It's a Happy #FluorescenceFriday when we get a personal tour of the Western Lightsheet Microscopy Core, part of @touchscreencog.bsky.social + an integral part of #TRIDENT! 🧠 🔬 Sound intriguing? See more below🤓! @mind-western.bsky.social @lifecanvastech.bsky.social #NFRF youtube.com/shorts/AA91I...

The TRIDENT proof-of-concept platform began in 2023 through the incredible support of a $24M grant from the Government of Canada's New Frontiers In Research Fund- Transformation stream. Check out our website tridentpreclinicaltrials.org or the video below 👇 #NFRF www.youtube.com/watch?v=RCr3...

Going for a rollercoaster ride on the spinal cord! 🤩

Great to be in Toronto for the Second AG meeting for @tridentpct.bsky.social where our 🐁 molecular and cognition core will show what we are up to in the last 2 years facilitated by @touchscreencog.bsky.social and we will continue to learn about our organoid and marmoset models.

Had a great time at the @mind-western.bsky.social Lightsheet Meeting Series this week, an amazing, interactive talk led by Christopher Pfeiffer-Kelly of LifeCanvas Technologies Inc. @braincanada.bsky.social @maximoprado.bsky.social🔬🖥️🤩

Follow an exciting new brain imaging platform, @mind-western.bsky.social, partnering group of #TRIDENT. Article about it linked below! 👇🔬👀 www.schulich.uwo.ca/about/news-e...

Great collaborative effort to get this done

How does the brain work? Scientists are closer to the answer with the largest wiring diagram and functional map of a mammalian brain to date. 🧵 🧠📈

It is #fluorescencefriday and the MIND platform @touchscreencog.bsky.social @tridentpct.bsky.social invites you to see brain blood vessels stained with CD31 and imaged by lightsheet. 🐁 🧠 cleared with SHIELD . thanks as always to @shahrzadbahrampour.bsky.social @arashsalah.bsky.social and company.

Hey #AAIC25 check out Arash’s presentation today at 8 AM and see some cool whole brain videos of the vasculaturs and plaques plus touchscreen testing room 106 Evaluating the Efficacy and Risks of Early Lecanemab Treatment in APOE4 Humanized Alzheimer’s Disease Mouse Models also poster 151
