A few days ago, a friend oversaw me reading an imaging paper and asked: “I’ve always wondered how an fMRI works. Do you think I’d be able to understand even if I didn’t know much physics?”. Well, I decided to make a YouTube video answering that: youtube.com/watch?v=Hipq5S…

Decoding Brain Function: The Neuroscience of fMRI
The match is over. Garry Kasparov has won. He beat his old rival Vishy Anand with a score of 13-11. He walks down to the waiting area where he is surrounded by his friends - Rex Sinquefield, Michael Khodarkovsky, Joy Brey. But Garry is in a poignant mood. He is not celebrating.…
bioRxiv has a dedicated section for negative results. Use it. Share negative results. Your colleagues will appreciate it.
ONE OF THE MOST CREATIVE PEOPLE in the history of brain mapping was Keith Worsley (1951-2009), seen in this video solving a cool puzzle in an ingenious way: 🔥 if you have a t statistic at every point on a 3D surface (like the cortex of the brain), how do we know if an…

Mental health can be viewed as energy landscapes. OCD has deep valleys where neural activity gets stuck. Schizophrenia has shallow valleys where neural activity runs freely. This is the dynamical systems theory.

What infant fMRI is revealing about the developing mind
Cognitive neuroscientists have finally clocked how to perform task-based fMRI experiments in awake babies. Now they want watch cognition take shape.
Real and imagined images are processed using the same systems in the brain, yet most people can distinguish between the two. Now neuroscientists have identified two brain regions that keep imagined images separate from reality. go.nature.com/45kzPwj
Our newest manuscript now in Scientific Reports. Title says it all "The relationship of white matter tract orientation to vascular geometry in the human brain" - where does WM align (and not align) with vasculature? @MASI_Lab @vuiis nature.com/articles/s4159…
The vast majority over discoveries are low hanging fruit when they are made. The key to scientific progress is progressively making more fruit low-hanging. One of the deep problems we have in science is that we reward the people who pick the fruit rather than the ones who lower…
A basic question whose answer seems to me to dictate what the near-term future of scientific discovery looks like: is there a lot of attention-bottlenecked low-hanging fruit, or have humans done a reasonably good job finding the easy stuff?

(1/3) New work from our lab and @MASI_Lab creating White matter brain charts across the lifespan. Brain charts for 72 pathways, both microstructure (DTI) and macrostructure (volumes, lengths) - using data from >40 harmonized population studies biorxiv.org/content/10.110…
Can confirm - works great on human AND animal models where b-vectors may have unique or proprietary formats.
