Olcese and the rest of the research team (which involved researchers from the European CANON project and that was led by Prof. Cyriel Pennartz, who participates in the European Flagship Human Brain Project) have discovered that not all forms of communication within the cerebral cortex are lost during non-REM sleep. Specifically, correlations are preserved between neurons located within individual regions and between some subpopulations of neurons located in different cerebral areas. To reach these conclusions, published in ‘The Journal of Neuroscience’, the researchers studied how the brain regulates the neuronal connections of the neocortex and hippocampus in rats.
Advances in the study of consciousness
In a second investigation published in the same journal, a team of investigators from the Human Brain Project and the CANON project analysed the state of consciousness from a neuroscience perspective. Although historically this concept has been studied from a philosophical standpoint, experts have reviewed various scientific studies which reflect the importance of a proper communication between cortical areas in the process. “Neuroscientific research on consciousness driven by new methods and theoretical advances should be increasingly robust and accepted, since notable scientific and clinical progress is now starting to be made,” the authors pointed out. The CANON project is a partnering project of the Human Brain Project, one of the Future Emerging Technology Flagship Initiatives (FET Flagships) of Horizon 2020 – the European Union framework programme for financing research. Inserm (the French National Institute of Health and Medical Research) and the Wigner Research Centre for Physics (Hungary) participate in the CANON project alongside the University of Amsterdam.
