Subdural grid electrode (SDE) were the predominant method for invasive EEG from the 1980s into the early years of this century. Though SEEG has largely supplanted SDE, the latter remains a useful technique for patients in whom SEEG may not be appropriate or prove inadequate to map the seizure focus.

In this article, the authors describe the techniques for intraoperative placement of grid and strip electrodes for extraoperative study of a seizure focus. Methods to enhance the efficacy of this technique while minimizing complications are reviewed.

NeuroNexus offers ultra-flexible EEG and ECoG arrays specifically designed to be placed on the surface of the mouse or rat skull or the brain. These surface grids provide high recording resolution and are meticulously designed to conform closely to the brain surface, ensuring optimal electrocorticography measurements.

2022年5月1日 · Epidural grid monitoring (EDG) without opening the dura is thought to reduce the possibility of these complications. We report our experience with EDG. We described our surgical technique of EDG in invasive intracranial electroencephalography (iEEG) monitoring.

Resective brain surgery is the gold standard for treating drug-resistant focal epilepsy. When a surgical plan cannot be developed via non-invasive tests, intracranial EEG (iEEG) recordings are obtained for epilepsy localization. Subdural EEG (SDE) and stereotactic EEG (SEEG) are the two major iEEG tools used in practice.

2022年1月1日 · Electroencephalography (EEG) and electrocorticography (ECoG) are two important neurophysiologic techniques used in the operating room for monitoring and mapping electrical brain activity.

In the NHP, the identification of standardized EEG electrode positions is more complicated and time-consuming. Here we introduce a surface metric and software package (NHP1020) that automates the planning of large, approximately evenly …

2018年1月23日 · Electrocorticography (ECoG) is an electrophysiological technique that records brain activity directly from the cortical surface with high temporal (ms) and spatial (mm) resolution. Its major limitations are in the high invasiveness and in the restricted field-of-view of the electrode grid, which partially covers the cortex.

EEG provides a noninvasive physiological examination of the brain that allows characterization of neuronal discharge patterns.

Depth EEG is the surgical placement of intraparenchymal electrode contacts that are along a thin, flexible, plastic tube. Grid and strip electrode contacts exist within a plastic sheet that is laid across the cerebral convexity and are discussed in Chapters 32 and 33 .
