    Pedunculopontine glutamatergic neurons control spike patterning in substantia nigra dopaminergic neurons

    Daniel J Galtieri et al.
    Pedunculopontine neurons can evoke burst spiking in substantia nigra dopaminergic neurons without engaging a subtype of glutamate receptor previously thought to be necessary for this spiking mode.

    Protein-mediated RNA folding governs sequence-specific interactions between rotavirus genome segments

    Alexander Borodavka et al.
    In rotaviruses, the selective packaging of eleven distinct genomic RNA segments requires virus-encoded protein NSP2 to alter the RNA structures, facilitating their interactions with each other.

    Attenuation of dopamine-modulated prefrontal value signals underlies probabilistic reward learning deficits in old age

    Lieke de Boer et al.
    Attenuated anticipatory activity in ventromedial prefrontal cortex is modulated by dopamine D1 receptor density in nucleus accumbens, and accounts for impaired probabilistic reward learning in older adults.

    Embryonic transcription factor expression in mice predicts medial amygdala neuronal identity and sex-specific responses to innate behavioral cues

    Julieta E Lischinsky et al.
    Studying the development of the medial amygdala in the mouse reveals how the brain may potentially process sex differences in innate behaviors such as mating.

    Cellular and neurochemical basis of sleep stages in the thalamocortical network

    Giri P Krishnan et al.
    A computational model of the thalamocortical network explains sleep stages by the coordinated variations in the level of neuromodulators and predicts differences of sleep pattern in human, cat and mouse recordings.

    Transformation of spatiotemporal dynamics in the macaque vestibular system from otolith afferents to cortex

    Jean Laurens et al.
    The spatial and dynamic properties of self-motion signals are acquired at the first stage of otolith signal transformation, which is in the brainstem and cerebellum, and conserved across brainstem, cerebellar and cortical areas.

    Direct assessment of substrate binding to the Neurotransmitter:Sodium Symporter LeuT by solid state NMR

    Simon Erlendsson et al.
    Solid state NMR is unable to detect any association of substrate to the second binding site, S2, in the extracellular vestibule of the Neurotransmitter:Sodium Symporter LeuT.

    Functional integration of a serotonergic neuron in the Drosophila antennal lobe

    Xiaonan Zhang, Quentin Gaudry
    Serotonergic cells innervating the Drosophila antennal lobe are inhibited by odors and modulate olfactory responses in conjunction with the entire serotonergic network.

    Ring-like oligomers of Synaptotagmins and related C2 domain proteins

    Maria N Zanetti et al.
    A model for synchronous neurotransmitter release suggests that when not in the presence of calcium ions, Synaptotagmin proteins form ring-like structures between the vesicle and plasma membrane that prevent spontaneous fusion.

    AMPK acts as a molecular trigger to coordinate glutamatergic signals and adaptive behaviours during acute starvation

    Moloud Ahmadi, Richard Roy
    AMP-activated protein kinase directly coordinates glutamatergic signalling during starvation in C. elegans.
