Last week @halpernc and team performed the first responsive deep brain stimulation (DBS) for obesity in the world! This is the first of 6 planned #DBS surgeries for severe #obesity funded by @NIH and @US_FDA approved. ow.ly/Qchc50ycfZm pic.twitter.com/TkzSgrHBF0

Congratulations to Dr. John Rolston, #neurosurgeon , and the entire epilepsy team @UofUHealth! Last week, they were the first in the world to use a mini-robot to place a closed-loop stimulator in a patient who suffers from epilepsy. #robotics #functionalneurosurgery #Medtronic pic.twitter.com/D4Kxc6UDIa

Our paper supporting a theory first put forth in 1994 by Zohary et al. That suggested that correlations could limit information in large neural populations.

Turns out, action potentials in neurons that are recruited to the seizure become shorter in amplitude, and longer in duration (above), and that this is exclusive to the "core" of the seizure (anterior cingulate here).

Very interesting! Microelectrode recordings are critical for such a fine scale analysis. twitter.com/50kDinar/statu…

These results further emphasize the importance of examining the high frequency LFP spectrum to contextualize seizure recordings in epilepsy research and point to broadband high frequency LFP's utility for understanding seizure mechanisms in the clinical setting.

These analyses were inspired by work from @LMPrida's lab and further confirm that broadening of the high frequency LFP spectrum is associated with increased population neuronal firing under an electrode, even if that electrode may not be able to record action potentials.

Finally, back to that narrowband gamma, we show that action potentials measured on the microelectrode arrays differentially couple to narrowband gamma before and after the neuronal signature of recruitment into a seizure. pic.twitter.com/rgTOwKtloB

We show this spectral broadening associated with seizing brain tissue can be clearly observed in the spectrum, or measured for each discharge in a seizure using information theoretic quantities. pic.twitter.com/EdPmeOmfmT

Note the clear narrowband gamma peak in the above spectrogram, and the increased broadband high frequency LFP after about 40 seconds. The narrowband gamma doesn't distinguish seizing brain tissue, but the broadening of the spectrum in later discharges does. pic.twitter.com/WQ4VjEySdC
