The Transmitter: Neuroscience News and Perspectives

Matthew C. Rosen and David J. Freedman survey research on where cognition occurs and why “cognitive variables are reflected broadly but not ubiquitously across the brain, including, to a surprising degree, in regions engaged in controlling movement.”

Artificial neural networks reuse information across different tasks. Sina Tafazoli et al. find that the brain takes a similar approach, performing multiple tasks by “compositionally combining task-relevant neural representations.”
