Scientists Show How Nerve Wiring Self-Destructs
Researchers have discovered a way in which the body can remove injured axons. They also identified a potential target for new drugs which could prevent the inappropriate loss of axons, as well as maintain nerve function.
Experience Leads to the Growth of New Brain Cells
Researchers examine how individuality develops through adult neurogenesis; the generation of new neurons in the hippocampus which allows the brain to react flexibly to new information.
Cocaine Vaccine Passes Key Testing Hurdle
Researchers have successfully tested a new vaccine in primates to battle cocaine addiction. Using neuroimaging techniques, they demonstrated the vaccine prevents cocaine from reaching the brain and producing a dopamine induced high. Human trials could begin within the next year.
Sense of Touch Reproduced Through Prosthetic Hand
Artificial sensors in a prosthetic hand allows rhesus macaques to sense tactile stimulus, according to a new study. A similar device could be used in human trials within the next year, researchers hope.
Researchers Discover Dynamic Behavior of Progenitor Cells in Brain
Monitoring progenitor cells in the brains of living mice, researchers discover these cells remain highly dynamic in the adult brain. Progenitor cells can transform into cells that insulate nerve fibers and help form scars that aid in tissue repair, study suggests.
