    A critical residue in the α1M2–M3 linker regulating mammalian GABAA receptor pore gating by diazepam

    Joseph W Nors et al.
    The role of an important gating domain in linkage between the benzodiazepine drug-binding site and the pore gate in GABAA receptors.

    Modulation of anxiety and fear via distinct intrahippocampal circuits

    Elif Engin et al.
    The hippocampus features a double dissociation in its circuits with respect to the regulation of fear and anxiety, with CA3 and the dentate gyrus implicated in anxiety and CA1 in fear.

    Axonal mechanisms mediating γ-aminobutyric acid receptor type A (GABA-A) inhibition of striatal dopamine release

    Paul F Kramer et al.
    GABA-A receptors on dopamine neuron axons not only depolarize the membrane but also limit action potential propagation, an effect potentiated by positive allosteric modulators of GABA-A receptors like diazepam (Valium).

    Risk of punishment influences discrete and coordinated encoding of reward-guided actions by prefrontal cortex and VTA neurons

    Junchol Park, Bita Moghaddam
    Risk of punishment during reward seeking behavior is associated with a functional "disconnection" of the PFC-VTA circuit due to a transient loss of VTA-driven theta oscillation.

    Involvement of the Acyl-CoA binding domain containing 7 in the control of food intake and energy expenditure in mice

    Damien Lanfray et al.
    The Acyl-CoA binding domain-containing 7 (Acbd7) gene is expressed in the hypothalamus, encodes a peptide that suppresses appetite, increases metabolic rate and interacts with the leptin-melanocortin system.

    Cryo-EM structure of the benzodiazepine-sensitive α1β1γ2S tri-heteromeric GABAA receptor in complex with GABA

    Swastik Phulera et al.
    Structure of the triheteromeric α1β1γ2S GABAA receptor in complex with GABA illuminates the principles of receptor assembly and agonist binding.

    Mouse brain transcriptome responses to inhaled nanoparticulate matter differed by sex and APOE in Nrf2-Nfkb interactions

    Amin Haghani et al.
    Transcriptome analysis of mouse brain revealed that the APOE4 allele and sex can alter air pollution neurotoxicity in adults.
    1. Neuroscience

    The recovery of standing and locomotion after spinal cord injury does not require task-specific training

    Jonathan Harnie et al.
    Restoring locomotion after complete spinal cord injury does not require locomotor training, only the return of sufficient excitability within neurons of the spinal cord.
    1. Neuroscience

    Specialized areas for value updating and goal selection in the primate orbitofrontal cortex

    Elisabeth A Murray et al.
    Within the monkey orbitofrontal cortex, a posterior part learns new values, whereas an anterior part translates this knowledge into advantageous decisions.
    1. Neuroscience

    A high-throughput neurohistological pipeline for brain-wide mesoscale connectivity mapping of the common marmoset

    Meng Kuan Lin et al.
    A systematic high-throughput neurohistological and computational pipeline for marmoset which establishes a foundational setup in brain mapping and circuit tracing to support current and emerging research in primate studies.
