Embodiment Construction

[0079] As used herein, "reference electrode" refers to a contact (preferably also provided by made of metal). For example, a reference electrode may allow comparison of brain activity detected by multiple recording elements.

[0080] As used herein, "ground electrode" refers to a recording element used to provide information about globally recorded electrical signals derived from non-physiological sources such as local electrical equipment and thus allow common-mode rejection of such non-physiological signals.

[0081] As used herein, a "recording element" is a contact capable of detecting electrical brain activity.

[0082] As used herein, "subgaleal space" refers to the anatomical compartment of the scalp that lies beneath the epidermis and galeal membrane (the fascial layer of the scalp) and the periosteum and bone of the skull. The subgaleal space is a naturally occurring avascular area that can be easily accessed and traversed with specialized tools without significant ...

Abstract

The invention encompasses systems and methods that allow a clinician who is untrained in the art of electroencephalography to insert and functionalize unitized intracranial electrode arrays at the bedside that, by specific design, position ground and reference electrodes in electrically "quiet" locations to record durable, high-fidelity intracortical EEG.

Description

technical field [0001] The present invention encompasses systems and methods that allow untrained clinicians in the field of electroencephalography to insert and functionalize sets of intracranial electrode arrays at the bedside that, by specific design, connect ground and Reference electrodes are positioned at electrically "quiet" locations to record long-lasting, high-fidelity intracortical EEG. Background technique [0002] Electroencephalography (EEG) is a technique that detects the endogenous electrical activity of the brain by measuring voltage changes between pairs of recording electrodes. This brain activity is primarily generated by neurons located in the gray matter of the cerebral cortex. [0003] EEG is very useful for monitoring brain health in patients with various conditions that result in abnormalities in endogenous brain electrical activity. In addition to its central role in detecting epileptic activity, EEG has also been shown to be useful in other situa...
