Cortical neurons seem to receive about the same amount of excitation and inhibition. One of the founders of this key idea in 1990s explains.

Diving in with Nachum Ulanovsky
With an eye toward realism, the neuroscientist, who has a new study about bats out today, creates microcosms of the natural world to understand animal behavior.

Successful wayfinding requires an "internal compass" – a representation of the direction we're facing. Where is this internal compass in the brain?
When humans navigate a virtual city, the retrosplenial complex & superior parietal lobe keep track of facing direction across distinct environments.

Mice still outperform our best computing machines in some ways. One way is robust visual processing.
