UC Berkeley team builds ‘semantic atlas’ of the human brain

UC Berkeley team builds ‘semantic atlas’ of the human brain Now, using voxel-based mapping, a team of UC Berkeley researchers have pinned down the brain regions where we handle certain topics and ideas: a 3D semantic atlas of the brain.Second, the timestamping let the team model brain activity as a function of what word was heard, creating a predictive map.

Neuroscientists just isolated the part of the brain that controls free will

Neuroscientists just isolated the part of the brain that controls free will “How do we peek into people’s brains and find out how we make choices entirely on our own?” asked Susan Courtney, a professor of psychological and brain sciences and coauthor of the report.

This is your brain on physics: Scientists figure out how humans learn abstract concepts

This is your brain on physics: Scientists figure out how humans learn abstract concepts Scientists from CMU report that the brain handles scientific abstractions “using inherent, re-purposed brain systems,” according to Robert Mason, coauthor of their latest study.Then they fed those brain scans into a machine learning model, and found that the brain lit up in certain places in response to certain physics concepts, regardless of which person was doing the contemplating.

People born blind do math with their visual cortex

People born blind do math with their visual cortex When blind people read Braille, for example, their visual cortex becomes active, and deaf cats repurpose some auditory cortex to visually locate things in 3D space.When researchers compared fMRI scans from 17 people blind since birth to those of 18 people born with sight, they observed both groups’ occipital cortex lighting up when parsing sentences describing math problems.
