The finding that fly maggots, equipped with only 10,000 neurons, process reinforcement not only by value but also by specific quality reveals a basic operating principle of brains and challenges current models of memory organization.
A very large number of place-field maps can be robustly learned by association of external cues with the grid-driven response, however plasticity in the grid-cell inputs renders the place-cell responses volatile.
Mitophagy regulates mitochondrial quality and mediates extensive mitochondrial degradation in (patho-)physiological settings and is one of the key components of hypoxic preconditioning which protects the heart from ischemia/reperfusion injury.
Fundamental details of the rate and molecular spectrum of transcript errors were revealed in four bacterial species, providing novel insights into transcriptional fidelity and RNA quality-control in prokaryotes.
Analysis and modeling of group behavior of adult zebrafish shows that a specialized social interaction mechanism increases foraging efficiency and equality within groups, under a variety of environmental conditions.
