Revealing how experts’ minds tick
Primates, particularly humans, are set apart from other vertebrates by more than a huge expansion of the cerebral cortex, the region of the brain used for thinking. The connection and coordination of the cerebral ...

First MR images to show complete borders in human cerebral cortex
Understanding functional properties of the brain’s structural units is one of the main aims of brain research. Until now only fragmentary borders of brain areas could be identified in vivo since the resolution ...

Digital versus analog control over cortical inhibition
In the cerebral cortex, the balance between excitation (pyramidal neurons) and inhibition (interneurons) is thought to be mediated by the primary mode of neuronal communication: "all-or-none" action potentials, or spikes. ...

Web-crawling the brain
The brain is a black box. A complex circuitry of neurons fires information through channels, much like the inner workings of a computer chip. But while computer processors are regimented with the deft economy of an assembly ...

Abnormal neural activity recorded from the deep brain of Parkinson's disease and dystonia patients
Movement disorders such as Parkinson's diseases and dystonia are caused by abnormal neural activity of the basal ganglia located deep in the brain. The basal ganglia are connected to the cerebral cortex in the brain surface ...

Researchers have found how brain cells control their movement to form the cerebral cortex
A study led by Academy Research Fellow Eleanor Coffey identifies new players that put the brakes on. They show in mice that lack the star player "JNK1", that newborn neurons spend less time in the multipolar stage, which ...
