Eye opening!
@cognijunior.bsky.social we have a brain health & sleep program, let's get to work on a stress reduction program ...
#OHBM2026 such an inspiring keynote by Dr Maiden Nedergaard talking about the glymphatic system. My work is heading there next with @muriahwheelock.bsky.social @briangordon81.bsky.social and I am all pumped up 🦸so here is my take away

Fascinating thread by @gordonneuro.bsky.social on a new discovery of functional chain architecture in prefrontal cortex. Evidence presented is very compelling. My take:
New paper in Imaging Neuroscience by Andrew N. Van, Nico U.F. Dosenbach, et al:
Frame-wise multi-echo distortion correction for superior functional MRI
doi.org/10.1162/IMAG...
Thalamic recordings show a rhythm that’s strong in wake and REM and absent in deep sleep: An electrophysiological signature of conscious states.

Proud of this team for this multidimensional tour de force! By decoding EEG signal, we show that the brain handles competing distractors through rapid dimension-specific modulation based on a multivariate conflict signal. More in @davideghez.bsky.social's 🧵. Paper: doi.org/10.1101/2025.11.16.688701
New preprint!
Last year we showed humans adapt attention in a dimension-specific way when multiple things compete for attention. Now we read out the neural dynamics of this adaptation. doi.org/10.1101/2025.11.16.688701 w/ @mikefreund.bsky.social @theazalabak.bsky.social @wouterkool.bsky.social
This is going to be my conversation starter at #ohbm2026 @ohbmofficial.bsky.social
Starting puberty changes the brain and that start timing matters. At 9-11 years old, girls are already experiencing these changes strongly.
So excited to present this work at #ohbm2026 ➡️ Tuesday afternoon at the neural circuits of memory and learning oral session chaired by @rosannaolsen.bsky.social & Carl Hodgetts
➡️ Wednesday and Thursday at the poster 3103
Chowdhury et al. report the discovery of a 19–45-Hz thalamic oscillation that is present during human wakefulness and REM sleep, but not NREM sleep.

The 6x US memory champion – Nelson Dellis – can memorize a deck of cards in 40 seconds and knows the first 10K digits of pi.
To figure out how, he let us peak inside his brain. Here is what we learned in our precision brain mapping study www.biorxiv.org/content/10.6...

In sum, SES dominates childhood brain organization. Zip code matters most.
These findings have been at the forefront of my mind daily, with Darwin’s quote living rent free in my head: “if the misery of the poor not be caused by the laws of nature, but by our institutions, great be our sin.”
Navigating competing attentional demands is a core cognitive function, yet how the brain tunes control in multidimensional environments remains poorly understood. Here, we used a multidimensional task-set interference paradigm in which participants attended to one of four stimulus dimensions while three others acted as distractors, combining multivariate decoding, representational similarity analysis, and encoding models applied to human EEG. Targets and distractors were initially encoded in parallel, but distractor representations were rapidly suppressed ~250 ms after stimulus onset, with suppression scaling with each distractor's own conflict history. Neither trial-to-trial adaptation nor block-level learning produced anticipatory changes in task-relevant representations. Instead, proactive control modulated the speed and efficiency of stimulus-triggered suppression. Encoding models further revealed that conflict is represented in orthogonal, dimension-specific subspaces that eventually collapse onto a shared conflict signal. These results show that multidimensional attentional control operates through selective, reactive suppression of distractor representations, guided by a structured multivariate conflict signal. ### Competing Interest Statement The authors have declared no competing interest.

I always assumed that brain function had to line up with cytoarchitectonics.
It turns out I was wrong.
Human cortex, especially PFC, is tiled by chains of functional patches that subdivide and interlink architectonic areas into parallel processing streams.

Excited to share our new preprint “Functional brain network correlates of pubertal timing and depressive symptoms in preadolescence” doi.org/10.64898/2026.05.22.727009
We examined how pubertal timing relates to whole-brain functional connectivity and depression risk in >9,000 youth (ABCD Study)
