Abstract: The clinical diagnosis and monitoring of patients with neurological conditions may be established through behavioral examinations, assessments or evaluations, or neuroimaging scans. The system and methods described herein diagnose the cognitive function of a subject by measuring the neural response of the subject to one or more naturalistic sensory stimuli. The system measures the subject's sensory evoked response to the naturalistic sensory stimuli by computing the statistical comparison between the subject's neural signal and either the raw stimulus signal or the stimulus' signal envelope. A latency value, or other signal feature, is extracted from the subject's sensory evoked response and a diagnosis of the subject's cognitive function is then made based on the identified latency value or other extracted signal feature.

Abstract: A method for selective activation of central thalamus fibers in a subject is disclosed. The method involves providing one or more electrodes each with one or more contacts. The one or more electrodes are positioned in the subject’s central thalamus fibers. An electrical stimulus is applied to the positioned one or more electrodes to selectively activate the central thalamus fibers of the subject. The positioning and applying are carried out to maximize central lateral nucleus and medial dorsal tegmental tract fiber pathway activation in the subject and to minimize central median parafascicularis fiber pathway activation in the subject. Methods, devices, and computer readable media for surgical planning involving selective activation of central thalamus fibers in a subject are also disclosed.

Abstract: The present disclosure is directed to methods for improving a wakeful function in a subject suffering from an acquired cognitive deficiency by administering to the subject an effective amount of an upregulator of GABAB signaling, thereby improving the wakeful function in the subject. Another aspect of the disclosure us directed to methods for improving a wakeful function in a subject suffering from an acquired cognitive deficiency by administering to the subject an effective amount of an upregulator of GABAB signaling at night, in combination with administering an anterior-forebrain stimulating therapy when the subject is awake, thereby improving the wakeful function in the subject.

Abstract: The system and methods described herein determine a subject's indication of attention to a first and a second sensory stimuli. The system determines a sensory evoked response of the subject by calculating the statistical relationship between the subject's neural response to the stimuli and a signal feature of the first and the second sensory stimuli. A magnitude value of the sensory evoked response is extracted to determine whether the subject attended-to or ignored the sensory stimuli. The system will select the stimuli that elicited the greater indication of attention, and then trigger further processing by a computer. Such processing can include selecting future content for improving safety warnings, educational materials, or advertisements or further processing can include controlling and navigating a brain computer user interface.

Abstract: The present invention relates to a method to control a thalamic projecting fiber in a subject. This method involves providing a subject having a first stimulator and a second stimulator implanted in the subject's central thalamus. A stimulus signal generator is provided which is coupled to the first and second stimulators. Separate stimulus signals are provided from the stimulus signal generator to the first and second stimulators under conditions effective to control the thalamic projecting fiber in the subject. Also disclosed is an apparatus for deep brain stimulation.

Abstract: The disclosure relates to methods and compositions for preventing or treating cognitive dysfunction. The methods comprise administering an effective amount of an aromatic-cationic peptide to subjects in need thereof. Specifically, the aromatic-cationic peptide has the formula D-Arg-2?,6?-Dmt-Lys-Phe-NH2, and the cognitive dysfunction is associated with a reduced cerebral metabolic rate of oxygen (CMRO).

Abstract: A system for treating medical conditions by neuromodulation of one or more target sites in the nervous system. In certain embodiments, at least one of the target sites is the medial thalamic region, including the intralaminar nucleus and the adjacent white and grey matter. In certain embodiments, where there is more than one target site, the other target sites is elsewhere in the nervous system, including the globus pallidus interna, subthalamic nucleus, corpus callosum, cerebellum, cerebral cortex (including the premotor cortex, motor cortex, and sensory cortex), ventral striatum, lateral thalamus, substantia nigra, and pedunculopontine nuclei. The medical conditions include movement disorders or improvement of movement function, stroke, neuropsychiatric or neuropsychologic disorders, neurodevelopmental disorders, and pain. Methods for treating medical conditions by neuromodulation of the intralaminar nuclei either alone or in combination with another target site(s) is also provided.

Abstract: A canonical decomposition (CD) method that includes building a multi-variate linear autoregressive (“MLAR”) model from an original data set or from a reduced set derived by data reduction methods from the original data set. The MLAR analysis is followed by seeking a coordinate transformation of the MLAR model to obtain the best possible match with one or more canonical forms representing relationships among components. For multi-variate data with a truly hierarchical structure, CD accurately extracts the underlying sources of the system.
