Homology of vertebrate skull structures should be based on evolutionary continuity and an appreciation of germ layer origins and inductive signaling in the embryonic head.

A new methodology and protocol use automated brain imaging and task training technology to probe links between behavior and mouse cortical circuits.

A set of stochastic processes reproduces the mouse exploration patterns in an automated variant of the Barnes maze.

A hydrodynamic model of fish swimming in a channel predicts a critical flow speed for fish to successfully swim against a flow, unveiling a passive mechanism for rheotaxis to emerge without access to any sensory information.

A provoked awakening protocol during sleep reveals that selective bilateral hippocampal damage in humans is associated with reduced frequency, quality, and content of dreaming.

Sigma oscillations have a dual role in motor memory consolidation depending on their temporal coordination with slow waves during post-learning sleep.

A new FRET-based cAMP biosensor with nanomolar sensitivity makes it possible to measure cAMP dynamics in miniscule subcellular compartments like cilia and flagella.

Psychometric measures reveal that, contrary to common assumption, rats have good visual form discrimination capacity under red and even far-red illumination.
