@PeterSjostedtH @theodorus5 @AhQFish No one knows enough about the brain to dismiss any signal as epiphenominal. When someone says "epiphenominal", I hear "doesn't fit my theory". If a theory can't explain data, the theory is the problem, not the data.

New research using AI and MRI on the lower leg points to a simple takeaway: bigger calf muscles can push down harder at the ankle—think a stronger push when pointing your toes or pushing off when you walk. Extra fat inside the muscle doesn’t.

🧠 Why have EEG/MEG alpha phase studies been so inconsistent about effects on #perception?
NEW PREPRINT: Individual differences are key. Our new Neurobehavioral Link Function proves alpha phase CAUSALLY shapes #multisensory integration.

Thread on a new paper by Ned Block (@De_dicto): "Can only meat machines be conscious?"
Main point: many discussions assume that only the computational & functional features of a system are relevant to whether it's conscious. But the underlying biology might also matter. 🧵1/

In a sense yes, but does network science help us understand the brain as a complex system?
Intriguing paper.
If anything the paper has 800+ refs!

@nico_hinrichs @PessoaBrain Will read. But the real question is: do our imaging tools and analyses actually capture brain complexity and dynamics? Let’s first grasp what amplitude, temporal dynamics, and connectivity mean perceptually. Then decide if it’s really a “complex network".
English
@PessoaBrain I certainly hope it does! Geometry might then help us understand it better ;-)

Original: Williams, Dr. @Pain_NeuRa &al. examined the reliability and measurement error of two commonly used pain scales in people with low back pain.
—small changes in pain intensity scores should be interpreted cautiously

Excited to share the first in our series of papers using hypothesis-driven analyses to identify reproducible, verifiable biomarkers of chronic pain. We compared ML vs. statistical accuracy and validated findings across three cohorts (N=197, one offsite).

@netphys1 et al. find that chronic low back pain is associated with hyperconnectivity between the nucleus accumbens and prefrontal cortex regions, a pattern that predicts pain intensity and was partly reproduced between different study cohorts #PAIN bit.ly/4neD5zr

We are having an amazing time learning about the brain circuitry at the Canadian Association for Neuroscience meeting in Toronto. Not a lot of human brain neuroimaging or pain mechanisms, but hey, that can change!
