61 “DAWN’S LEFT HAND,” as Persian poet Omar Khayyám called the zodiacal light, gently illuminates the eastern sky just before morning twilight in the autumn.

If signals can travel extensively through astrocyte circuits, then glia at one site could activate distant glia to coordinate the firing of neural networks across regions of the brain. Comparisons of brains reveal that the proportion of glia to neurons increases greatly as animals move up the evolutionary ladder. Haydon wonders whether extensive connectivity among astrocytes might contribute to a greater capacity for learning. He and others are investigating this hypothesis in new experiments. Perhaps a higher concentration of glia, or a more potent type of glia, is what elevates certain humans to genius.
