Researchers use 3-dimensional electron microscopy to map the local connectome in the cerebral cortex. Mammalian brains, with their unmatched number of nerve cells and density of communication between them, are the most complex networks known. While methods to analyze neuronal networks sparsely, accessing about one in every ten-thousandth nerve cell has been available for decades, … Continue reading Deep Inside the Brain: Unraveling Dense Networks in the Cerebral Cortex [Video]
