A principled statistical segmentation of fruit fly walking leads to a compact model of immediate actions that can reproduce the unique behavioral sequences of individual flies.

A high-throughput behavioral paradigm and computational modeling are used to decompose olfactory navigation in walking Drosophila melanogaster into a set of quantitative relationships between sensory input and motor output.

A simple, computationally efficient method provides spatiotemporally precise optogenetic perturbations in freely walking Drosophila, revealing the asymmetries and region-specificity of behavioral programs evoked by activating mechanosensory and chemosensory neurons.

Visualized odor encounters show that Drosophila navigate spatiotemporally complex odor plumes using random walks biased by the timing of brief and unpredictable odor encounters.

Hemilineages link neuronal stem cells to behavioral functions by providing a conserved ground plan of neuronal types that evolution then uses to sculpt different types of walking and flight behaviors.

In the fly, Drosophila melanogaster, the population activity of descending neurons (DNs) projecting from the brain to the motor system is predominantly correlated with locomotion with only a few DNs encoding grooming or olfactory signals in the absence of behavior.

Turning in an insect is the combined result of body-side-specific modifications in processing of local sensory feedback, and modification of local central pattern generator activity.

The novel Reach Cage allows neurophysiology studies of structured behavior with unrestrained Rhesus macaques showing that the frontoparietal reach network is selective for reach goals outside the immediately reachable space.

Optogenetically activated individual descending neurons in Drosophila melanogaster drive varied stereotyped motor patterns that are often influenced by the animal's initial behavioral state.

Neurons called lobula columnar cells help fruit flies respond appropriately to specific visual cues, such as those signaling an approaching predator.
