Microglia: the movers and shakers of the brain

(Medical Xpress)—Once the brain has fully developed, its neurons and astrocytes remain relatively fixed. There are a few select migratory streams that replenish vulnerable populations with dedicated stem cell recruits, ...

The control of dendritic branching by mitochondria

(Medical Xpress)—A fundamental difference between neurons in real brains and those in artificial neural networks is the way the neurons in each are connected. In artificial nets, the synapses between neurons often have ...

Volitional control from optical signals

(Medical Xpress)—In their quest to build better BMIs, or brain-machine-interfaces, researchers have recently begun to look closer at the sub-threshold activity of neurons. The reason for this trend is that with only a limited ...

Neuroscientists discover new 'mini-neural computer' in the brain

Dendrites, the branch-like projections of neurons, were once thought to be passive wiring in the brain. But now researchers at the University of North Carolina at Chapel Hill have shown that these dendrites do more than relay ...
