The lopsided brain: Attention bias is shared by humans and birds

...ct is somewhat surprising, given that birds lack a corpus collosum, the structure in human brains that is th...mispheres. In the past, such communication via the corpus collosum has been thought to form the basis for asymmetries in human spatial attention, but the new ...

MIT research holds promise for Huntington's treatment

...a. Normally, the dopamine transmits signals to the corpus striatum, allowing muscles to make smooth, controlled movements. When those dopamine-producing cells die, Parkinson's patients exhibit the tremors that are characteristic of the disease. The researchers are now working on finding a more potent versi...

New tool tracks brain development in babies

...urbed in several areas of the brain, including the corpus callosum, which allows communication between the two hemispheres of the brain, and, most significantly, the corona radiata, which is associated with finely coordinated movement. Six of the 10 infants continued to exhibit disturbed fiber patterns at f...

Queensland scientists identify molecule that links both sides of the brain

...ch provided new clues regarding development of the corpus callosum, the main connecting nerve tract that shu...d a molecule that helps control development of the corpus callosum. The corpus callosum has millions of individual nerve fibres. If these fibres fail to rea...

Carnegie Mellon researchers discover key deficiencies in brains of people with autism

...people with autism, as well as smaller size of the corpus callosum, the white matter that acts as cables to ...ain. They have discovered that key portions of the corpus callosum seem to play a role in the limitation on synchronization. In people with autism, anatomical...

Study of gene transfer for erectile dysfunction shows promise

...egments ?mixed into plasma ?were injected into the corpus cavernosum, expandable tissue along the length of the penis that fills with blood during erection. A variety of clinical and laboratory tests were used to assess safety. In addition, effectiveness was measured using the International Index of Erectil...

Brain's white matter -- More 'talkative' than once thought

...ed activity from individual precursor cells in the corpus callosum, a region of white matter that connects the two brain hemispheres. To their surprise, OPCs were found to have electrical signals produced by the neurotransmitter glutamate, similar to the signals used as the principle means of cell-to-cell c...
