    Complex spike synchrony dependent modulation of rat deep cerebellar nuclear activity

    Tianyu Tang, Timothy A Blenkinsop, Eric J Lang
    The importance of synchronous Purkinje cell complex spikes for controlling cerebellar output was investigated by simultaneously recording from cerebellar nuclear cells and arrays of Purkinje cells that synapse onto them.

    Cerebellar and vestibular nuclear synapses in the inferior olive have distinct release kinetics and neurotransmitters

    Josef Turecek, Wade G Regehr
    Inhibition from the cerebellar nuclei to the inferior olive is exclusively asynchronous and GABAergic, whereas the vestibular nuclei provide rapid synchronous inhibition mediated by mixed GABA and glycinergic synapses.

    Purkinje cell misfiring generates high-amplitude action tremors that are corrected by cerebellar deep brain stimulation

    Amanda M Brown, Joshua J White ... Roy V Sillitoe
    Genetic, pharmacologic, and optogenetic manipulations demonstrate that Purkinje cells can trigger and propagate the signals for tremor.

    Brain atlas for glycoprotein hormone receptors at single-transcript level

    Vitaly Ryu, Anisa Gumerova ... Mone Zaidi
    The most comprehensive neuroanatomical atlas on the expression of three glycoprotein hormone receptors, namely, TSHRs, LHCGRs, and FSHRs, was mapped using RNAscope, a technology that allows the detection of mRNA at single-transcript level.

    VTA-projecting cerebellar neurons mediate stress-dependent depression-like behaviors

    Soo Ji Baek, Jin Sung Park ... Keiko Tanaka-Yamamoto
    Long-term chemogenetic manipulation of specific cerebellar pathway involving ventral tegmental area revealed a critical role of the pathway as a proactive mediator of the stress-dependent development of depression-like behaviors.

    Loss of Doc2b does not influence transmission at Purkinje cell to deep nuclei synapses under physiological conditions

    Mehak M Khan, Wade G Regehr
    Eliminating the calcium-binding protein Doc2b does not alter transmission at a mature synapse under physiological conditions, counter to the prevailing view of Doc2b based on cultured neurons.

    Principles of operation of a cerebellar learning circuit

    David J Herzfeld, Nathan J Hall ... Stephen G Lisberger
    Quantitative analysis of behavior coupled with computational modeling reveal the set of circuit-level principles that underlie cerebellar-dependent motor learning in smooth pursuit eye movements of monkeys across timescales.

    Cerebellar associative sensory learning defects in five mouse autism models

    Alexander D Kloth, Aleksandra Badura ... Samuel S-H Wang
    Five mouse models of autism show deficits in delay eyeblink conditioning, a form of split-second sensory learning that involves the cerebellum, a frequent site of disruption in autistic brains.

    Entrained neuronal activity to periodic visual stimuli in the primate striatum compared with the cerebellum

    Masashi Kameda, Shogo Ohmae, Masaki Tanaka
    Neurons in the striatum exhibited periodic firing in monkeys attempting to detect omission of repetitive visual stimulus, while the phase of neuronal activity differed from that observed in the cerebellum.
    1. Neuroscience

    Anatomical and physiological foundations of cerebello-hippocampal interaction

    Thomas Charles Watson, Pauline Obiang ... Laure Rondi-Reig
    Anatomical tracing and physiological recordings reveal neuronal pathways through which the cerebellum may influence hippocampal activity.
