Ultrabrain

Brain and Pixels (EBruner)The BigBrain Project has received lot of attention: a whole human brain sectioned in 7400 slices with 20 microns thickness, stained for evidencing the cellular bodies and then digitized. An exciting success, indeed, not only for anatomical advances but also for technical and methodological challenges. Data storing and exploration is a major issue in our digital era, and I am fascinated by the numbers discussed in the paper published on Science. A recent digitized mouse brain at 1 micron resolution can be stored in 8 Terabytes. A similar attempt for a single human brain would therefore require 21.000 Terabytes! Just one specimen. Difficult to store, impossible to handle with the current technology. Computers can store a huge and amazing quantity of information, but they can roughly store or handle the information of one human brain. And we are here dealing only with the raw spatial organization. In terms of function, we are still entangled in a famous cybernetic paradox: a computer can perform incredible and unimaginable calculations, but we have not been able to make it properly … walk!

Brain Maps

brainmaps.orgBrain Maps is a huge on-line database of brain sections at extreme high resolution. Physical and digital sliced brains are available to download and to explore at macroanatomical and cellular levels. Brain atlases are interactive, and images are available for research and for teaching, with applications and annotations, in two and three dimensions. This is an amazing resource!

  • Homo erectus temporal lobes
    This week, we provide a new study of temporal lobe evolution in the Homo erectus hypodigm inferred from the middle cranial fossa (MCF) of the skull. Following from our earlier publication this year where we determined a strong reliability for MCF metrics to predict the temporal lobe volume of the brain in extant anthropoids and […]

  • The Genetics of the Transatlantic Slave Trade
    Between the 16th and 19th centuries, approximately 12.5 million people were violently deported from their homes in Africa to the Americas by slavers. As current events have shown, the destruction of communities, cultures and families have had everlasting ramifications which are felt a century and half later. Some of the less tangible pains is the... Continue […]

    Researchers at MIT have developed a new method of electrically stimulating deep brain tissues without opening the skullSince 1997, more than 100,000 Parkinson’s Disease patients have been treated with deep brain stimulation (DBS), a surgical technique that involves the implantation of ultra-thin wire electrodes. The implanted device, sometimes referred to as […]
