Moreover, the degree of this modulation correlated with baseline connectivity strength. These results provide insight into how novel BSEP based network biomarkers can evaluate the modulation of large-scale networks across multiple timescales.

We measured brain stimulation evoked potentials (BSEPs) to evaluate how network dynamics change after a brief trial of DBS during #iEEG. The effects were not immediate, and only after DBS was delivered for >1.5 hours, we observed that BSEP amplitude was reduced compared to baseline.

Thalamic Stimulation Induced Changes in Network Connectivity and Excitability in Epilepsy Objective The effects of deep brain stimulation (DBS) manifest across multiple timescales, spanning seconds to months, and involve direct electrical effects, neuroplasticity, and network reorganizat...

Super excited about this paper where we observe how thalamic stimulation changes network connectivity. Lead by Nick Gregg with Gabriela Ojeda Valencia, Tereza Pridalova, Harvey Huang, Vaclav Kremen, Brian Lundstrom, Jamie V Gompel, Kai Miller, and Greg Worrell

Congratulations!!

Let’s try?

This is an #iEEG study (thanks for suggesting the tag @vanmedge.bsky.social)

Human pulvinar stimulation engages select cortical pathways in epilepsy The pulvinar has been proposed as an effective neuromodulation target for patients with posterior quadrant and temporal epilepsies. However, the pulvinar has a large tissue volume, multiple subnuclei, and widespread cortical connections. It remains unknown whether electrical stimulation of distinct pulvinar subregions affects the temporal, occipital, and parietal areas differently. To address this gap, we delivered single-pulse electrical stimulation to the pulvinar and measured the resulting brain stimulation evoked potentials in twelve patients undergoing stereotactic EEG for drug-resistant epilepsy. Brain stimulation evoked potentials were parameterized across the occipital, temporal and parietal cortex. Stimulation of the lateral pulvinar elicited significant brain stimulation evoked potentials in striate and extrastriate areas that diminish as stimulation shifts towards the medial pulvinar. Conversely, stimulation of the ventral aspect of the medial pulvinar produced significant lateral temporal evoked potentials, which diminish with lateral pulvinar stimulation. We also found that stimulation of the dorsomedial pulvinar evoked significant parietal responses with limited striate/extrastriate and lateral temporal responses. These results demonstrate that electrical stimulation of specific pulvinar subregions influences distinct occipital, parietal and lateral temporal areas. Selective targeting of pulvinar subregions to maximize seizure network engagement may be essential for individualized treatment of posterior quadrant and temporal epilepsies. ### Competing Interest Statement N.M.G is an industry consultant for NeuroOne.
