Thousands of axons grew from the transplants and connected to damaged primate tissue, the first such demonstration in primates.

Researchers swap microscopy for RNA sequencing to track neural paths in the mouse brain.
 

Barcodes of mRNA travel to the cells' axon terminals, offering a sequencing-based approach to neural mapping.

Camillo Golgi’s black reaction revealed, for the first time, the fine structures of intact neurons, which he captured with ink and paper.

Glial cells consume mitochondria released by neurons in the optic nerve.
