or system may include measuring one or more gait parameters of an individual; calculating a joint metric based on the measured one or more gait parameters; and signaling an adjustment of an amount of one or more perturbation techniques based on the joint metric for reducing asymmetry in a gait pattern of the individual. The one or more perturbation techniques include asymmetric rhythmic auditory cueing making a first audible cue with a first cue duration for one leg of the individual and a second audible cue with a second cue duration for another leg of the individual. Here, the first cue duration is different from the second cue duration. Other aspects, embodiments, and features are also claimed and described.

Abstract: A method, apparatus, or system for modifying and assessing gait asymmetry is disclosed. The method, apparatus, or system may include measuring a first baseline step time for a first leg of an individual and a second baseline step time for a second leg of the individual and determining a first target step time for the first leg and a second target step time for the second leg. The first target step time can be different from the second target step time. The method may further include generating a series of auditory cues comprising a first cue duration corresponding to the first target step time and a second cue duration corresponding to the second target step time for synchronizing the first baseline step time and the second baseline step time with the first target step time and the second target step time, respectively. Other aspects, embodiments, and features are also claimed and described.
