Intracranial recordings of human brain activity during awakening from general anesthesia exhibit a brief brain state not seen during loss of consciousness, in which stimuli elicit large electrophysiological responses that resemble those seen in sleep.
Inspiratory rhythmogenesis is mediated by an emergent mechanism independent of bursts associated with motor output and is modulated by opioids, pointing to strategies for ameliorating opioid-induced respiratory depression.
In the context of an organism's ecology, physiology, and macroevolutionary history, inheritance and gene loss can yield emergent patterns of trait variability that give the appearance of gene acquisition.
Emergence of hematopoietic stem cells from an aortic component is a unique phenomenon of cell extrusion, with no equivalent in cell biology, and which is adapted to environmental constraints exerted by endothelial cells and hemodynamics forces.
LKB1 instructs the timing and location of synapse layer emergence in the outer retina by coordinating the regulation of pre- and postsynaptic neuron maturation and transport of synapse-associated proteins.
