(Medical Xpress)—Among the most abundant of the immune system's first responders, neutrophil granulocytes comprise up to 75 percent of the body's white blood cells. During the acute phase of inflammation, neutrophils migrate ...
(Medical Xpress)—The well-behaved neuron receives signals through its many dendrites to generate spikes on a single axon. The electrical energy of these signals is generally believed to be integrated at the cell body and ...
(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, ...
In study published today in Science, researchers at NYU Langone Medical Center show for the first time that sleep after learning encourages the growth of dendritic spines, the tiny protrusions from brain cells that connect ...

(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 ...
(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 ...
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 ...
