Grasp Brain Organization Is Restored After Hand Transplantation

A new study shows that higher-level regions of the brain may compensate for persistent reorganizational changes in brain areas responsible for hand sensation and movement following a hand transplant. When a person loses a hand, nerves that control sensation and movement are severed. This trauma deprives sensory and movement areas of the brain of stimulation, […]

Distant Brain Regions Selectively Recruit Neural Stem Cells

Long-distance brain connections can target discrete pools of stem cells in their niche and stimulate them to divide and produce specific subtypes of olfactory bulb neurons, researchers at the Biozentrum of the University of Basel report. Our brain generates new neurons throughout life. A diversity of stimuli promotes stem cells in their niche to form […]
