Replay of recently experienced trajectories during a decision task is coupled with more effective adaptation to change, whereas replay during rest is associated with limited decision making flexibility.
Stunning new scan data of an enigmatic fish from the Early Devonian of Australia, Ligulalepis, is identified as a stem osteichthyan, specifically, as the sister taxon to the 'psarolepids' plus crown osteichthyans.
In a minimalistic, generic model of competitive communities in which evolution is constrained by life-history trade-offs, stable biodiversity emerges with species adapted to different functional niches.
The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.
Brain-derived neurotrophic factor (BDNF)/TrkB.T1 signaling contributes to astrocyte morphological maturation, with implications for neuronal synaptogenesis and function and astrocyte functional maturation.
Two evolutionary distant insect species share a common head direction circuit with subtle differences in neuronal morphologies that result in distinct circuit dynamics adapted to each species’ ecology.
