We used quantitative EEG analysis to assess changes in sleep macro and micro-architecture. We found tau pathology disrupts NREM and REM sleep, specific to the light period, but compromising beta activity which normally reflects cortical synchrony and GABA activity.

EEG recordings confirmed this state of hyperexcitability and lack of coordination among brain networks, while wide field optical imaging showed exaggerated responses of excitatory neurons to sensory stimulation, despite less glutamatergic neurons, confirming hyperexcitability in the system.

By tracing how glucose is used in the brain, we discovered that tau redirects glucose toward making glutamate and not ATP. This increased excitatory activity, reduced inhibition. This creates E/I imbalance that favors overexcitation, even though brain's mitochondria remains intact.

In this study, we show that tau pathology rewires how the brain uses energy, causes hyperexcitability, network desynchrony, and sleep loss. In mice, we found that tau surprisingly preserves normal body-wide metabolism and daily fluctuations in metabolic rhythms typically lost with aging.

I forgot about this!

#ArtAdventCalendar Day 7

Watercolor, mouse, EVs.

Painted it for my student after we discovered a method to isolate EVs from the interstitial fluid of the mouse’s brain (Pait et al, 2023).

At SFN? Check out Dr. Karina Meyer-Acosta’s talk on APOE, neurodevelopment, and network formation using organoids. We were lucky to have Kaisha join the lab earlier this fall from Dr. Jenny Hsieh’s lab for her postdoc!

At #SFN2025? Stop by @ncons95.bsky.social and Sierra’s posters to learn about research from the lab!

Confocal bat signal! Or Ant-man maybe? Guess that makes Clair our lab’s super hero!!!

Absolutely fantastic talk and visit with @mzilberter.bsky.social ! Thanks so much for coming to visit us in Kentucky and sharing your elegant work, Misha!

I’m absolutely elated to hear our UK Prep R25 received its NOA for this year! So glad our lab’s very own, Sierra Turner, can continue on in this program!!!

What a day for the lab!

Clair Ashley CRUSHED her quals and is officially a PhD candidate!

Amunet Jacobs, MD/PhD student, got her white coat and is officially part of the lab!

Nick Constantino got not one but two awards!!

1) Poster award at CASH-KY Symposium & 2) SFN Trainee Development Award!

My attempts to paint more- small watercolors of 1) Owl seen in Whistler at recent Keystone conference & 2) Gull (or sandpiper maybe?) from trip to CT to visit family.

Diggin my painted memories...

I seem to be in a bird phase…

Needed to escape into art. Watercolor doodle of a Carolina Chickadee/Black Capped Chickadee. Couldn’t really tell which was dining at our bird feeders.

Relieved, grateful, and most of excited to continue exploring how metabolic reprogramming contributes to Alzheimer’s disease progression.

Thankful for our CART grant and recent NOA from the NIA to support this work.
