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.
Using different sets of input sequences to evolutionary reconstruction algorithms results in the exploration of many possible models, the intergration over which produces significantly more accurate models.
Grid cells lose their hexagonality during hippocampal inactivation, but maintain temporal and spatial synchrony between pairs of cells, implying that hippocampus does not determine phase relations between grid cells.
The histone modification H3K9me2 marks peripheral heterochromatin and ensures positional information is safeguarded through cell division such that individual lamina-associated domains are re-established at the nuclear periphery in daughter nuclei.
Probability of upcoming actions modulates subclasses of neurons in frontoparietal motor-planning areas in a complementary fashion and frontal-lobe processing takes the leading role when primates commit to a decision.
