Brain Research: Brain's immune system could be harnessed to fight Alzheimer's ♦ Spot on for brain research: Controlling nerve cells with light

Chemotherapy-induced hearing loss affects neurocognition in pediatric brain tumor survivors Platinum-based chemotherapy may not only impact hearing, but that the hearing loss may then contribute to long-term neurocognitive deficits.
Spot on for brain research: Controlling nerve cells with light Gero Miesenböck was the first to insert a light-controlled on/off switch into brain cells. His pioneering method allows scientists to switch nerve cells on and off selectively and observe how the behavior of, for example, fruit flies or mice changes as a result. In this way, researchers can learn in a step-by-step process what behavior the studied brain circuits control and what goes awry in disease
Brain imaging reveals possible depression signature in traumatic brain injury Individuals with depression in addition to traumatic brain injury (TBI) are prone to poorer recovery, reductions in cognitive performance, greater functional disability, increased suicide attempts and other social and sexual difficulties. Since depression symptoms vary greatly, teasing apart a diagnosis in the context TBI is often difficult. However, researchers have identified a potential brain-based biomarker for depressive symptoms that could simplify the process

Brain's immune system could be harnessed to fight Alzheimer's The brain's immune system could potentially be harnessed to help clear the amyloid plaques that are a hallmark of Alzheimer's disease, new research suggests. The findings are the culmination of years of investigation after a surprising discovery while studying mouse models of Alzheimer's disease. Researchers observed that amyloid beta plaques -- which scientists believe play a major role in the disease -- were being cleared in animals with chronic brain inflammation
