The dorsal fan-shaped body and sleep

The dorsal fan-shaped body and sleep

The role of the dorsal fan-shaped body in sleep regulation in Drosophila is contested. Joseph Jones, Brandon Holder, Stephane Dissel and colleagues show that cholinergic neurons in the dorsal fan-shaped body play a major role in sleep modulation in this neurochemically heterogeneous sleep-regulating center in the fly brain.

Propagating conceptual information in the brain

How does sensory information activate and construct representations in the human brain? David Acunzo, Damiano Grignolio and Clayton Hickey show that a neuronal network that includes the prefrontal and posterior parietal cortex and the anterior insula has a key role in the translation of perceptual information to concepts, semantics and action plans.

Navigation strategy learning in worms

How do worms navigate based on learned experience? Kevin Chen, Anuj Sharma, Jonathan Pillow and Andrew Leifer reveal the flexible behavioral strategies and distributed neural computations that underlie learning-dependent odor navigation in Caenorhabditis elegans.

Enhanced memory and sleep

Sleep is known to support memory; however, Sheng Huang, Chengji Piao, Stephan Sigrist and colleagues identify an instance where memory hyperfunction may actually provoke sleep deficits. They find that the short-sleep Drosophila mutant, insomniac, has enhanced memory and that PKA signaling balances sleep and memory in these flies.

Outomes of past conservation efforts

Understanding the consequences of past conservation efforts is essential to inform how we maintain and restore species. An analysis of IUCN Red List data on 67,217 animal species, by Ashley Simkins, Silviu Petrovan and co-workers, reveals that a range of different conservation actions have successfully conserved species that are at greatest risk of extinction, but have rarely resulted in full recovery.

Short Reports

Double-bladed bacterial toxins

The secretion mechanisms of many type VI secretion system (T6SS) effectors in Gram-negative bacteria remain unclear. Chaya Mushka Fridman, Eran Bosis, Dor Salomon and colleagues identify a new class of T6SS effectors which can harbor either one or two toxic domains and use WHIX as a secretion motif.

Is beauty beyond the eye of the butterfly?

The diversity of bright colors observed across the animal world are often used during mate choice. Richard Merrill explores a new study in PLOS Biology which reveals genetic and neural mechanisms contributing to the evolution of visual mating decisions in Heliconius butterflies.
