MEG reveals how the brain processes face-like images

A brain imaging technique called magnetoencephalography (MEG) has identified a neural network that plays a key role in face pareidolia – a tendency to see faces in nonface images.

MRI reveals effects of risk factors on vulnerable brain regions

By Kate Madden Yee

MRI shows the effects particular risk factors such as diabetes, air pollution, and frequency of alcohol use have on "higher-order" brain regions located in the cerebral cortex, researchers have found.

March 27, 2024

To the left of the figure, the red-yellow color denotes the regions that degenerate earlier than the rest of the brain and are vulnerable to Alzheimer’s disease. These brain areas are higher-order regions that process and combine information coming from our different senses. To the right of the figure, each dot represents the brain data from one UK Biobank participant. The overall curve shows that, in these particularly fragile regions of the brain, there is accelerated degeneration with age. Image courtesy of Gwenaëlle Douaud, PhD, and Jordi Manuello, PhD.

PET/MRI findings ‘encouraging’ for people with late-life depression

PET/MRI scans have revealed positive findings for people with late-life depression – namely that they have preserved “synaptic density,” and thus are likely to respond to treatment, according to a group in Belgium.

March 21, 2024

PET/MRI images used in the analysis: Axial (left, through the prefrontal volume-of-interest) and coronal (right, through the hippocampal volume-of-interest) overlay of a partial volume corrected carbon-11 UCB-J PET image (right subparts) registered to the anatomical T1-weighted MRI background for delineation.
