Google Is Using AI to See Inside the Brain Like Never Before
JULY 16, 2018
Neuroscientists have a lot of data on the brain—we can see it, take pictures of it, study it. But for all the data, the brain’s workings are still relatively unknown.
A new paper published in Nature Methods might help neuroscientists better understand the structure of the brain and how it functions, according to research scientists from Google. A Google team trained an artificial neural network, the kind of AI perfect for automating simple human tasks, to sift through 663 GB of images of a zebra finch’s brain and construct a 3D model of every neuron and synapse.
“The real impact of this is the amount of neuroscience that can be done,” Viren Jain, a Google co-author on the paper who has been researching this automated neuronal structure problem for 12 years, told Quartz. “One thing that historically neuroscientists haven’t had access to is being able to study the actual patterns of neurons in the brain in a comprehensive way.”
The data that the AI crunched came from an electron microscope, and the data isn’t actually incredibly new. The Max Planck Institute, the German research center, collaborated with Google on the project and provided the data, which it’s had since 2012. It’s easiest to think of the data as thousands of 2D images showing a slice of the brain. When stacked on top of each other, they make a 3D image.
