All I ask is a long vessel and a neuron to guide her by. Its "a wild call and a clear call that may not be denied". It is well established that apart from traversing side by side in the brain", the tight coupling that exists between blood vessels and neurons is crucial for proper oxygen delivery to the brain. Technical note: The confocal image partially used for this collage art piece was provided by Dr. Edith Hamel and highlights blood vessels from a cerebellar slice immunolabeled for laminin in red.
