That is a bit interesting that our own brain can do this to help make sure the parts of it that needs the most nutrients gets exactly that.

That's so very cool. The human body is absolutely a miracle. If only it could monitor it to the point where it could cut off circulation to a critical point, like a stroke, prior to the stroke. Of course, it'd still have to fix the area prone to a stroke.
Fluctuation in the concentration of calcium ions contributes to brain shape
The first step in shaping the brain is that the neural plate, a sheet-like cell layer, curves to form the neural tube. Scientists have now shown that during the process of neural tube formation a transient increase in the concentration of calcium ions in cells causes these morphological changes and is essential for neural tube formation.

Closer look at brain circuits reveals important role of genetics
New clues to the wiring of the brain have now been uncovered by a team of researchers. They found that neurons in brain regions that store memory can form networks in the absence of synaptic activity. Ref. Source 2s.
Brain development and aging. The brain is a complex organ -- a network of nerve cells, or neurons, producing thought, memory, action, and feeling. How does this complex system change from childhood to adulthood to late life in order to maintain optimal behavioral responses? These questions were put to the test by psychologists who studied hundreds of fMRI brain scans, from two separate datasets, to see how the variability of brain signals changes or remains the same during a human lifespan.

Brains evolved to need exercise. Mounting scientific evidence shows that exercise is good not only for our bodies, but for our brains. Yet, exactly why physical activity benefits the brain is not well understood. Researchers suggest that the link between exercise and the brain is a product of our evolutionary history and our past as hunter-gatherers. Source 5m.
