A Minimally Invasive Endovascular Stent-Electrode Array for Chronic Recordings of Cortical Neural Activity

Abstract

Intracranial electrode arrays for recording and stimulating electrical brain activity have facilitated major advances in the treatment of neurological conditions over the past decade. When compared to scalp electroencephalography (EEG), cortical recordings have demonstrated superior spatial resolution and consequently a greater potential for cognitive command output. Traditional cortical arrays require direct implantation into the brain via open craniotomy, which is a delicate and lengthy procedure. This can lead to inflammatory tissue responses amongst other clinical complications and has necessitated the development of minimally invasive methods that circumvent or mitigate brain trauma. In..
