    Sox10-dependent neural crest origin of olfactory microvillous neurons in zebrafish

    Ankur Saxena et al.
    Sensory neurons in the olfactory system develop from two different regions of the ectoderm, the olfactory placode and the cranial neural crest, whereas sensory neurons within the eye and ear develop from just one region.

    Acute stress enhances adult rat hippocampal neurogenesis and activation of newborn neurons via secreted astrocytic FGF2

    Elizabeth D Kirby et al.
    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.

    Cavin-3 dictates the balance between ERK and Akt signaling

    Victor J Hernandez et al.
    Cavin-3 is a tumor suppressor protein that inhibits Akt signaling, suppresses Warburg metabolism, promotes apoptosis, and protects against cachexia.

    A network of heterochronic genes including Imp1 regulates temporal changes in stem cell properties

    Jinsuke Nishino et al.
    A set of genes that are turned on only within time-limited windows—including genes encoding RNA binding molecules, let-7 microRNAs and IMP1—control developmental switches in stem cell properties between fetal development and adulthood.

    Synchronous and asynchronous modes of synaptic transmission utilize different calcium sources

    Hua Wen et al.
    The delayed-onset of asynchronous transmitter release seen in neurons that fire repeatedly is triggered by a different source of calcium from that which triggers synchronous transmitter release.

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

    Qin Li et al.
    PTBP2 ensures that adult protein variants are expressed only in mature neurons through regulation of alternative splicing during early neuronal development.

    The structure and organization of lanceolate mechanosensory complexes at mouse hair follicles

    Lishi Li, David D Ginty
    Close examination of lanceolate mechanosensory complexes has revealed clues about the ways that sensory nerves detect the movement of hairs and shown than terminal Schwann cells are needed to maintain and regenerate these intricate structures.

    ErbB expressing Schwann cells control lateral line progenitor cells via non-cell-autonomous regulation of Wnt/β-catenin

    Mark E Lush, Tatjana Piotrowski
    Schwann cell induced quiescence of mechanosensory progenitor cells is mediated by inhibition of Wnt/β-catenin signaling.

    A high-resolution morphological and ultrastructural map of anterior sensory cilia and glia in Caenorhabditis elegans

    David B Doroquez et al.
    The three-dimensional structures of 50 sensory cilia present in the head of the adult C. elegans hermaphrodite have been reconstructed to provide a foundation for investigations into the mechanisms by which the diversity of cilia structures is generated and how this structural diversity is related to specific sensory neuron functions.

    A frontal cortex event-related potential driven by the basal forebrain

    David P Nguyen, Shih-Chieh Lin
    Contrary to the common belief that cognitive event-related potentials are generated by local activity within the cerebral cortex, it is shown that some of these potentials are modulated by subcortical inputs.
