Dwarf cuttlefish, like octopus, are masters of camouflage. To camouflage the cuttlefish brain must solve a hard computational problem; the brain needs to process the visual environment, compute an appropriate pattern, and then orchestrate the expansion and contraction of hundreds of thousands of pigment filled sacs to…

The nervous system likely evolved to control behavior. However, the earliest nerve nets were highly decentralized, raising questions about how such control was achieved. To explore this question, we study neural dynamics in Clytia hemisphaerica, a genetically accessible hydrozoan jellyfish. Despite lacking a…

Octopuses are an emerging model organism in neurobiology due to their unique nervous system and capacity for intelligence. However, due to this novelty, nothing is currently known about many of their receptors, including those involved in neuromodulation. Given the historical significance of dopamine action in the…

While sleeping, many vertebrate groups alternate between at least two sleep stages: rapid eye movement (REM) and slow wave sleep (SWS), in part characterized by wake-like and synchronous brain activity respectively. Sleep stage alternation has been implicated in learning and memory function experimentally1, and has…
