Most people assume humans only have two brain hemispheres—but we actually have four brain hemispheres. There are two "big" hemispheres in the cerebrum that house the cerebral cortex and are commonly ...

The left and right cerebral hemispheres are colloquially referred to as "left brain-right brain." The cerebral cortex (Latin for "bark") that encases each hemisphere contains a layer of gray matter ...

Researchers have developed a new combination of technologies that allows them to identify the functional properties of individual synapses that link the two hemispheres and determine how they are ...

The cerebral cortex of your brain is the outermost layer. It's the part of the brain that appears wrinkled because it has a lot of folds. Your cerebral cortex is divided into two hemispheres. Each ...

Upper left panel. A cross-sectional image of the ferret brain. Some neurons of the cerebral cortex (blue) are dyed green with GFP, green fluorescent protein. Upper right panel. The rectangle with ...

The brain adapts, through reorganization, in people born without a corpus callosum who lack a bridge between the two cerebral hemispheres. It is thought that these mechanisms enable the brain to ...

One in 4,000 people is born without a corpus callosum, a brain structure consisting of neural fibers that are used to transfer information from one hemisphere to the other. A quarter of these ...

This metaphorical illustration reimagines a hidden view of the brain of a patient with hemispherotomy. In the absence of subcortical activating inputs, the disconnected cortex defaults to a sleep-like ...

Researchers at The Picower Institute for Learning and Memory at MIT report that Alzheimer’s disease disrupts at least one form of visual memory in mice by degrading a newly identified circuit that ...

The brain divides vision between its two hemispheres-what's on your left is processed by your right hemisphere and vice versa-but your experience with every bike or bird that you see zipping by is ...
