Studies of the house mouse Mus musculus have provided important insights into mammalian biology, and efforts to study wild house mice and to create new inbred strains from wild populations have the potential to increase its usefulness as a model system.

The three main types of inhibitory neurons in mouse primary visual cortex respond differently to locomotion in darkness and during visual stimulation, revealing context-dependent responses to changes in behavioral state.

High-resolution, large-scale immunohistochemical mouse brain images showing global views of different brain regions, as well as cellular and subcellular details, identified distinct localization of PKA RIβ and RIIβ regulatory subunits that reveal functional differences.

Post-implantation epiblast maturation and patterning of anterior-posterior axis in mouse embryonic development are mediated by pluripotency transcription factor Zfp281 through transcriptional and epigenetic control of Nodal signaling.

Single embryo RNA-seq combined with mouse genetics provides a comprehensive view on the roles of Rlim and Xist for the regulation of X-linked gene expression during early mouse embryogenesis.

A panel of seven new mouse strains with chromosomal duplications is used to identify a minimal genetic region required in three copies to cause congenital heart defects typical of human Down syndrome.

A realistic model of the connections between local populations of neurons in the adult mouse brain can be constructed based on just two biologically plausible rules.

Acute one-hour treatment of Pik3ca mutant mice with a novel anti-epilepsy drug suppresses seizures despite continued developmental brain dysmorphology, promising a new therapeutic strategy for patients with intractable pediatric epilepsy.

An innovative, fully computerized approach for measuring spontaneous social behavior in mice closely follows murine ethology, eliminates crucial sources of data irreproducibility and enables fast, inexpensive assessment of sociability in group-housed subjects.

Long intergenic noncoding RNA molecules (lincRNAs) are shown to have critical roles in mammalian development and physiology in vivo.
