Huzzah for @stevenmeisler.com, whose preprint on our new fully-processed ABCD dMRI data resource is now out. The super-clear results from this monumental effort will undoubtably change the way we approach studies of white matter development going forward.
Diffusion MRI (dMRI) is a powerful tool to study white matter maturation. In our new preprint, we process and distribute a new resource of >24,000 ABCD dMRI scans using open source tools! We then evaluate how methods shape inferences about development.

David Kleinfeld’s Sprague Lecture at @PennMINS deeply thought-provoking. Volitional control of behavior highlights that touch isn’t passive—the brain actively samples the world. Essential thinking for somatosensory neuroscience. #ActiveSensing#Neuroscience#Touch

The MRI Neuroanatomy Post 🗞️
The parieto-occipital fissure (yellow) divides the occipital lobe from the parietal lobe and intersects the calcarine sulcus (pink) - resembling a tilted "Y".
The primary visual cortex lies along the calcarine sulcus.
Above the calcarine sulcus lies the cuneus (green) - the site of basic visual processing.
Below the calcarine sulcus lies the lingual gyrus (blue) - needed for face & landmark perception and recognition, and visual memory.

MRI Neuroanatomy 101 🧠
The red nuclei (red), mammillary bodies (pink), optic tracts (yellow), & cerebral peduncles (dark blue) are marked here.
Fibers of the cerebral peduncle are organized from anteromedial to posterolateral as:
- frontopontine (FP)
- corticobulbar (CB)
- corticospinal (CS)
- temporo-parieto-occipito-pontine (TPP)
Notice the ICA branching into the first segments of the anterior cerebral artery (A1) and middle cerebral artery (M1).
Try to trace these structures on the opposite side!
