A recent study found that the 2 most popular apps were missing around 20 of the available listings in any given market. Millions mapped has the vast majority of for sale and for rent listings in the United States. The software is the subject of a court case taken by MEP Patrick Breyer to the European court of justice in Luxembourg, arguing that there should be more public scrutiny of such technology.

They’re areas that the corporations operating there should have protected in the first place but failed to, Connolly said of the newly mapped parcels. The last trial finished in late 2019 and was hailed as a success by the EU but academics have called it pseudoscience, arguing that the “micro-expressions” the software analyses cannot be reliably used to judge whether someone is lying. About three million hectares including rare inland rainforests found only in B.C., Russia’s far east and Siberia are available for logging. A machine scans refugees and migrants’ facial expressions as they answer questions it poses, deciding whether they have lied and passing the information on to a border officer. “It’s on a scale where we probably will be able to do that within a decade, I suspect.” Dulac wants to see how the cortex links to other parts of the brain, and mapping the mouse brain would reveal that.The EU spent €4.5m (£3.8m) on a three-year trial of artificial intelligence-powered lie detectors in Greece, Hungary and Latvia. “A whole mouse brain is only 1000 times bigger than this, an exabyte instead of a petabyte,” says Lichtman. Jain, Dulac and Lichtman were part of a group that, in 2020, argued in favour of mapping an entire mouse brain at a similar level of detail. Nobody knows why.īrain mapping, or connectomics, has come a long way since its first breakthrough in the 1980s, when researchers mapped the 302 neurons in the nervous system of a worm called Caenorhabditis elegans. “The two cells pointed in exactly the opposite direction on the same axis,” says Lichtman. The team also found mysterious pairs of neurons deep in the cortex that hadn’t been observed before. The super-strong connections would allow a message to pass swiftly through the network. “There’s lots of things your brain does by cognition, by thinking and puzzling it out and making a decision, and there are many things you do automatically that could not have come genetically,” he says, such as braking when you see a red light. It isn’t clear why, but Lichtman speculates that the multi-synapse connections underlie learned behaviours. But there were also some tendrils that formed up to 20 synapses onto one target neuron, meaning this tendril by itself would probably be able to trigger that neuron to fire. Data infrastructure platform maker Mapped has raised an additional 6. Normally, when a tendril from one neuron passed close to another, it would form just one synapse, or more rarely two to four. The team has already made new discoveries about how our brain is wired: for example, there was a stark discrepancy in the numbers of connections between neurons. “It’s interesting to uncover all the stuff under the hood of one pixel of an MRI.”įor Dulac, the data set is “a trove of goodies for years to come”. “The entire data set we produced is a cubic millimetre, which is usually one pixel in an MRI scan,” he says. Jain says its scale is best understood by thinking of a functional magnetic resonance imaging (fMRI) scan, used to show activity in different brain regions.

They used machine learning to reconstruct the tendrils linking one neuron to another and labelled the different cell types. Finally, they cut it into slices around 30 nanometres thick, or about one-thousandth the width of a human hair, and used an electron microscope to image every slice.Īt this point, Jain’s team at Google took over, assembling the two-dimensional slices – which Jain calls “a deli slicer approach to the brain” – to form a three-dimensional volume. Then they embedded it in resin to toughen it. Lichtman and his team immediately immersed the sample in preservatives, then stained it with heavy metals like osmium, so the outer membranes of every cell were visible under an electron microscope. To do this, the surgeons had to remove some healthy brain tissue that overlaid the hippocampus. She underwent surgery to remove the left hippocampus, the source of her seizures, from her brain. This mammoth undertaking began when a team lead by Jeff Lichtman, also at Harvard University, obtained a tiny piece of brain from a 45-year-old woman with drug-resistant epilepsy. ![]() “There’s something just a little emotional about it.” ![]() It is the first time we have seen the real structure of such a large piece of the human brain, says Catherine Dulac at Harvard University, who wasn’t involved in the work.
