Congrats!🥳 For people from China/India, there's a wait due to annual country caps. So even if our EB1A was approved, we couldn't get the green card until the "priority date" is current.

Approved sounds like still 18 months wait ahead... speaking from my experience in 2018-2020.

My lab will explore how the human cerebral cortex develops—and what goes wrong in neurodevelopmental disorders—by combining human-based approaches such as brain organoids and spatial omics. 🧬🧠

Huge thanks to our great team. Bioinformatics: Kyle, Shunzhou, and Chunyu from @drmingyaoli.bsky.social lab @pennmedicine.bsky.social ; cell segmentation: @computingnature.bsky.social ; NIHNeuroBioBank; Chris for wonderful mentorship, and other members of Walsh lab.

Seeing is believing- Our study emphasizes the synergistic analysis of molecular and spatial data, yielding insights unattainable through traditional methodologies, and setting the paradigm for a comprehensive spatial developmental atlas of the human brain.

🧠 Also, the six-layer structure of the cortex is detectable by gestational week 22 from excitatory neuron subtypes, despite no visible lamination.

We discovered two distinct modes of cortical areal specification during mid-gestation:
1️⃣ A gradual transition across most cortical regions
2️⃣ A sharp boundary between primary (V1) and secondary (V2) visual cortices, is visible at GW20, long before morphological differences appear.

We are creating a web browser for our MERFISH data with spatial visualization for cell types and gene expression.
Here's the link for a teaser of one sample -human prefrontal cortex at gestational week 20-, with 50+ more to come: webatlas.cog.sanger.ac.uk/dev/index.ht...
