Caffeine and its analogues revert memory deficits by normalizing stress responses in the brain

A study published in the journal Scientific Reports from Nature publishing group, describes the mechanism by which caffeine counteracts age-related cognitive deficits in animals.

The study coordinated by Portuguese researchers from Instituto de Medicina Molecular (iMM Lisboa) and collaborators from Inserm in Lille, France, along with teams from Germany and United States, showed that the abnormalexpression of a particular receptor – the adenosine A2A, target for caffeine – in the brain of rats induces an aging-like profile namely memory impairments linked to the loss of stress controlling mechanisms.

Artificial retinas: promising leads towards clearer vision

A major therapeutic challenge, the retinal prostheses that have been under development during the past ten years can enable some blind subjects to perceive light signals, but the image thus restored is still far from being clear. By comparing in rodents the activity of the visual cortex generated artificially by implants against that produced by “natural sight”, scientists from CNRS, CEA, Inserm, AP-HM and Aix-Marseille Université identified two factors that limit the resolution of prostheses. Based on these findings, they were able to improve the precision of prosthetic activation. These multidisciplinary efforts, published on 23 August 2016 in eLife, thus open the way towards further advances in retinal prostheses that will enhance the quality of life of implanted patients.
