Virtual reality experiments show that motorists slow down when driving in fog, but they speed up when visibility is reduced equally at all distances.

A genome-organizing protein that is present only in the olfactory system of mice has been found to orchestrate changes in the relative numbers of different odor-sensing neurons on the basis of how active these neurons are.

The first survey of the complete morphologies of nerve endings in the skin of mice has revealed enormous structural diversity.

Novel imaging experiments suggest that fruit flies modify their neural circuitry for walking at slow, medium and fast speeds, and that proprioception is not essential for coordinated walking.

The ability of epithelial cells to distinguish between domains on opposing cell surfaces within a tissue, a property known as planar cell polarity, relies on proteins and protein complexes directing the traffic of signaling proteins to specific locations on the cell surface membrane.

The HITS-CLIP sequencing method is used to demonstrate that cryptic exons can detect messenger RNA that contains nonsense mutations, and then cause this RNA to decay, which shows that these exons are involved in maintaining the electrical balance of neurons and, possibly, preventing epilepsy.

Changing the order in which presynaptic and postsynaptic cells are repeatedly activated can change what a mammalian visual cortex neuron communicates to downstream neurons.

The nematode worm C. elegans consumes familiar bacterial species more rapidly than it does novel ones, and this preference for familiarity is mediated by a pair of serotonergic neurons.

Islands of non-methylated DNA are shown to perform a similar epigenetic role in many different vertebrate species.

The Notch signaling pathway has a central role in the development of the nervous system, and also in the establishment of networks of connections in the adult brain
