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.
The direction-selective circuit in the retina adjusts the contributions of excitatory and inhibitory mechanisms under different stimulus conditions to generate context-dependent neural representations of visual features.
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.
Theory explains how transport of gene expression vortices by cell advection may cause intermingled defective and normal segments along the body axis during resynchronization experiments in the zebrafish segmentation clock.
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.
