PNAS method for dynamic phase-coherence networks prioritizes timing over amplitude coupling across distant regions—computational neuroimaging tool relevant to large-scale neural coordination analyses ().

  • A PNAS Neuroscience paper introduces a method for uncovering dynamic human brain phase-coherence networks.
  • The work appears in Proceedings of the National Academy of Sciences, Volume 123, Issue 35 (September 2026).
  • It targets how the human brain coordinates activity across distant regions—central to explaining cognition and behavior.
  • Most existing approaches study these long-range interactions by tracking changes in signal strength (amplitude).
  • The new approach instead emphasizes phase coherence—timing relationships—over amplitude coupling between distant regions.
  • The method is framed as a computational neuroimaging tool for analyzing large-scale neural coordination.

Multiphoton population imaging in zebrafish piriform homolog decomposes mixed-selectivity modes for odor identity and temporal context—clean neural-dynamics/population-coding methods adjacent to decoding practice. Preprint translational path is indirect.

  • Adult zebrafish telencephalic area pDp—the homolog of piriform cortex—was studied for experience-dependent representational learning of odors and temporal context.
  • Researchers measured neural activity with multiphoton imaging through a prism in head-fixed fish performing an odor discrimination task.
  • Population dynamics in pDp decomposed into independent modes of distributed activity across mixed-selectivity neurons.
  • Those modes jointly encoded odor identity and temporal context rather than separating the two into exclusive cell classes.
  • The work frames piriform-like cortex as building joint, experience-dependent population codes for what was smelled and when.

JNE MEG resting-state alpha/beta connectivity compares ASD, SPD, and controls with behavioral links—electrophysiological biomarkers of sensory dysfunction, adjacent to non-invasive BCI sensing ().

  • A Journal of Neural Engineering MEG study measured resting-state alpha and beta band functional connectivity in male children with autism spectrum disorder (ASD), sensory processing dysfunction (SPD), and typically developing controls (TDC).
  • Sensory processing dysfunction affects most people with ASD and also at least 5% of children who do not have ASD.
  • Links between sensory dysfunction and resting-state brain activity are still incompletely mapped.
  • The study tested group differences among ASD, SPD, and TDC cohorts in resting-state alpha and beta oscillatory activity.
  • It also examined how those alpha and beta resting-state measures relate to behavioral scores of sensory function.

  • Findings focus on early disease, when population-level neural organization begins to break down alongside behavioral change.
  • The model is virus-induced and longitudinal, allowing repeated measures of neural population dynamics as pathology develops.
