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.

The Human Connectome Project zeroes in on the firmware of the brain

The Human Connectome Project zeroes in on the firmware of the brain “The brain is not like a computer that can support any operating system and run any software,” says neuroscientist David Van Essen, Principal Investigator of the Human Connectome Project.“Instead, the software — how the brain works — is intimately correlated with the brain’s structure — its hardware, so to speak.

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.

Scientists isolate the brain’s ‘physics engine,’ could lead to faster, more agile robots

Scientists isolate the brain’s ‘physics engine,’ could lead to faster, more agile robots Now, for the first time, Johns Hopkins scientists have located the part of the brain responsible for this basic, fundamental processing.These brain regions are also part of the multiple demand network, a widespread set of functional areas.

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.

New probe measures electrical activity of hundreds of individual neurons in living brains

New probe measures electrical activity of hundreds of individual neurons in living brains To move beyond historically difficult and damaging methods of taking these readings, researchers from Caltech have demonstrated a minimally invasive probe for doing in vivo electrophysiology: real-time electrical recordings of living nerves in the brain.The probe can measure electrical activity in three dimensions, which could be a huge breakthrough for our understanding of cognition and neural activity.

Research ethics board halts zombie apocalypse ahead of time

Research ethics board halts zombie apocalypse ahead of time While the zombie apocalypse is a fun topic for speculation, comparatively few people actually believe that it could happen.Jokey comments aside, a planned research trial to reanimate “living cadavers” has been halted by the Indian research ethics board, amid a cloud of fatal problems with the study.
