Craniode
20230414157 · 2023-12-28 ·

A craniode is positioned in an intra-osseous fashion, namely partly or wholly within the bone of the skull, without penetrating the interior of the skull, while also being positioned below the scalp. A craniode can be used to sense electrical signals from a brain, to electrically stimulate the brain, to emit light signals to the brain, to detect light signals from the brain, to perform functional near infrared spectroscopy on the brain, and to perform photobiomodulation on the brain; and can, for example, provide the ability to perform these procedures in daily life. To resolve the problem of connectivity, each craniode can be connected, or can be equipped with features that make it connectable, to a subcutaneous cable, thus enabling the long-term usage of the craniode in real-life settings; or, active electrodes can be used to transmit signals wirelessly. Transcutaneous and sub-scalp implantation techniques are also provided.

Systems and Methods for Artifact Reduction in Recordings of Neural Activity
20210204883 · 2021-07-08 ·

Disclosed are systems and methods for reducing artifacts in neural activity readings. Electrical readings may be acquired using EEG electrodes secured to a subject. A high-pass or band-pass filter may be applied to the electrical readings to favor frequencies more associated with neurogenic potentials as opposed to myogenic potentials. Independent component analysis (ICA) may be applied to the filtered electrical readings. Selected components in each iteration may be pruned to produce reduced-artifact electrical readings, and the reduced-artifact electrical readings may be presented for further review and analysis.

REAL-TIME NEURAL SPIKE DETECTION

A method is described for real-time detecting and classifying of a characteristic signal, such as a neural spike, and forwarding information for further processing if it meets certain criteria. A system (e.g., an on-chip system implanted in a subject's cranium with limited processing power) receives an electrical biological signal. The system filters the signal to generate a filtered signal and fits the filtered signal to a model. The system identifies a set of fit values based on the model, the set of fit values comprising a plurality of sample amplitude values and a respective plurality of time values. Based on the fit values, the system computes a set of characteristic values. The system compares the characteristic values to a corresponding set of threshold values. Based on the comparison, the system determines whether the received biological signal corresponds to a neural spike and, if a spike is detected, forwards on information.
