    Probing the segregation of evoked and spontaneous neurotransmission via photobleaching and recovery of a fluorescent glutamate sensor

    Camille S Wang, Natali L Chanaday ... Ege T Kavalali
    Photobleaching and recovery of a fluorescent glutamate sensor enable demonstration of the distinct spatial architectures of spontaneous versus evoked forms of glutamatergic neurotransmission within single synapses.

    Slow fluctuations in ongoing brain activity decrease in amplitude with ageing yet their impact on task-related evoked responses is dissociable from behavior

    Maria Ribeiro, Miguel Castelo-Branco
    The explanation of why older people show increased behavioral variability despite having decreased neural signal variability lies in the link between the dynamics of the ongoing neural signal and the trial-by-trial variability of neural evoked responses.

    Spatial signatures of anesthesia-induced burst-suppression differ between primates and rodents

    Nikoloz Sirmpilatze, Judith Mylius ... Susann Boretius
    Functional imaging (fMRI) across four mammalian species maps the brain areas engaging in burst-suppression activity during anesthesia, and uncovers differences between primates and rodents.

    Synapses: Dividing communication, at the nanoscale

    Amelia J Ralowicz, Michael B Hoppa
    Fluorescent glutamate sensors shed light on the microscopic organization underlining spontaneous neurotransmission.

    Contractile force assessment methods for in vitro skeletal muscle tissues

    Camila Vesga-Castro, Javier Aldazabal ... Jacobo Paredes
    A standardized comparison of contractile force among in vitro muscle tissues across different platforms requires proper normalization with the contractile area and complementary morphological, maturation, and functional analysis to reduce variability and boost a new generation of engineered constructs.

    Human visual gamma for color stimuli

    Benjamin J Stauch, Alina Peter ... Pascal Fries
    Colored surfaces induce gamma oscillations in human early visual cortex that are equally strong for red and green colors when L-M cone contrast is controlled for.

    Mapping brain-wide excitatory projectome of primate prefrontal cortex at submicron resolution and comparison with diffusion tractography

    Mingchao Yan, Wenwen Yu ... Zheng Wang
    A comprehensive excitatory projectome of the ventro-lateral prefrontal cortex in macaques was generated by using viral tracing integrated with serial two-photon tomography and diffusion tractography, thus providing new evidence of rejecting the monosynaptic connection of inferior fronto-occipital fasciculus in monkeys.

    Role of anterior insula cortex in context-induced relapse of nicotine-seeking

    Hussein Ghareh, Isis Alonso-Lozares ... Nathan J Marchant
    The anterior insula cortex is a critical neural substrate of context-induced relapse of nicotine-seeking.

    A discrete parasubthalamic nucleus subpopulation plays a critical role in appetite suppression

    Jessica H Kim, Grace H Kromm ... Matthew E Carter
    The hypothalamic parasubthalamic nucleus can be subdivided into two distinct populations, one of which decreases food consumption and is necessary for the full appetite-suppressing effects of anorexigenic hormones.

    Prefrontal-amygdalar oscillations related to social behavior in mice

    Nahoko Kuga, Reimi Abe ... Takuya Sasaki
    The dorsal medial prefrontal cortex and basolateral amygdala exhibit social behavior-relevant neuronal oscillations, representing unified pathophysiological mechanisms underlying social behavioral deficits.
