In some examples, a system is configured to determine, using a neural network algorithm of a cerebral autoregulation model, a cerebral autoregulation status of the patient based at least in part on a blood pressure of the patient over a period of time and regional cerebral oxygen saturation of the patient over the period of time.

A biological information measurement system includes: a time measurement apparatus configured to transmit time information; a first measurement apparatus configured to measure brain neural activity of a subject, based on a biological signal detected from the subject; a first recording apparatus configured to record first data indicating a temporal change in the brain neural activity measured by the first measurement apparatus, in association with the time information received from the time measurement apparatus; an image capturing apparatus configured to capture an image of the subject; and a second recording apparatus configured to record second data indicating a temporal change in a posture of the subject, the posture identified based on the image captured by the image capturing apparatus, in association with the time information received from the time measurement apparatus.

A wearable apparatus for display glasses is provided. According to certain embodiments, the apparatus includes a display configured to provide a display of information that includes at least two options for selection. The apparatus further includes an electromyograph device and a processor. The electromyograph device is configured to track muscle activity of a wearer of the display glasses. The processor is configured to determine a plurality of events based on the muscle activity. The plurality of events are associated with at least one of types of the muscle activity, occurring numbers of the types of the muscle activity, or occurring time of the types of the muscle activity. One of the at least two options is identified based on the plurality of events.

A system and related devices for continuous and real-time monitoring and detection of head impact and corresponding trauma. The system may include a passive sensor mounted to a subject's tooth using dental hardware or adhesive so as to harness the firm coupling between the subject's tooth and cranium. With such firm coupling established, the impact data measured by the tooth-mounted sensor can be manipulated, through the use of a transfer function, by external processors to determine and communicate the impact experienced by the subject's head. The system is configured for use with an external power source whereby the passive tooth-mounted sensor is activated by means of a wireless transfer circuit such as an inductive power transfer circuit or an ultrasound power transfer circuit. The wireless activation of the powerless interior sensor system provides compatibility with multiple external power configurations, thereby enabling efficacious and continuous monitoring of the subject.

In various embodiments, the present invention teaches systems and methods for using T1-weighted black-blood MR imaging, with which a CVT can be well isolated from the surrounding tissues due to the signal suppression of flowing blood. In some embodiments, the invention teaches using black-blood imaging (3D variable-flip-angle turbo spin-echo acquisition) to directly visualize thrombi. In certain embodiments, the invention teaches using T1 weighted image contrast and isotropic sub-millimeter spatial resolution for accurate detection and staging of thrombi. In various embodiments, the invention allows for the detection of chronic thrombosis recanalization.

A method is described for determining an optimal placement location for an auditory brainstem implant (ABI) electrode array. A cochlear implant (CI) electrode array is inserted into a patient cochlea, and the ABI electrode array is initially placed at an initial placement location on a patient brainstem. The optimal placement location for the ABI electrode array is then determined by, for multiple electrode contacts on the ABI electrode array: i. selecting a specific electrode contact, ii. delivering a stimulation signal to the selected electrode contact, iii. sensing an efferent nerve signal from the stimulation signal using the electrode contacts of the CI electrode array, and iv. determining a maximum response location in the patient cochlea where a largest efferent nerve signal is sensed. The ABI electrode array is then repositioned to the optimal placement location.

A novel method to noninvasively measure intracranial pressure (ICP) and more generally brain elasticity is disclosed. ICP is determined using an algorithm coupled on a simulated artificial neural network (SANN) that calculates ICP based on a determination of a set of interacted ultrasound signals (IUSs) generated from multiple ultrasound pulses. The methods and systems of the present invention are capable of rapidly determining ICP without manual review of EPG waves by a technician.

Provided herein are methods and systems for high-resolution, cerebrospinal fluid-suppressed T2*-weighted magnetic resonance imaging of cortical lesions.

Equipment for applying active elements to a cranium of a patient comprises a support and a plurality of active elements, wherein the support comprises a means of connection with a patient and means for positioning the active elements in order to excite N+M zones of the cranium, the N+M zones comprising the zones VG.sub.19, VG.sub.20, VG.sub.21, C.sub.4, C.sub.5R, C.sub.5L, C.sub.6R and C.sub.6L, N and M being two integer numbers, N being a number between 2 and 8, M being less than N/2.

An access port or retractor tube provides access through tissue to a surgical site or field, such as at the brain or spine, in a minimally invasive manner. The access port permits a user to clearly view and access the surgical field, including areas medial thereto, in a minimally invasive manner by dilating or separating tissue rather than cutting tissue. Neuro monitoring and neuro navigation are tools essential to neuro surgery to protect vital and eloquent tissues. Combining navigation and monitoring into the access ports/retractor tubes would enable the surgeon to be more precise and efficient during minimally invasive procedures while still being maximally effective in protecting non operative tissues.
