Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences (NAS) - an authoritative source of high-impact, original research that broadly spans...

Noradrenergic circuits support and balance aggressive behavioural states in predatory nematodes, distinguish predatory from non-predatory nematode species and are associated with the evolution of comp...

Nature - Using two-photon microscopy with a panoramic virtual reality setup, how head direction cells in larval zebrafish integrate visual landmarks and optic flow to track orientation is revealed.

In the fly central complex, PFNa neurons switch from firing classical sodium spikes when depolarized to firing non-canonical T-type calcium spikes when hyperpolarized. This bidirectional spiking allow...

The thermosensory system across insects and mammals has shared principles of neuronal wiring and encoding. In this Review, Carta, Vestergaard and Poulet discuss how the nervous systems of insects and ...

Psilocybin reshapes brain networks through activity-dependent plasticity, including a weakening of recurrent cortical loops that could underlie its therapeutic effects.

Understanding how the cellular and molecular composition of neural circuits evolves to generate species-specific behaviors remains a major challeng...

Caterpillars (larval Lepidoptera) are one of the most ecologically and evolutionarily significant taxa on Earth. As both feeders and food, they shape the dynamics of enumerate ecosystems on land. Key ...

The mechanism enables each olfactory neuron in the ant to express exactly one out of hundreds of olfactory receptors.

Figuring out how the brain uses information from visual neurons may require new tools. I asked nine experts to weigh in.

ALT: a black and white dog is sitting on a couch with its tongue sticking out .

Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Soc...

Sexual selection acts on heritable differences within species, driving the parallel diversification of signal production in one sex and behavioral responses in the other. This coevolution implies that...

To identify fundamental neuroscientific principles that generalize across species, neuroscientists must frame their research through an evolutionary lens.

Hartman et al. describe a cell type in the Drosophila visual system that is activated during head grooming through visual and non-visual signals arising from foreleg movements. These neurons inhibit a...

Kim et al. investigate how the Drosophila olfactory system dynamically transforms odor information. They discover that distinct synaptic dynamics from individual projection neurons underlie different ...

Abstract. Colonization of new habitats is typically followed by divergent selection acting on traits that are immediately important for fitness. For exampl

Birds have an excellent ability to learn to discriminate harmless insects from those that they mimic on the basis of subtle differences in appearance.

Background Chelicerate evolution is contentiously debated, with recent studies challenging traditional phylogenetic hypotheses and scenarios of major evolutionary events, like terrestrialization. Sea ...
