The BB model explains spatial cognition in terms of interactions between specific neuronal populations, providing a common computational framework for the human neuropsychological and in vivo animal electrophysiological literatures.
During meiosis, budding yeast use a checkpoint involving the protein Mec1 to prevent the formation of double-strand breaks in DNA that has not completed replication.
Selection for undifferentiated multicellularity emerges in an evolutionary cell-based model because a collective of cells performs chemotaxis better than single cells in a noisy environment.
Experimental evolution shows that when selection acts on two traits constrained by a trade-off, the direction of phenotypic evolution depends on the environment.
Despite the virus' error prone polymerase, influenza virus antigenic evolution is rare, even in previously immune hosts, virus replication occurs before producing new antibodies.
Dynein-dependent microtubule-cortex interactions – "side-on" versus "end-on" pulling – are regulated by cortical ER and mediated by distinct pools of cortical anchor that are differentially localized along the cell periphery.
FRET biosensor-based measurement of cAMP signaling and single-channel recording reveal that β-blockers trigger local activation of adrenergic receptors and calcium channels in primary neurons.
As rats learn to traverse back and forth on a track, visual cortical neurons fire at specific locations and functionally interact with those hippocampal place cells representing the same locations.
