Clytia jellyfish regenerate body shape and organs through a mechanically driven process that coordinates tissue remodeling, localized proliferation, and precursor migration and promotes Wnt signaling at a muscle-based landmark.
Ketamine, an NMDA receptor antagonist and experimental model for schizophrenia, produces decision-making deficits in monkeys, which are predicted by a lowering of cortical excitation-inhibition balance in a spiking circuit model.
Whisker barrels provide clues about neocortical development, as computer modelling shows that barrels can self-organize, based on competition between adjacent thalamocortical axons, suggesting that genetic instruction plays a secondary role.
Characterization of a novel population of enteric nervous system glial cells in zebrafish reveals their proliferative and neurogenic properties under homeostatic conditions in adults, properties difficult to model in mammals.
This review serves as a gateway to experimental, conceptual, and quantitative themes of cytoplasmic incompatibility (CI) and outlines significant gaps in the understanding of CI's mechanism that are ripe for investigation.
LOV2GIVe allows to activate Gi proteins non-invasively with innocuous blue light based on a design principle unrelated to light-activated GPCRs (metazoan opsins), thereby expanding the range of potential experimental applications.
