    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.

    Layer 2/3 pyramidal cells in the medial prefrontal cortex moderate stress induced depressive behaviors

    Prerana Shrestha et al.
    The well-established link between stress and depression could be due to the activity of a population of cells in prefrontal cortex that express a gene mutated in the rare disorder Wolfram syndrome.

    Serotonin: Slow motion

    Naoshige Uchida, Jeremiah Y Cohen
    Optogenetic stimulation of serotonin neurons in the dorsal raphe causes mice to move more slowly without causing any apparent motor deficits or anxiety-like effects.

    Threat of shock increases excitability and connectivity of the intraparietal sulcus

    Nicholas L Balderston et al.
    Multimodal neuroimaging was used to study the effect of threat on spontaneous brain activity and functional connectivity, and demonstrated that threat increases both activity and connectivity of the intraparietal sulcus, a key node in the frontoparietal attention network.

    Cyclooxygenase-2 inhibition reduces stress-induced affective pathology

    Joyonna Carrie Gamble-George et al.
    Mechanistically distinct COX-2 inhibitors reduce stress-induced behavioral pathology via unique multimodal molecular mechanisms, and could be used to treat mood disorders.

    HCN2 channels in the ventral tegmental area regulate behavioral responses to chronic stress

    Peng Zhong et al.
    HCN2 channels in the ventral tegmental area play an important role in the pathophysiology of chronic mild stress-induced behavioral deficits.

    Activation of the same mGluR5 receptors in the amygdala causes divergent effects on specific versus indiscriminate fear

    Mohammed Mostafizur Rahman et al.
    Activation of the same glutamate receptor in the lateral amygdala gives rise to distinct effects on specific versus indiscriminate fear by modulating intrinsic excitability and synaptic plasticity.

    Transient inhibition and long-term facilitation of locomotion by phasic optogenetic activation of serotonin neurons

    Patrícia A Correia et al.
    Phasic activation of dorsal raphe serotonin neurons transiently inhibits locomotion without influencing anxiety or producing reinforcement, but when repeated over many days a long-term facilitation of locomotion is produced.

    2018 Gairdner Awards: The past, present and future of light-gated ion channels and optogenetics

    Sheena A Josselyn
    Research into light-gated ion channels called channelrhodospins laid the foundations for the development of optogenetics, a technique that has gone on to revolutionize neuroscience.
