(1/8) My latest study is out in @Nature ! Kudos to coauthors especially @jess_cardin and to @KavliAtYale and @WuTsaiYale for support. We find that gamma power in mouse visual cortex is caused by brief events supporting visual processing https://t.co/h45HEg0LpX

Sex at birth may not be purely random, according to a new @ScienceAdvances study.
Instead, each family’s likelihood of having only male or only female children is a “weighted coin toss” influenced by maternal age and genetics. https://t.co/msMvLfLuuz
Neuronal activity influences the growth of #myelin sheaths along axons by signalling through metabotropic glutamate receptor 5 (mGluR5) on oligodendrocytes

Today in @Nature, we report a spatial single-cell atlas of human cortical development, revealing surprisingly early specification of human cortical layers and areas.
We built an interactive browser to explore the spatial data: https://t.co/Xy3JcsSpYw

Thrilled to share our paper, New in @ScienceMagazine! We show that transiently boosting ketamine-induced ERK activity prolongs its antidepressant effects via enhanced synaptic plasticity and synaptogenesis in CA1. Grateful for all the support and guidance from mentors and colleagues @VanderbiltBrain & @VandyPharm along the way! @LisaMonteggia, Ege Kavalali, @natalieguzi, Ji-Woon Kim, etc.
Also, thank Dr. Hashimoto for the nice perspective on our paper.

A new Science study finds that different dendritic segments of a single neuron follow distinct rules. The results challenge the idea that neurons follow a single learning strategy and offer a new perspective on how the brain learns and adapts behavior

Glioblastomas hijack the normal brain circuitry for rapid proliferation. Fascinating @Nature study showed that malignant brain tumors, or gliomas, infiltrate and integrate across brain networks. Pharmacologic blockade of neuron-glioma interaction reduce tumor proliferation.

Wouldn't it be cool to be able to stimulate deep within the brain without the need for brain surgery (i.e. DBS), and without actually making a physical lesion in the brain (i.e. focused ultrasound or pallidotomy)? This paper provides 'proof of concept' that a transcranial ultrasound stimulation (TUS) approach may be achievable. Darmani, Chen and colleagues bring us up to speed in Nature Communications.
Key Points:
- The authors provide an interesting study that examined TUS-induced changes in 10 individuals w/ Parkinson’s and dystonia.
- There were also 15 healthy controls.
- Physiology and local field potentials were sampled from deep brain stimulation leads w/in the globus pallidus.
- Theta burst TUS increased theta power during DBS.
- The authors showed 10 Hz TUS enhanced beta power and the effect persisted for ~40 min.
- Interestingly, the GPi TUS actually prolonged stop-signal reaction times. There was also impaired response inhibition.
My take: What was interesting was that transcranial ultrasound was able to engage a common target (GPi) used for DBS surgery and focused ultrasound. We all remain 'deeply' interested in noninvasive deep brain stimulation as this could open the door for a safer and potentially (one day) a more practical approach for stimulating from 'outside the brain.' The field has a ways to go, but this is a nice early step. It is critically important that the authors were able to show us that TUS was able to 'modulate neural circuits in a spatially precise manner.' We must – respice finem – consider the outcome, when developing the less invasive methods of brain stimulation. I don't think we should be too disappointed with the early results, as this road will be a long but worthwhile journey. https://t.co/WE0F7A2mJT #parkinson #deepbrainstimulation #focusedultrasound @ParkinsonDotOrg@FixelInstitute@Nature@NatureComms@DBSThinkTank
