    scMultiome analysis identifies embryonic hindbrain progenitors with mixed rhombomere identities

    Yong-Il Kim, Rebecca O'Rourke, Charles G Sagerström
    Combined single nucleus RNAseq and ATACseq enabled the first molecular resolution of all hindbrain rhombomeres, the derivation of a unique gene regulatory network for each rhombomere, and the identification of gene expression changes as rhombomeres form from early progenitor pools.

    A dynamic and expandable digital 3D-atlas maker for monitoring the temporal changes in tissue growth during hindbrain morphogenesis

    Matthias Blanc, Giovanni Dalmasso ... Cristina Pujades
    The digital 3D-atlas maker will help ascribing neuronal birthdate and neuronal differentiation times upon gene disruption in zebrafish avatars for human diseases, and will allow the integration of the information generated in other laboratories.

    A fully automated high-throughput workflow for 3D-based chemical screening in human midbrain organoids

    Henrik Renner, Martha Grabos ... Jan M Bruder
    Automated liquid handling, whole mount staining, and clearing allow unbiased 3D quantitation of cell markers in human neural organoids with diameters of up to 1 mm at the single-cell level.

    Transcriptomic atlas of midbrain dopamine neurons uncovers differential vulnerability in a Parkinsonism lesion model

    Behzad Yaghmaeian Salmani, Laura Lahti ... Thomas Perlmann
    Single nuclei RNA sequencing unmasks 16 variants of midbrain dopamine neurons within a continuum of their gene expression landscape and resolves their differential vulnerability.

    Dissociation of task engagement and arousal effects in auditory cortex and midbrain

    Daniela Saderi, Zachary P Schwartz ... Stephen V David
    Data collected from two important auditory brain areas distinguish effects of generalized arousal and specific task engagement on neural sensory coding.

    β2-subunit alternative splicing stabilizes Cav2.3 Ca2+ channel activity during continuous midbrain dopamine neuron-like activity

    Anita Siller, Nadja T Hofer ... Jörg Striessnig
    Regulation of Cav2.3 Ca2+ channels by membrane-bound β2 subunit splice variants permits long-lasting channel activity even during prolonged and continuous activity in dopamine neurons, with implications for Parkinson's disease pathophysiology.

    Noise modulation in retinoic acid signaling sharpens segmental boundaries of gene expression in the embryonic zebrafish hindbrain

    Julian Sosnik, Likun Zheng ... Thomas F Schilling
    Direct measurements of retinoic acid using fluorescence lifetime imaging reveal a new role for cellular retinoic acid binding proteins in noise attenuation that is critical to sharpen hindbrain rhombomere boundaries.
    1. Neuroscience

    Sensory prediction errors in the human midbrain signal identity violations independent of perceptual distance

    Javier A Suarez, James D Howard ... Thorsten Kahnt
    Activity in the midbrain responds to unexpected changes in outcome identity (i.e. sensory prediction error) but does not scale with perceptual distance between expected and receipt reward.
    1. Neuroscience

    Midbrain dopaminergic inputs gate amygdala intercalated cell clusters by distinct and cooperative mechanisms in male mice

    Ayla Aksoy-Aksel, Andrea Gall ... Ingrid Ehrlich
    Dopaminergic input shapes activity of specialized amygdala inhibitory cell clusters by ionotropic and metabotropic mechanisms that may enable their selection during distinct fear-related behavioral states.
    1. Neuroscience

    Midbrain dopamine neurons sustain inhibitory transmission using plasma membrane uptake of GABA, not synthesis

    Nicolas X Tritsch, Won-Jong Oh ... Bernardo L Sabatini
    The molecular mechanisms by which midbrain dopamine neurons acquire the inhibitory neurotransmitter GABA for synaptic release are revealed.
