Can an emerging field called ‘neural systems understanding’ explain the brain?

This mashup of neuroscience, artificial intelligence and even linguistics and philosophy of mind aims to crack the deep question of what "understanding" is, however un-brain-like its models may be.

Dancing in the dark: Honeybees use antennae to decode nestmates’ waggles

The insects align their antennae with their body’s angle to a dancer—information that vector-processing circuitry in the brain deciphers into a flight path, a new study suggests.

What ‘drifting representations’ reveal about the brain

How neuronal activity patterns associated with a behavior can change, even when the behavior does not — something once seen as an experimental artifact — could offer new insights about neural function.
