    High-resolution quantitative and functional MRI indicate lower myelination of thin and thick stripes in human secondary visual cortex

    Daniel Haenelt, Robert Trampel ... Nikolaus Weiskopf
    In vivo quantitative magnetic resonance imaging at ultra-high magnetic field reveals systematic differences of relaxation parameters (R1) within the human secondary visual cortex at the level of the thin-thick-pale stripes system, which points toward higher cortical myelination of pale stripes.

    Activity disruption causes degeneration of entorhinal neurons in a mouse model of Alzheimer’s circuit dysfunction

    Rong Zhao, Stacy D Grunke ... Joanna L Jankowsky
    Chemogenetic silencing reveals that entorhinal neurons require ongoing activity for survival, suggesting that their normal physiology may render them vulnerable to pathologies that impair transmission.

    The injured sciatic nerve atlas (iSNAT), insights into the cellular and molecular basis of neural tissue degeneration and regeneration

    Xiao-Feng Zhao, Lucas D Huffman ... Roman J Giger
    Single-cell analysis of injured mouse sciatic nerves reveals rapid reprogramming of macrophages toward a glycolytic, proinflammatory phenotype during the early repair process.

    The NAD+ precursor NMN activates dSarm to trigger axon degeneration in Drosophila

    Arnau Llobet Rosell, Maria Paglione ... Lukas Jakob Neukomm
    Levels of the metabolite NMN, the precursor of NAD+, determine whether dSarm-mediated axon death signaling is activated and injury-induced axon degeneration executed in the fruit fly Drosophila.

    Cold protection allows local cryotherapy in a clinical-relevant model of traumatic optic neuropathy

    Yikui Zhang, Mengyun Li ... Wencan Wu
    Local deep hypothermia combined with hibernation-mimicking cold protection is neuroprotective in a translatable large animal model of traumatic optic neuropathy.

    Activation of the CaMKII-Sarm1-ASK1-p38 MAP kinase pathway protects against axon degeneration caused by loss of mitochondria

    Chen Ding, Youjun Wu ... Marc Hammarlund
    Axon degeneration due to loss of mitochondria is suppressed by CaMKII activity and MAP kinase signaling.

    Progressive axonopathy when oligodendrocytes lack the myelin protein CMTM5

    Tobias J Buscham, Maria A Eichel-Vogel ... Hauke B Werner
    When oligodendrocytes lack expression of the low-abundant myelin protein CMTM5, central nervous system axons are myelinated normally but subsequently degenerate involving a Wallerian-like pathomechanism.

    Impact of long- and short-range fibre depletion on the cognitive deficits of fronto-temporal dementia

    Melissa Savard, Tharick A Pascoal ... Pedro Rosa-Neto
    While semantic symptoms in fronto-temporal dementia patients were mainly dependent on short-range white-matter fibre disruption, long-range white-matter fibres damage was the major contributor to executive dysfunction, highlighting the importance of controlling for risk factors associated with deep white-matter disease.

    Neurotoxin-mediated potent activation of the axon degeneration regulator SARM1

    Andrea Loreto, Carlo Angeletti ... Michael P Coleman
    The identification of the mechanism of action of vacor, an environmental neurotoxin which causes neurodegeneration by activating the pro-degenerative enzyme SARM1, raises important questions on SARM1 as a mediator of environmental neurotoxicity and has implications for drug discovery.

    Partial connectomes of labeled dopaminergic circuits reveal non-synaptic communication and axonal remodeling after exposure to cocaine

    Gregg Wildenberg, Anastasia Sorokina ... Bobby Kasthuri
    3D serial electron microscopy reveals that individual dopamine axons in the nucleus accumbens contain different varicosity types based on their vesicle contents, rarely make synapses, and undergo major structural plasticity in response to cocaine.
