“…Similarly, anaesthetic outcomes of SEEG have not been systematically reported in prior series. 22 In this series, only two anaesthetic complications occurred, which is lower than anaesthetic complication rates associated with epilepsy surgery procedures. 23 Neuroanaesthesia for SEEG implantation has several unique aspects, most notably avoidance of long-acting sedatives and benzodiazepines, to minimise EEG and seizure suppression.…”

BackgroundSurgical management of refractory focal epilepsy requires preoperative localisation of the epileptogenic zone (EZ). To augment noninvasive studies, stereoelectroencephalography (SEEG) is being increasingly adopted as a form of intracranial monitoring.AimsThis study aimed to determine the rate of complications for patients undergoing SEEG and to report the success of SEEG with regard to EZ detection and seizure outcome following definitive surgery.MethodsA retrospective cohort design investigated all cases of SEEG at our institution. Surgical, anaesthetic and medical complications with subsequent epilepsy surgery and seizure outcome data were extracted from medical records. Multivariate logistic regression was used to investigate the relationship between both the number of electrodes per patient and the duration of SEEG recording with the rate of complications.ResultsSixty‐four patients with 66 implantations were included. Headache was the most common complication (n = 54, 82%). There were no major surgical or medical complications. Two anaesthetic complications occurred. EZ localisation was successful in 63 cases (95%). Curative intent surgery was performed in 39 patients (59%) and 23 patients achieved an Engel class I outcome (59% of those undergoing surgery). The number of electrodes and duration of recording were not associated with complications.ConclusionsNo patients in our series experienced major surgical or medical complications and we have highlighted the challenges associated with neuroanaesthesia in SEEG. Our complication rates and seizure outcomes are equivalent to published literature indicating that this technique can be successfully established in newer centres using careful case selection. Standardised reporting of SEEG complications should be adopted.

“…The use of sEEG in neurophysiological studies offers an opportunity to record the activity in deeply located epileptogenic areas such as the hippocampus, and amygdala (Tamimi et al, 2022). The implantation surgery is relatively simple, and in some cases, only local anesthesia is used (Grant et al, 2015;Rajkalyan et al, 2019). In the ECoG method, electrical activity is sampled from the cortical surface with the electrodes shaped as strips or grids (Zijlmans et al, 2019).…”

While it is known that the same brain area could be involved in multiple functions, such multimodality has yet to be utilized in applications like brain-computer interfaces (BCI). For instance, could the same BCI decode both hand movements and speech? Here we studied stereo EEG (sEEG) patterns in two patients with epilepsy performing motor and language tasks as parts of the same experimental session. sEEG electrodes were implanted in various regions of frontal and temporal cortices. In the motor task, the patients wrote digits by hand whereas in the language task they pronounced or imagined pronouncing words. The superior frontal gyrus (SFG) and superior temporal gyrus (STG) were engaged in both tasks whereas the middle frontal gyrus (MFG) and middle temporal gyrus (MTG) were engaged only in the handwriting task. In addition to task-execution neural patterns, preparatory activity was observed, particularly the STG. Based on the differences in the STG and SFG, the articulatory versus imagined speech could be decoded using a machine learning classifier. We suggest that multimodal BCIs be used in the future to improve speech restoration and rehabilitation in neurological patients.
