Dorsomedial and dorsolateral striatal neural activity differ during early learning of action sequences but do not change with performance improvement across sessions, and become similar after extended training.
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.
Investigation of global gene expression profiles during formation of the Myxococcus xanthus specialized biofilm reveals a genetic regulatory network that coordinates cell motility, differentiation, and secondary metabolite production.
Neural populations may depend on balanced recurrent connectivity to produce an efficient stimulus representation while also maintaining an accurate stimulus encoding despite the variability introduced by adapting neural responses.
The substrate for evolutionary divergence does not lie in changes in neuronal cell number or targeting, but rather in sensory perception and synaptic partner choice within invariant, prepatterned neuronal processes.
