[PDF][PDF] A circuit for gradient climbing in C. elegans chemotaxis
Animals have a remarkable ability to track dynamic sensory information. For example, the
nematode Caenorhabditis elegans can locate a diacetyl odor source across a 100,000-fold …

[HTML][HTML] Serotonin and the neuropeptide PDF initiate and extend opposing behavioral states in C. elegans
Foraging animals have distinct exploration and exploitation behaviors that are organized into
discrete behavioral states. Here, we characterize a neuromodulatory circuit that generates …

[PDF][PDF] Neural circuitry for stimulus selection in the zebrafish visual system
When navigating the environment, animals need to prioritize responses to the most relevant
stimuli. Although a theoretical framework for selective visual attention exists, its circuit …

[PDF][PDF] Biological motion as an innate perceptual mechanism driving social affiliation
Collective behavior, such as shoaling in teleost fish, is driven by the perceptual recognition
of conspecific animals. Because social interactions are mutual, it has been difficult to …

Oscillatory stimuli differentiate adapting circuit topologies
Biology emerges from interactions between molecules, which are challenging to elucidate
with current techniques. An orthogonal approach is to probe for 'response signatures' that …

[PDF][PDF] Rapid effects of selection on brain-wide activity and behavior
Interindividual variation in behavior and brain activity is universal and provides substrates
for natural selection [1–9]. Selective pressures shift the expression of behavioral traits at the …
