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 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 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

The Notch signaling pathway has a central role in the formation of the circuit that controls egg-laying in the nematode worm C. elegans.

By using different groups of cells to represent distinct environments and events, the dentate gyrus of the hippocampus helps to keep memories of similar events separate.

Exposing rats to acute stress increased the generation of new neurons in a subregion of the hippocampus, and improved the animals' performance in a memory task two weeks later.

Experiments on synthetic models of synaptic vesicles have shed new light on the role of the protein α-synuclein in the central nervous system.
