New preprint led by @thelablab:
Our meta-analysis of 579 neuroimaging studies finds little evidence for a single, fixed neural core of consciousness. Instead, the findings support distributed systems that combine differently depending on context.

See paper by @misicbata et al.
This indirectly relates to our current understanding of pain. Network-level integration is necessary for proper pain processing. An anesthetized organism does not respond to noxious input.

Nadinda et al. identify variations in the network structure of cognitive-affective-behavioral factors in individuals with chronic low back pain, indicating the need for a more personalized approach. Learn more in #PAIN bit.ly/4qb8Xr6

@netphys1 et al. find that patients with chronic pain and high post-traumatic stress symptom show decreased working memory brain activity and have stronger connections to threat-related brain regions under high cognitive load. Learn more in #PAIN bit.ly/4wFTSjp

The code for our paper has been released: github.com/ThomasYeoLab/CBIG…!
We showed that MS-HBM can reliably estimate individual-specific rs-fMRI networks in drug-resistant epilepsy and that individual-specific language network topography can predict task-fMRI language dominance.

In a formal comparison of heat-evoked skin conductance analysis approaches, @laurenatlas et al. find that combining automated scoring with manual artifact detection reveals strongest associations with pain. Learn more in #PAIN bit.ly/3TYPqhl

Original: Vincenot, Potvin et al. (@UMontreal) showed that individual pain modulation trajectories provide richer insights than traditional mean-based analyses
—it may predict chronic pain risk and improve personalized pain care

Dealing with difficult people may be hazardous to your health.
Data: Each additional "hassler" in your network predicts 1.5% faster biological aging—and worse health a year later. Non-spouse family hasslers are the most problematic.
Some ties aren't worth the toll they take.

Most neurons seem to be generalists, not specialists. Cortical circuits prioritize diversity over categorical structure.
Rarely categorical, highly separable representations along the cortical hierarchy

PatientSpace: A multimodal graph-based latent representation framework for modeling neurodegenerative disease heterogeneity
• A multimodal Variationnal autoencoder learns the latent space with consistency loss.
• Graph-based neighbors yield interpretable matches in diagnosis and imaging features.
• MCI projection into PatientSpace supports early identification of converters.

Original: Drs. Magel, Davis, & Buchman, et al. investigated whether framing chronic pain as a brain disease reduces the stigma that adults without chronic pain place on a fictional person with chronic pain.

The paper argues that two major puzzles (how the brain creates a unified experience and maintains an “edge-of-chaos” state) may be explained by continuous electromagnetic fields generated by neural activity.
