I’m an engineer, neurologist, and neuroscientist interested in causal mapping of neurological and psychiatric symptoms to human brain circuits to identify therapeutic targets for neuromodulation. #DBS, #TMS

Could the Parkinson’s drug levodopa prime the brain to respond better to intensive rehabilitation following a stroke or injury? Enter the idea: Let’s give dopamine pills after a stroke? Spoiler alert: This new large, randomized trial published in JAMA revealed no added benefit in recovery.

Boom: The results of the ADAPT-PD personalized brain stimulation trial showed promise for treating Parkinson’s. First longer-term results for adaptive DBS in PD. Adaptive stimulation automatically adjusts in real time to a person’s brain signals. @parkinsondotorg.bsky.social

What is the update for skin biopsies to differentiate Parkinson's vs. MSA? Spoiler alert: under confocal microscope, skin biopsies look different in PD vs MSA. Donadio and colleagues describe in a new paper in Brain the uses of intraneural phosphorylated α-synuclein. @parkinsondotorg.bsky.social

Can connectomic DBS go beyond where to stimulate to inform who and when? Great discussion @dbsthinktank.bsky.social with @rolstonjohn.bsky.social @julianneumann.bsky.social suggest yes! @braincircuits.bsky.social

In #DeepBrainStimulation

the two major developments across the last decade have been

1. Adaptive DBS and
2. Connectomic DBS

In a @natrevneurol.nature.com article with @julianneumann.bsky.social, we ask:

Could the two be united into a common framework?

House subcommittee version just came out (link below). Holds NIH flat at $48 billion.

To be clear: this is far from over. But a good sign that science still matters across both sides of aisle.

Remarkable. Uncontrollable laughing or crying can happen *without* emotion ("pseudobulbar affect"). Here's a video of one individual whose crying is triggered by real or imagined rubbing of his finger & thumb. Intense response but not sadness. /1

Our latest study links polygenic risk for TLE-HS to cortical thinning in kids—mirroring patterns in adult patients.

Early imaging-genetics insights could reveal interplay of epilepsy risk and phenotypes before symptoms emerge.

Can specialized physical therapy help you to live longer with Parkinson’s? What if physical therapy did more than improve balance and reduce falls? Specialized physical therapy, like that provided through the PDNet model linked to a modest but real reduction in mortality for people w/ Parkinson’s.

Is there a brain circuit target for restoring consciousness after brain injury? New work by @rolstonjohn.bsky.social @braincircuits.bsky.social says yes!
Just dropped in @natcomms.nature.com: we show that re-engaging a thalamic–ventral tegmental circuit with deep brain stimulation can reignite consciousness in patients with severe brain injury. Work led by Aaron Warren, with @andreashorn.org @foxmdphd.bsky.social @ others! tinyurl.com/4kz8j89b

Can we rewire and recover from an eating disorder? We must understand the actual underlying brain circuits. A terrific review in Nature Reviews Neuroscience urges us all to rethink eating disorders, not just as psychological struggles, but rather as disorders of brain circuitry. #bingeeating
