Our latest! We demonstrate contributions of the Vis, Dorsal Attn, and DM networks to long tau spread in PCA - with a "saturation-invasion" model that captures a dynamic shift in epicenters across these nets. www.nature.com/articles/s44... w/ @relajoie.bsky.social and various Bluesky-less collabs😊

We’re offering free vaccine clinics in Boston. Vaccines are safe, effective, and protect against serious illness. Getting vaccinated keeps you healthy and helps protect your family, friends, and community. Learn more at boston.gov/vaccine-clinics.

A group of young people sit on a bench behind a fence at a baseball diamond. Text reads, “FREE Vaccine Clinics in Boston. Get your flu and COVID-19 vaccines for free. No appointment necessary, walk-ins welcome. Find dates, times, and locations at boston.gov/vaccine-clinics.” The logos for the City of Boston, Boston Public Health Commission, Boston Public Schools, Boston Centers for Youth and Families, Legacy Care Group, and Shaw’s Star Market are at the bottom.

The plan for NIH is in, source with full 64 page proposal for all of HHS is linked. Reported in WaPo. This is catastrophic. Reduction to 8 centers. 40% cut in budget. 15% IDC cap. This will decimate science across America open.substack.com/pub/insideme...

🧵Yesterday, I received notice that my #NIH grant, on the social environment, lifecourse, epigenetics & #birthoutcomes in Black families, was terminated. This grant represented a critical effort to address the ⬆️ rates of maternal & infant mortality in the US, particularly among Black mothers & babies

**New Preprint** We show that pooling morphometric estimates via "cluster scanning" (i.e., repeat T1w MPRAGE scans with AT = ~2 min/ea.) allows detection of cortical atrophy in phenotypically vulnerable regions in phenotypes of AD and FTLD over 3- and 6-months. www.medrxiv.org/content/10.1...

***New preprint!*** We show that 18F-Flortaucipir PET signal within the canonical DMN is a relatively specific and strong predictor of clinical decline in early symptomatic patients with atypical AD clinical syndromes.
