Joint-Space Empowerment: Discovering Low-Dimensional Action Manifolds for Dexterous Manipulation

Whole-brain, all-optical interrogation of neuronal dynamics underlying gut and vascular interoception in zebrafish

To select behaviors appropriate to their circumstances and needs, animals integrate information about the external environment with information about the state of their bodies, derived from sensing and processing internal signals (interoception). However, the brain-wide circuit activity underlying interoception and its...

Attraction to hierarchical feature memory explains orientation bias

When recalling the orientation of recent stimuli, observers are systematically biased away from the cardinal axes. The prevailing explanation is that this''anti-cardinal bias''arises because cardinal orientations are encoded with greater neural resources and therefore less noise, consistent with efficient coding of env...
