Why the lack of neurogenesis in adults may be an evolved positive trait in mammals. In song birds:

“... as the new neurons move through the brain, they seem to be pushing or deforming the tissue,” Scott says. “You could imagine that they might be altering the circuit, breaking connections that are the basis of stored memories.”

Songbird connectomics, from my colleague Joergen Kornfeld:

Includes the first connectome of basal ganglia.

Three key papers:
