“…Comparisons between ERC with and without SPES during particular sleep stages may be considered in future analyses but are beyond the scope of this report. Lastly, to reduce the risk of our baseline being affected by preceding SPESs at 1-second intervals, we excluded sites within the seizure onset zone, in which stronger and more prolonged inhibition of HG can sometimes be elicited by SPES [16]. We also excluded sites with frequent epileptiform discharges.…”

“…CCSRs, a term firstly introduced by Gkogkidis et al [11], occur at a variety of frequencies, including high-gamma (HG) bands. For example, Maliia et al recently investigated HG responses to SPES in human physiologic and pathological networks [16]. HG activity is also widely used as an index of changes in neuronal population firing rates [17][18][19].…”

Wakefulness and sleep arise from global changes in brain physiology that may also govern the flow of neural activity between cortical regions responsible for perceptual processing versus planning and action. To test whether and how the sleep/wake cycle affects the overall propagation of neural activity in large-scale brain networks, we applied single-pulse electrical stimulation (SPES) in patients implanted with intracranial EEG electrodes for epilepsy surgery. SPES elicited corticocortical spectral responses at high-gamma frequencies (CCSR HG , 80-150 Hz), which indexes changes in neuronal population firing rates. Using event-related causality (ERC) analysis, we found that the overall patterns of neural propagation among sites with CCSR HG were different during wakefulness and different sleep stages. For example, stimulation of frontal lobe elicited greater propagation toward parietal lobe during slow-wave sleep than during wakefulness. During REM sleep, we observed a decrease in propagation within frontal lobe, and an increase in propagation within parietal lobe, elicited by frontal and parietal stimulation, respectively. These biases in the directionality of large-scale cortical network dynamics during REM sleep could potentially account for some of the unique experiential aspects of this sleep stage. Together these findings suggest that the regulation of conscious awareness and sleep is associated with differences in the balance of neural propagation across large-scale frontal-parietal networks.

“…Other investigations into optimal stimulation paradigms and excitation properties of certain cortical or subcortical areas could benefit our understanding of both normal regional physiology and pathologic excitability (45)(46)(47)(48). Such investigations could include high-/low-frequency stimulation paradigms or rely on SPES (49)(50)(51)(52). Improvements in SEEG lead construction could be undertaken to improve the stimulation efficacy and recording capabilities, such as with hybrid electrodes (53,54).…”

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.

“…In this issue of Clinical Neurophysiology, Mălîia et al (2017) have further explored the spectral changes at gamma, ripples and fast ripples provoked by SPES at different time windows and at different brain regions. With this new methodological approach, they have categorized three different periods after SPES (10-60, 60-255, 255-500 ms), compared to baseline pre-stimulation periods.…”
