Accuracy and Workflow Improvements for Responsive Neurostimulation Hippocampal Depth Electrode Placement Using Robotic Stereotaxy

Frontiers in Neurology, 2020
Background: Robotic stereotaxy is increasingly common in epilepsy surgery for the implantation of stereo-electroencephalography (sEEG) electrodes for intracranial seizure monitoring. The use of robots is also gaining popularity for permanent stereotactic

Implantation and reimplantation of intracranial EEG electrodes in patients considering epilepsy surgery

Epilepsia Open, 2023
In patients with drug‐resistant epilepsy who are considering surgery, intracranial EEG (iEEG) helps delineate the putative epileptogenic zone. In a minority of patients, iEEG fails to identify seizure onsets.

Implanted Electrodes and Microneedle Array Electrodes for the Neuromodulation

Highlights in Science, Engineering and Technology, 2022
In the human body, nerve conduction plays an important role. A range of physiological reactions and movements in the human body require nerves for transmission. Nerves realize the function of conduction by transmitting bio-electrical signals. If the nerves are damaged, the biological signals will not be transmitted, so the human body's reactions cannot
