Latest Cerebral cortex Stories
The size and shape of the human cerebral cortex, an evolutionary marvel responsible for everything from Shakespeare's poetry to the atomic bomb, are largely influenced by mutations in a single gene.
By shedding new light on how cells migrate in the developing brain, researchers at Fred Hutchinson Cancer Research Center also may have found a new mechanism by which other types of cells, including cancer cells, travel within the body.
Model of Rett syndrome suggests a deficit in processing cues from the environment.
Scientists are developing a technique to map both the connections and functions of nerve cells in the brain together for the first time, bringing them closer to creating a computer model of the human brain.
Researchers seeking to unravel the most ancient yet least understood of the five senses â€“ smell â€“ have discovered a previously unknown step in how odors are detected and processed by the brain.
A new study is providing fascinating insight into how projections conveying sensory information in the brain are guided to their appropriate targets in different species.
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.
Dr. Olivier Collignon of the University of Montreal's Saint-Justine Hospital Research Centre compared the brain activity of people who can see and people who were born blind, and discovered that the part of the brain that normally works with our eyes to process vision and space perception can actually rewire itself to process sound information instead.
The brain is a black box.
Human social interactions are shaped by our ability to recognize people.
Formation and Orientation The development of the brain is broken down into stages. The basic evolution begins in the third week of the embryonic process where the neural plate is formed. By week four, the neural plate has developed into the neural tube. The anterior part of the tube, the telencephalon, grows rapidly as it prepares to later give way to the brain. As time goes on, cells begin to classify themselves as either neurons or glial cells, thus determining their functions. Glial...
