A method for fabricating electrodes sized and dimensioned to record, measure, and/or stimulate very fine nerve structures (e.g., microscale or less) is described herein. The method can include securing a tip of an electrode, comprising a conductor substantially encased by an insulator, to a proximal portion of an inserter. The electrode can be wound around a proximal portion of the inserter and a portion of the electrode can be secured to a distal portion of the inserter. A tension in the electrode can be maintained during the winding to keep the electrode in place during the winding.

A method for autonomous segmentation of three-dimensional nervous system structures from raw medical images, the method including: receiving a 3D scan volume with a set of medical scan images of a region of the anatomy; autonomously processing the set of medical scan images to perform segmentation of a bony structure of the anatomy to obtain bony structure segmentation data; autonomously processing a subsection of the 3D scan volume as a 3D region of interest by combining the raw medical scan images and the bony structure segmentation data, wherein the 3D ROI contains a subvolume of the bony structure with a portion of surrounding tissues, including the nervous system structure; autonomously processing the ROI to determine the 3D shape, location, and size of the nervous system structures by means of a pre-trained convolutional neural network (CNN).

In order to estimate a movement command that a central nervous system is to select to implement a desired movement based on three feature amounts under the concepts of an antagonistic muscle ratio and an antagonistic muscle sum and based on a musculoskeletal model, a movement analysis apparatus includes: a myoelectric potential measurement unit to measure a myoelectric potential of a person who performs a movement; a movement measurement unit to measure a body movement; and a stiffness-ellipse calculation unit, an equilibrium-point calculation unit and a muscle synergy calculation unit to calculate, from measurement information obtained at the measurement units, feature amounts of a stiffness ellipse, an equilibrium point, and a muscle synergy that are base vectors describing the equilibrium point at an operating point based on a musculoskeletal model.

An electrode assembly includes a needle and a conductive thread electrode carried in a slot on the surface of the needle. The needle pushes the thread electrode into the body and leaves it in place when the needle is removed. The needle is secured in a housing in a retracted position and moved to an extended position by a latch. In the extended position, one end of the needle remains in the housing and the other end extends from the housing. The needle is attached to a spring inside the housing and is moved by the latch against the urging of the spring to the extended position and locked in place. A protective cover is applied over the needle while extended and removed to insert the needle into the body of a patient.

A cognitive/multisensory stimulation system simulates real sports action/job task scenarios for assessing, profiling, practicing, improving or rehabilitating cognitive function performance of athletes or individuals. Cognitive function improvement can be provided by: establishing with a subject a sensory semantic language for relating a number of sensory signals to corresponding possible actions, the sensory semantic language being essentially new to the subject; instructing the athlete to perform an task involving sport/job skills; providing to the subject during the task sensory signals requiring rapid discernment by the subject of the semantic meaning of the sensory signal to correctly chose one possible action; and determining whether the subject correctly responds to the selected sensory signal during the task; obtaining a cognitive-sensor reaction-time map over a visual field of the subject; and repeating the steps over multiple repeated tasks using selectively randomized sensory signals selected to progressively restore the cognitive-sensor reaction-time map a normal profile.

An emotion identification device includes: a first detection unit which detects a central nervous system reaction of a user; a second detection unit which detects an autonomic nervous system reaction of the user; and an identification unit which identifies aggressiveness in anger of the user based on the central nervous system reaction and the autonomic nervous system reaction.

Systems and methods combine virtual reality (VR), eye-tracking (ET), and motion sensors on limbs such as hands and feet to evaluate the changes of cognitive and motor abilities in both healthy and non-healthy persons using well-defined exercises. The application of VR and ET in cognitive exercises with motion sensors can improve the efficacy of the intervention and the ability to quantify cognitive and motor capabilities, enhancing the effectiveness of the training on a person.

A method for treating vestibular impairment, comprising: (a) providing a virtual reality apparatus comprising: a headset; a smartphone having a computer processor, a camera, and a display screen; a case holding the smartphone attaching to the headset; a first optical arrangement, for focusing a field of view of the camera on the user's eye; a second optical arrangement for viewing the display screen; and an application and the processor adapted to display a stimulation exercise on the screen; wherein, the application records movements of the eye, during the exercise, using the camera; wherein the application determines user response competence to the exercise, based upon the movements; and accordingly modifies exercise degree of difficulty; (b) placing the headset on the user's head; (c) focusing the field of view onto the eye; (d) displaying the exercise; and (e) recording eye movements, using the camera.

An implantable nerve stimulator is implanted in a patient near a nerve target. The implantable nerve stimulator has a plurality of electrodes through which stimulation is provided to the nerve target. The relative location of the nerve target and the electrodes may be determined by applying stimulation to the nerves via each of the electrodes, determining an effect of the stimulation for each of the electrodes, and mapping a location of the nerve relative to the electrodes based on the effect of the stimulation for each of the electrodes.

The disclosed system enables monitoring of user's biological indicators for signs of impairment or disease. The system obtains a permission from a user to access a biological indicator. The system obtains a history of the biological indicator associated with the user, where the biological indicator includes movement associated with the user, a voice associated with the user, or an appearance associated with the user. The system obtains a symptom indicating an undesirable state of the user, where the symptom includes a musculoskeletal affliction. The system monitors the biological indicator of user. The system detects an anomaly in the biological indicator by comparing the biological indicator with the history of the biological indicator. The system determines whether the anomaly indicates the undesirable state of the user. Upon determining that the anomaly indicates the undesirable state of the user, the system provides a notification.
