It’s time to examine neural coding from the message’s point of view

In studying the brain, we almost always take the neuron’s perspective. But we can gain new insights by reorienting our frame of reference to that of the messages flowing over brain networks.

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.

Most neurons in mouse cortex defy functional categories

The majority of cells in the cerebral cortex are unspecialized, according to an unpublished analysis—and scientists need to take care in naming neurons, the researchers warn.

Escaping groupthink: What animals’ behavioral quirks reveal about the brain

Neuroscientists have long ignored the variability in animals’ behavioral responses in favor of studying differences across groups. But work on the brain differences that underlie that variability is beginning to pay off.
