Associative and non-associative learning mechanisms summate to produce robust and complex conditioned behavior profiles, opening new avenues to in-depth investigations of defensive responses and threat evaluation.

Echolocating toothed whales can detect and react to sudden prey movements during close approaches with speeds similar to ultra-fast tracking responses in human vision.

Gaining genetic control over neural modules that drive the grooming of each Drosophila body part reveals how mechanisms for selecting among competing behavioral choices are used to generate sequences of actions.

DeepEthogram automatically classifies animal behavior videos into researcher-defined behaviors of interest, saving researcher time and enabling more detailed downstream analysis of behavior.

Comprehensive behavioral ethograms reveal a fear conditioned cue to elicit a temporally organized suite of behaviors spanning freezing, locomotion, rearing, and jumping.

Complex motor behaviors can be assembled from simpler repeating elements controlled by pattern-generation circuits operating at different time scales.

Sexual arousal, exposure to aphrodisiac pheromones, or mere activation of peripheral pheromone-sensing neurons can modulate sleep homeostasis and are able to counteract the effects of sleep deprivation in Drosophila.

Calcineurin inhibition has opposing effects on Caenorhabditis elegans lifespan and survival on pathogens via its role in the defecation motor program.

Harbor porpoises dynamically control biosonar field of view as they track and capture prey, focusing the beam through deformations to the melon.

Drosophila grooming is driven by two internal programs.
