@MichelTdS and I wrote a #review on the last decade of #brain #connectivity #research for a special issue in @ScienceMagazine : 'circuits create networks by stringing together many brain regions to orchestrate brain symphony conducted by finely attuned connections.' A 🧵 First things first, the #cover shows that the corpus callosum has different axonal calibres, as shown in a cross-section of the axons. Warmer colours (red-yellow) indicate thicker axons. These finely attuned connections allow for the perfect orchestration of the brain symphony.
