"Across five PEERS experiments, 300+ subjects contributed more than 7,000 90 minute memory testing sessions with recorded EEG data. Here we tell the story of PEERS: its genesis, evolution, major findings, and the lessons it taught us about taking a big science approach to the study of memory and the human brain."

"We achieved these goals through a 10 year data collection effort"

Европейский Human Brain Project не особо продвинулся в раскрытии тайн мозга, но породил открытую платформу для исследователей мозга под названием EBRAINS. Ей (а заодно и сложности мозга) посвящена большая статья в журнале открытого доступа eNeuro:

"To render data, tools and methods, theories, basic principles and concepts interoperable, the Human Brain Project (HBP) has launched EBRAINS"

"a distributed, digital infrastructure, EBRAINS (https://ebrains.eu/) ... is an open platform for researchers, offering technologically mature tools and services"

"EBRAINS is offering tools and services in the field of data and knowledge (https://ebrains.eu/services/data-and-knowledge), atlases (https://ebrains.eu/services/atlases), simulation (https://ebrains.eu/services/simulation), brain-inspired technologies (https://ebrains.eu/services/brain-inspired-technologies), medical data analytics (https://ebrains.eu/services/medical-data) as well as a platform for collaboration (https://ebrains.eu/services/community)."

"Here we assemble an interactive open resource to benchmark brain morphology derived from any current or future sample of MRI data (https://www.brainchart.io/). With the goal of basing these reference charts on the largest and most inclusive dataset available, acknowledging limitations due to known biases of MRI studies relative to the diversity of the global population, we aggregated 123,984 MRI scans, across more than 100 primary studies, from 101,457 human participants between 115 days post-conception to 100 years of age. MRI metrics were quantified by centile scores, relative to non-linear trajectories of brain structural changes, and rates of change, over the lifespan. Brain charts identified previously unreported neurodevelopmental milestones, showed high stability of individuals across longitudinal assessments, and demonstrated robustness to technical and methodological differences between primary studies."
