Four-Channel Optically Pumped Magnetometer for a Magnetoencephalography Sensor Array

Four-Channel Optically Pumped Magnetometer for a Magnetoencephalography Sensor Array

Four-Channel Optically Pumped Magnetometer for MEG Sensor Arrays Background Optically Pumped Magnetometers (OPMs) operating in the Spin-Exchange Relaxation-Free (SERF) regime are highly sensitive magnetic field sensors, with sensitivities as low as 0.16 ft/√Hz and 0.54 ft/√Hz. OPMs are based on the interaction between spin-polarized atoms and magne...

Human Sensorimotor Resting State Beta Events and Aperiodic Activity Show Good Test–Retest Reliability

Human Sensorimotor Resting State β Events and Aperiodic Activity Exhibit Good Test-Retest Reliability Background Neurological diseases are some of the most impactful diseases on daily human life, particularly those affecting sensory and motor functions, such as Parkinson’s disease.

Compared to electro...

Feasibility, Safety, and Performance of Full-Head Subscalp EEG Using Minimally Invasive Electrode Implantation

Feasibility, Safety, and Performance of Full-Scalp Subdural EEG - A Report on Minimally Invasive Electrode Implantation Background and Purpose Since Berger first recorded human scalp electrical signals and discovered the alpha rhythm in 1929, the recording capabilities of electroencephalography (EEG) have significantly improved in terms of spatial ...

Association between Time to Treatment with Endovascular Thrombectomy and Home-Time after Acute Ischemic Stroke

The Relationship between Treatment Speed of Endovascular Thrombectomy (EVT) for Acute Ischemic Stroke and Patient’s “Time at Home” Stroke is an acute disease with high disability and mortality rates. However, in recent years, the treatment efficacy of acute ischemic stroke has improved significantly with the development of endovascular thrombectomy...

Analysis of Cerebral CT Based on Supervised Machine Learning as a Predictor of Outcome After Out-of-Hospital Cardiac Arrest

Brain CT Analysis as a Tool for Outcome Prediction after Out-of-Hospital Cardiac Arrest: A Supervised Machine Learning Analysis Research Background Out-of-Hospital Cardiac Arrest (OHCA) is one of the leading causes of death in the Western world, with extremely low survival rates, ranging from 3% to 16%. The neurological and overall outcomes after O...

Contemporary Cohort of Cerebral Cavernous Malformations: Natural History and Utility of Follow-Up MRI

Natural History and MRI Follow-up of Patients with Cerebral Cavernous Malformations Background Cerebral cavernous malformations (CCMs) are vascular malformations of the brain and spinal cord lined by endothelial cells and lacking smooth muscle. Due to the disruption of endothelial cell permeability and tight junctions, patients may present with foc...
