Neuronal ELAV-like (nELAVL) proteins are associated with non-coding Y RNAs in stressed neurons and in the brains of Alzheimer's disease patients, suggesting a new means of regulatory protein sequestration and mRNA target regulation.
The use of stone tools by macaques in Thailand has reduced the size and population density of coastal shellfish; previously it was thought that tool-assisted overharvesting effects resulted uniquely from human activity.
A multi-phase wrinkling model accounts for the radial and circumferential tension and differential expansion between a uniformly proliferating outer fluid-like layer and an incompressible core that together drive cerebellar folding.
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.
Brain imaging and behavioral analysis reveal two opposing states of hunger, represented by anti-correlated lateral and caudal hypothalamic dynamics that are important for the homeostatic control of feeding in zebrafish.
Empirical evaluations demonstrate the low probability of finding and replicating significant associations between psychological tests and brain structure in healthy adults, highlighting the importance out-of-sample replication of exploratory findings.
The brain obtains and preserves a consistent temporal alignment of multisensory and motor information flowing along staggered streams by maintaining an invariant estimate across modalities of the energy exchanged with the environment at discrete events.
