Around the turn of the 20th century, a Spanish neuroscientist named Santiago Ramón y Cajal created intricate images of intertwined neurons that changed neuroscience forever. His exquisite illustrations helped scientists understand some fundamental facts about the brain, namely that long-armed neurons, communicating over gaps called synapses, are the basic unit of the human nervous system.  Now, a team of researchers from Boston University, Harvard and the … Continue reading Researchers have developed single-cell imaging for the brain on the nanoscale.
