Brain Cells' Long Migration
Neurons follow blood-vessel highways to make their way across the brain.
Like plump little caterpillars inching along a branch, newly born neurons in the adult brain appear to crawl along nearby blood vessels to find their way to their final destination.
Scientists have long known that nascent neurons, born in a spot called the subventricular zone towards the back of the brain, must find their way to the most anterior portion of the brain, the olfactory bulb. Using real-time video imaging, scientists from Quebec discovered that these neurons navigate the brain using blood vessels as paths. In the video above, published online in the Journal of Neuroscience, neurons are labeled in green, and the blood vessels in red.

Further I am all for the liquid battery technology that has emerged. We may go far with this and cell, as they are very close and absorbing materials.
The Micro has really given to us no one has ever done. Call this a gif that we keep on developing daily and one day we will have a better world for our children. I am all for more of the VR at the moment.
I thank you
