About-faces in U.S. federal science funding put neuroscientists on edge

“It’s hard to know what’s real,” says neuroscientist Josh Dubnau after a dizzying week in which diversity-related grant applications were pulled from study sections only to be reinstated five days later, among other reversals.

Dmitri Chklovskii outlines how single neurons may act as their own optimal feedback controllers

From logical gates to grandmother cells, neuroscientists have employed many metaphors to explain single neuron function. Chklovskii makes the case that neurons are actually trying to control how their outputs affect the rest of the brain.
