“…Neural data from depth and surface grid electrodes are comparable given the identical contact material, similar surface area, and identical recording hardware. The relative proportion of depth probe and grid electrode implants reflects the major improvements in patient safety and outcome afforded by recent advances in stereotactic electroencephalography 69 .…”

Spoken language, both perception and production, is thought to be facilitated by an ensemble of predictive mechanisms. We obtain intracranial recordings in 37 patients using depth probes implanted along the anteroposterior extent of the supratemporal plane during rhythm listening, speech perception, and speech production. These reveal two predictive mechanisms in early auditory cortex with distinct anatomical and functional characteristics. The first, localized to bilateral Heschl’s gyri and indexed by low-frequency phase, predicts the timing of acoustic events. The second, localized to planum temporale only in language-dominant cortex and indexed by high-gamma power, shows a transient response to acoustic stimuli that is uniquely suppressed during speech production. Chronometric stimulation of Heschl’s gyrus selectively disrupts speech perception, while stimulation of planum temporale selectively disrupts speech production. This work illuminates the fundamental acoustic infrastructure—both architecture and function—for spoken language, grounding cognitive models of speech perception and production in human neurobiology.

“…Assuming these safety considerations are met, the complication rates from SEEG have been shown to be generally low: Mullin et al reported a pooled complication prevalence of 1.3% (hemorrhage, 1%; infection, 0.8%; electrode malpositioning, 0.6%; hardware malfunction, 0.4%; and death, 0.3%) (14), and Cardinale et al reported an overall complication prevalence of 1.8% [three major complications (0.4%) and one fatality (0.1%)] (9). Additionally, SEEG has been shown to have lower morbidity and higher tolerability by patients than subdural electrodes or intraoperative ECoG (13,15). Beyond the safety considerations, additional factors related to the electrical stimulation of neural tissue must be addressed, namely, charge density and charge per phase (1).…”

Stimulation Mapping Using Stereoelectroencephalography: Current and Future Directions

et al. 2020

View full text Add to dashboard Cite

Electrical stimulation mapping (ESM) using stereoelectroencephalography (SEEG) is an essential component in the workup of surgical epilepsy. Since the initial application of ESM in the mid-1960s, it remains unparalleled in defining eloquent brain areas and delimiting seizure foci for the purposes of surgical planning. Here, we briefly review the current state of SEEG stimulation, with a focus on the techniques used for identifying the epileptogenic zone and eloquent cortex. We also summarize clinical data on the efficacy of SEEG stimulation in surgical outcomes and functional mapping. Finally, we briefly highlight future applications of SEEG ESM, including novel functional mapping approaches, identifying rare seizure semiologies, neurophysiologic investigations for understanding cognitive function, and its role in SEEG-guided radiofrequency thermal coagulation.

“…Patient-level variables included patient age, sex, invasive monitoring technique, resection status and location, and pathology, and were selected based on current literature describing their association with patient outcomes. 8 Nation-level covariates were divided into five categories: (1) health & health care, (2) economy & growth, (3) education, (4) environment & poverty, and (5) science & technology. The covariate of neurosurgeon density per 100 000 population was included in the category of health and health care and was analyzed separately from the covariate of physician density per 100 000 population.…”
