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.
Spontaneous growth arrest of transformed melanocytes (resulting in benign “moles”) does not result from cell-autonomous oncogene-induced senescence, but can be explained by collective mechanisms used in normal tissue size control.
Propagation, speed and shapes of genetic waves of expression during development can be modeled by a simple interplay between two transcriptional modules (dynamic/static), which explains robustness and precision of patterning.
Parabrachial neurons expressing CGRP relay affective components of ascending pain information via distinct thalamic and amygdalar pathways, which together contribute to complementary aspects of adaptive threat responses.
Instant performance recovery is possible following general anesthesia-induced unconsciousness using antagonist, and the brain dynamics return abruptly to the awake state without intermediate recovery states.
Administration of dopamine and opioid receptor antagonists resulted in reduced reward anticipation (effort and increased negative facial reactions), but only administration of opioid antagonists resulted in reduced liking (facial reactions).
