    Tandem hnRNP A1 RNA recognition motifs act in concert to repress the splicing of survival motor neuron exon 7

    Irene Beusch, Pierre Barraud ... Frédéric Hai-Trieu Allain
    The structural model of hnRNP A1 shows that it can bind with both RRMs to RNA, which is shown to be relevant for the SMN2 exon 7 splicing mechanism in vivo.

    Motor cortex signals for each arm are mixed across hemispheres and neurons yet partitioned within the population response

    Katherine Cora Ames, Mark M Churchland
    Neurons in motor cortex contain information about each arm, but these signals are separated into different dimensions, allowing separate control of each arm.

    Chemogenetic inhibition of the medial prefrontal cortex reverses the effects of REM sleep loss on sucrose consumption

    Kristopher McEown, Yohko Takata ... Michael Lazarus
    Loss of REM sleep increases sucrose and fat consumption in mice; and inhibiting the prefrontal cortex reverses the increased consumption of sucrose, but not fat, following REM sleep loss.

    Targeted memory reactivation in human REM sleep elicits detectable reactivation

    Mahmoud EA Abdellahi, Anne CM Koopman ... Penelope A Lewis
    Sound cues that were associated with memories during wake elicit memory reactivations when replayed to human participants during rapid eye movement sleep, those memory reactivations are identifiable by machine learning models that directly relate electroencephalography patterns of wake and sleep.

    The human leukemia virus HTLV-1 alters the structure and transcription of host chromatin in cis

    Anat Melamed, Hiroko Yaguchi ... Charles RM Bangham
    The human leukemia virus HTLV-1 causes abnormal chromatin looping in tens of thousands of infected T cell clones in each host, and abnormal host transcription both flanking the integrated provirus and at distant loci in cis.

    Postural control of arm and fingers through integration of movement commands

    Scott T Albert, Alkis M Hadjiosif ... Reza Shadmehr
    After a movement, the final posture of the arm is stabilized by a subcortical structure that mathematically integrates movement commands over time.

    Early life experience sets hard limits on motor learning as evidenced from artificial arm use

    Roni O Maimon-Mor, Hunter R Schone ... Tamar R Makin
    Biological- or artificial-arm experience during early development has a significant effect on artificial-arm motor control in adulthood, providing evidence for limited sensorimotor plasticity beyond childhood.

    Area 2 of primary somatosensory cortex encodes kinematics of the whole arm

    Raeed H Chowdhury, Joshua I Glaser, Lee E Miller
    Area 2 of somatosensory cortex represents kinematic details of the entire arm during movement, but this mapping from limb state to neural activity differs for reaching and passive limb displacement.

    The RAM signaling pathway links morphology, thermotolerance, and CO2 tolerance in the global fungal pathogen Cryptococcus neoformans

    Benjamin J Chadwick, Tuyetnhu Pham ... Xiaorong Lin
    In the fungal pathogen Cryptococcus neoformans, the RAM pathway, potentially through post-transcriptional regulation, plays an essential role in adaptation to host temperature and CO2.

    The energetic basis for smooth human arm movements

    Jeremy D Wong, Tyler Cluff, Arthur D Kuo
    An energetic cost related to force rate is quantified in human arm movements, and minimizing this cost predicts smoothness without minimizing variance, unifies motor-planning of smoothness and movement duration, and may help resolve motor redundancies.
