Artificial intelligence to decode thoughts

Despite recent advances in brain imaging, the brain’s representation of the visual world is still largely unknown. Using a new artificial intelligence technique - deep learning - to decode brain activity recorded in functional imaging, CerCo’s Rufin VanRullen and Leila Reddy can reconstruct images seen - or imagined - by subjects. This method, published in Nature Communications Biology, opens the door to new explorations of the brain.

increased oxidation of iron, RNA and dystrophic microglia in the brains of older male marmosets.

Featured Articles

The editorial team of the American Journal of Primatology has chosen to highlight the following article: Loss of ferritin-positive microglia relates to increased iron, RNA oxidation, and dystrophic microglia in the brains of aged male marmosets Juan de Dios Rodríguez-Callejas, Daniel Cuervo-Zanatta, Abraham Rosas-Arellano, Caroline Fonta, Eberhard Fuchs, Claudia Perez-Cruz Volume 81, Issue 2, February 2019->https://onlinelibrary.wiley.com/doi...] This paper, which involves a CERCO researcher, presents how ferritin provides microglia protection in adult and elderly marmosets, while in elderly subjects, the decline in ferritin and the increased amount of iron in brain tissue may be related to the increase in the number of cells with oxidized RNA, possibly associated with the development of neurodegeneration...

Waves in the brain

Brain activity is structured into brain rhythms that differ in frequency, with different frequencies reflecting different mental states. But these brain waves, especially the alpha waves at 10Hz, also have functional roles that still need to be clarified.

By recording brain activity on the surface of the scalp and using electroencephalographic and mathematical techniques of inverse correlation, Rufin VanRullen and Diego Lozano-Soldevilla showed that alpha waves were true "perceptual echoes" propagating over several cycles and in a very precise organization. This organization makes it possible to postulate that perceptual echoes behave like "radar screens" that would scan the visual field rhythmically every 100ms, thus making it possible to locate an object in space and time; each position in the surrounding space is scanned at different times and in a well-defined order. These results published in Cell Reports make it possible to propose for the first time a functional role for these brain waves at 10 Hz, which would be a direct reflection of the cortical processing of sensory information.

BRAIN WEEK 2019

Brain Week 2019 will take place from March 11 to 17, 2019. This edition is placed under the high patronage of Mrs Frédérique Vidal, Minister of Higher Education, Research and Innovation. As every year, researchers and doctoral students from the CERCO laboratory (UMR 5549 CNRS/UT3) will meet the general public and schoolchildren to share their knowledge. Thus we will be able to attend the opening conference on "Brain and Music Learning" at the Mazades Theatre on Monday, March 11 at 6 p.m. with several CERCO researchers, Chloé FARRER, Muriel MESCAM and Florence REMY, or to watch a documentary on children’s brains at the ABC at 8:30 p.m. on Tuesday, March 12.
