    Seems like we have more days in the red though, non?

    Congratulations to Dr. John Rolston, , and the entire epilepsy team ! 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. – mjesto: Clinical Neurosciences Center - UUHC

    So my uncle Wangchuk is a traditional Tibetan artist and he made this Tibetan thangka version of the cat meme.

    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. Information limiting correlations 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). Check out the paper for full gif explanations... !

    New showing the effects of epileptic seizures on individual human neurons, and what this means for our understanding of where seizures are actually happening:

    Very interesting! Microelectrode recordings are critical for such a fine scale analysis.

    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 '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.

    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.

    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.

    First, early discharges are more broadly spatially distributed on ECoG, even more widespread than the later discharges that are associated with intense action potential firing, and phase-locked high frequency LFP that indicates seizing brain tissue.

    In this preprint, we used microeletrode array and ECoG recordings of human seizures to contextualize the clinically used LFP with action potential recordings. Can we see differences that would imply early inhibitory discharges?
