Researchers present NextBrain, a probabilistic histological atlas of the whole human brain, developed using AI-enabled methods to align histological sections and create delineations for 333 ROIs. A Bayesian tool is also created for automatic segmentation of these ROIs in MRI scans.
A new study published in Psychophysiology used electroencephalography (EEG) and advanced modeling to track brain dynamics during metaphor generation, finding that specific sequences of brain states are associated with more creative metaphors. Early on, higher alpha-band synchronization predicted novelty, while later, alpha-band desynchronization became more prominent.
A new brain imaging study found links between authoritarian attitudes (both left- and right-wing) and structural differences in the brain, specifically reduced gray matter volume in the dorsomedial prefrontal cortex (right-wing) and reduced cortical thickness in the right anterior insula (left-wing).
A study in Psychiatry Research: Neuroimaging found structural differences in the precuneus, a brain region associated with memory and self-focus, in individuals who tend to ruminate, which is common in depression. The findings suggest that rumination may result from network-level interactions in the brain.
