    Evolution of neuronal anatomy and circuitry in two highly divergent nematode species

    Ray L Hong, Metta Riebesell ... Ralf J Sommer
    The substrate for evolutionary divergence does not lie in changes in neuronal cell number or targeting, but rather in sensory perception and synaptic partner choice within invariant, prepatterned neuronal processes.

    Genetic mechanisms control the linear scaling between related cortical primary and higher order sensory areas

    Andreas Zembrzycki, Adam M Stocker ... Dennis DM O'Leary
    Primary and higher order visual area dimensions in the neocortex are determined by the same genetic mechanisms during development which in turn also control the proportionate scaling between them.

    Cellular cartography of the organ of Corti based on optical tissue clearing and machine learning

    Shinji Urata, Tadatsune Iida ... Shigeo Okabe
    A method of generating comprehensive maps of cochlear cells was created and enabled researchers to study characteristics of cellular damage in aged and noise-exposed inner ear.
    1. Neuroscience

    The wiring diagram of a glomerular olfactory system

    Matthew E Berck, Avinash Khandelwal ... Albert Cardona
    The complete neural circuit map of a tractable olfactory system will support studies towards bridging the gap between circuits and behavior.

    Detection of transient synchrony across oscillating receptors by the central electrosensory system of mormyrid fish

    Alejandro Vélez, Bruce A Carlson
    Building on previous work (Baker et al., 2015), further evidence is reported for a novel mechanism for sensory coding based on the detection of oscillatory synchrony among peripheral receptors.

    Interaction of human keratinocytes and nerve fiber terminals at the neuro-cutaneous unit

    Christoph Erbacher, Sebastian Britz ... Nurcan Üçeyler
    Sensory nerve fiber ending ensheathment and connexin 43 contacts by keratinocytes at the neuro-cutaneous unit can be visualized and quantified at super-resolution in human skin.

    Neuroanatomy of a hydrothermal vent shrimp provides insights into the evolution of crustacean integrative brain centers

    Julia Machon, Jakob Krieger ... Steffen Harzsch
    A neuroanatomical analysis of Rimicaris exoculata provides insights into these animal’s brain architecture to illustrate possible adaptations to the hydrothermal vent habitat with its extreme physicochemical conditions.

    Divergent sensory investment mirrors potential speciation via niche partitioning across Drosophila

    Ian W Keesey, Veit Grabe ... Bill S Hansson
    Phototaxis and courtship behavioral preferences reflect strong correlation with differences in olfactory and visual nervous system investment across five monophyletic Drosophila species, and could help explain their speciation events.
    1. Neuroscience

    Semiochemical responsive olfactory sensory neurons are sexually dimorphic and plastic

    Aashutosh Vihani, Xiaoyang Serene Hu ... Hiroaki Matsunami
    Semiochemicals activate a subpopulation of sexually dimorphic olfactory sensory neurons.

    Characterization of cephalic and non-cephalic sensory cell types provides insight into joint photo- and mechanoreceptor evolution

    Roger Revilla-i-Domingo, Vinoth Babu Veedin Rajan ... Kristin Tessmar-Raible
    Molecular, cellular and behavioral genetic approaches in Platynereis dumerilii indicate that r-Opsins can act as ancient, light-dependent modulators of mechanosensation, and suggest that light-independent mechanosensory roles of r-Opsins evolved secondarily.
