    Dynamic behavior of the locus coeruleus during arousal-related memory processing in a multi-modal 7T fMRI paradigm

    Heidi IL Jacobs et al.
    By combining ultra-high-field imaging with physiological and saliva measures it is established that interactions between locus coeruleus, hippocampus and amygdala vary along emotional memory stages, putatively reflecting distinct cognitive states.

    mPFC spindle cycles organize sparse thalamic activation and recently active CA1 cells during non-REM sleep

    Carmen Varela, Matthew A Wilson
    Sleep spindles provide a temporal framework to organize the reactivation of behaviorally relevant CA1 cells and sparsely active cells in the limbic thalamus.

    Dopaminergic modulation of the exploration/exploitation trade-off in human decision-making

    Karima Chakroun et al.
    Dopamine attenuates exploration during decision-making via a reduction of neural tracking of uncertainty.

    Preparation for upcoming attentional states in the hippocampus and medial prefrontal cortex

    Eren Günseli, Mariam Aly
    Memory guides attention by enabling preparation for upcoming states in the hippocampus and medial prefrontal cortex.

    Cerebellar Purkinje cell activity modulates aggressive behavior

    Skyler L Jackman et al.
    Optogenetic control of Purkinje cells in the cerebellar vermis enables bidirectional control of aggression.

    Dual orexin and MCH neuron-ablated mice display severe sleep attacks and cataplexy

    Chi Jung Hung et al.
    New transgenic mice, which can be ablated both orexin neurons and MCH neurons, showed new brain state and revealed functional interaction that MCH neurons have protective role in narcolepsy symptoms.

    Distinct neural contributions to metacognition for detecting, but not discriminating visual stimuli

    Matan Mazor et al.
    Combining psychophysics and functional MRI reveals a qualitative asymmetry in neural engagement when reflecting on whether a stimulus is seen (detection) compared to reflecting on what a stimulus is (discrimination).

    Diminished responses to bodily threat and blunted interoception in suicide attempters

    Danielle C DeVille et al.
    People who have attempted suicide exhibit blunted sensory processing during breathing and pain perturbations, as well as lower heartbeat perception accuracy and reduced mid/posterior insula activity during interoceptive attention.

    Temporal chunking as a mechanism for unsupervised learning of task-sets

    Flora Bouchacourt et al.
    Model-based analyses of human behaviour and neural activity show that representations of concurrent task-sets emerge by merging together representations of individual stimulus-response associations that occur in temporal proximity.

    Altered corticolimbic connectivity reveals sex-specific adolescent outcomes in a rat model of early life adversity

    Jennifer A Honeycutt et al.
    Early life adversity led to hyper-innervation from the basolateral amygdala to the prefrontal cortex earlier in females than males and disrupted maturation of functional connectivity, which predicted anxiety-like outcomes.
