    NOVA-dependent regulation of cryptic NMD exons controls synaptic protein levels after seizure

    Taesun Eom, Chaolin Zhang ... Robert B Darnell
    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.

    Skill learning strengthens cortical representations of motor sequences

    Tobias Wiestler, Jörn Diedrichsen
    Detailed analysis of fMRI data shows that sequences of movements are associated with individual patterns of neural activity that become more distinct with training.

    Deprivation-related and use-dependent plasticity go hand in hand

    Tamar R Makin, Alona O Cramer ... Heidi Johansen-Berg
    In individuals with a missing hand, the area of the brain that would otherwise control that hand is recruited by either the remaining hand or the residual limb, depending on the usage preference of the individual.

    Development of schemas revealed by prior experience and NMDA receptor knock-out

    George Dragoi, Susumu Tonegawa
    Novel spatial representations by hippocampal cellular assemblies develop on the framework of preconfigured hippocampal networks whose homeostatic synaptic reorganization is accelerated by prior experience and CA3 NMDAR-dependent plasticity.

    Deregulated FGF and homeotic gene expression underlies cerebellar vermis hypoplasia in CHARGE syndrome

    Tian Yu, Linda C Meiners ... M Albert Basson
    Mutations in CHD7, which cause CHARGE syndrome, cause a reduction in FGF8 signalling and subsequent abnormalities in the cerebellar vermis in both mice and humans.

    The splicing regulator PTBP2 controls a program of embryonic splicing required for neuronal maturation

    Qin Li, Sika Zheng ... Douglas L Black
    PTBP2 ensures that adult protein variants are expressed only in mature neurons through regulation of alternative splicing during early neuronal development.

    Monosynaptic premotor circuit tracing reveals neural substrates for oro-motor coordination

    Edward Stanek IV, Steven Cheng ... Fan Wang
    Retrograde tracing of the neural circuits that control movement of the jaw and tongue reveals how shared premotor neurons help to ensure coordinated muscle activity.

    Prospective identification of functionally distinct stem cells and neurosphere-initiating cells in adult mouse forebrain

    John K Mich, Robert AJ Signer ... Sean J Morrison
    Flow cytometric isolation and fate mapping shows that neurosphere-initiating cells are highly mitotically active and persist only transiently in vivo, and are distinct from quiescent, long-lived neural stem cells.
    1. Neuroscience

    Cerebellar modules operate at different frequencies

    Haibo Zhou, Zhanmin Lin ... Martijn Schonewille
    Zebrin-positive cerebellar Purkinje cells fire at lower frequencies than zebrin-negative cells, indicating that cerebellar circuits are not physiologically homogeneous.
