A fundamental challenge for animals and humans is resolving competing survival demands under naturalistic threat, yet circuit-level mechanisms remain poorly understood. We developed a paradigm recapitulating a predator-prey encounter: Long-Evans rats emerged from a nest to forage in an open arena, choosing between…

The brain builds meaning from speech in stages, transforming acoustic input into linguistic comprehension. Yet where comprehension separates from general acoustic processing has been difficult to localize, because the two are tightly entangled in continuous speech. Here we align the activity of 145,000 individual…

Behavior arises from the interplay between spontaneous brain dynamics and sensory-driven responses, yet how spontaneous neural activity shapes variability in decision-making remains unclear. We leverage the tractable C. elegans nervous system to address this question. During oxygen avoidance, we observe binary…

Postoperative delirium (POD) is a common complication in older surgical patients and substantially worsens clinical outcomes, yet existing intraoperative electroencephalography (EEG) monitoring tools lack spatial and temporal specificity, creating a need for interpretable biomarkers. We prospectively analyzed…

To demonstrate the feasibility of whole-brain multidimensional T_1_-T_2_ relaxation imaging on a portable 0.064 T MRI scanner. A two-dimensional inversion-recovery, fast spin-echo acquisition was used to jointly encode T_1_ and T_2_ relaxation. Joint relaxation distributions were reconstructed voxel-wise using…

1.1### Alcohol's Effects on the Brain Heavy alcohol use is known for its detrimental effects on cognitive functioning and association with alterations in cerebral gray and white matter volumes (Heikkinen et al. ; Karoly et al. ; Squeglia and Gray ). There is also increasingly more research on how acute alcohol…

By comparing the brain regions of the two groups after acupuncture intervention, it was found that the acupuncture group has a higher level of brain activity in the right precentral gyrus and right precuneus. We also found that acupuncture at GB44 can enhance the brain activity of the left postcentral gyrus and left…

1## Introduction Disorders of consciousness (DoC) represent a pathological condition marked by significant impairment in both the level and content of awareness, resulting from traumatic or non-traumatic brain injury. According to illness duration, DoC are categorized as acute or prolonged, with prolonged cases…
