High-resolution blood oxygen level-dependent functional magnetic resonance imaging enables brain-wide mapping of activated regions during sensory stimulation in awake mice, including associated areas, for high-order sensory processing including anticipation responses.
Electric signals produced by weakly electric gymnotiform fish, long seen as communication attempts, may also serve to localize conspecifics, revealing a distinct functional role.
While monitoring neuronal activity in freely moving Drosophila is challenging, HI-FISH enables brain-wide mapping of active neurons and reveals behavior-specific neural activity.

Bespoke volumetric calcium imaging, validated with neuropixels recordings, evidence a population code for sound azimuth at the dorsal cortex of the inferior colliculus, with a contribution of noise correlations.

Mice can use self-motion cues to learn a cognitive map thereby permitting them to take shortcut trajectories in an open maze without requiring prior experience of such routes.
