    miR-125-chinmo pathway regulates dietary restriction-dependent enhancement of lifespan in Drosophila

    Manish Pandey, Sakshi Bansal ... Geetanjali Chawla
    miR-125 functions as a potential dietary restriction mimetic by promoting longevity through regulation of fat metabolism.

    Neural signatures of auditory hypersensitivity following acoustic trauma

    Matthew McGill, Ariel E Hight ... Daniel B Polley
    Chronic two-photon calcium imaging, optogenetics, and operant behavioral approaches were leveraged to show that hyperactivity, hyperresponsivity, and hypersynchronization in auditory cortex neural ensembles can account for auditory hypersensitivity following acoustic trauma.

    Infant brain regional cerebral blood flow increases supporting emergence of the default-mode network

    Qinlin Yu, Minhui Ouyang ... Hao Huang
    Unprecedented 4D spatiotemporal infant regional cerebral blood flow framework and region-specific physiology–function coupling across infancy were elucidated, highlighting strong physiology–function coupling specifically at the default-mode network to meet extraneuronal metabolic demand for network emergence.

    Tenectin recruits integrin to stabilize bouton architecture and regulate vesicle release at the Drosophila neuromuscular junction

    Qi Wang, Tae Hee Han ... Mihaela Serpe
    Characterization of Tnc as a selective integrin ligand at the Drosophila NMJ allows for unprecedented insights into our understanding of extracellular matrix/integrin interactions at synaptic locations and reveals novel, distinct presynaptic and postsynaptic integrin functions.

    Retinal input integration in excitatory and inhibitory neurons in the mouse superior colliculus in vivo

    Carolin Gehr, Jeremie Sibille, Jens Kremkow
    Excitatory and inhibitory neurons in the mouse superior colliculus receive comparably strong inputs from retinal ganglion cells, in contrast to the thalamocortical system.

    Non-linear developmental trajectory of electrical phenotype in rat substantia nigra pars compacta dopaminergic neurons

    Martial A Dufour, Adele Woodhouse ... Jean-Marc Goaillard
    The development of the electrical phenotype of neurons can be precisely quantified and dissected using a combination of multi-variate statistical analyses and a systematic electrophysiological characterization of electrical properties.

    Nociceptive interneurons control modular motor pathways to promote escape behavior in Drosophila

    Anita Burgos, Ken Honjo ... Wesley B Grueber
    A class of interneuron is identified that promotes escape behavior downstream of nociceptor inputs via connections to nociceptive integrator and premotor networks.

    Dendritic nonlinearities are tuned for efficient spike-based computations in cortical circuits

    Balázs B Ujfalussy, Judit K Makara ... Máté Lengyel
    Dendrites combine the inputs that they receive from other neurons using calculations that have been optimized for those particular input patterns.

    Microsecond interaural time difference discrimination restored by cochlear implants after neonatal deafness

    Nicole Rosskothen-Kuhl, Alexa N Buck ... Jan WH Schnupp
    Early deaf human CI users are often insensitive to sub-millisecond interaural time differences (ITDs); however, with synchronized CIs, early deafened rats learned to lateralize small ITDs near 50 µs.

    Local projections of layer Vb-to-Va are more prominent in lateral than in medial entorhinal cortex

    Shinya Ohara, Stefan Blankvoort ... Menno P Witter
    The connection from layer Vb-to-Va neurons, a key component of the canonical hippocampal-cortical output circuit, which is allegedly crucial for memory consolidation, is relatively stronger in lateral entorhinal cortex compared with the medial entorhinal cortex, thus suggesting different operating principles.
