    Ultra-high-field imaging reveals increased whole brain connectivity underpins cognitive strategies that attenuate pain

    Enrico Schulz et al.
    A single-trial whole-brain analysis of three cognitive strategies to attenuate pain shows that a more effective pain attenuation is associated with increased functional connectivity across the entire brain.

    Mesoscopic-scale functional networks in the primate amygdala

    Jeremiah K Morrow et al.
    Multivariate data decomposition applied to local field potentials recorded from the primate amygdala revealed simultaneously active and functionally distinct networks, defined by anatomical boundaries between the nuclei.

    Extensive and spatially variable within-cell-type heterogeneity across the basolateral amygdala

    Timothy P O'Leary et al.
    Basolateral amygdala excitatory neurons are a highly heterogenous collection of neurons that spatially covary in molecular, cellular, and circuit properties.

    Alterations of specific cortical GABAergic circuits underlie abnormal network activity in a mouse model of Down syndrome

    Javier Zorrilla de San Martin et al.
    Distinct intrinsic excitability and synaptic dysfunctions in specific cortical inhibitory circuits lead to abnormal network activity in a mouse model of Down syndrome.

    Minimally dependent activity subspaces for working memory and motor preparation in the lateral prefrontal cortex

    Cheng Tang et al.
    The evidence of subspace computation in the lateral prefrontal cortex provides insights into the neural mechanisms underlying cognitive flexibility and interference between different cognitive processes.

    Neural arbitration between social and individual learning systems

    Andreea Oliviana Diaconescu et al.
    Arbitration is formalised as the relative precision of predictions afforded by reward and social learning systems and is represented in modality-specific dopaminergic and dopaminoceptive regions, including the midbrain and amygdala.

    The frequency gradient of human resting-state brain oscillations follows cortical hierarchies

    Keyvan Mahjoory et al.
    The strongest peak frequency of brain oscillations in a brain area decreases significantly, gradually and robustly along the posterior-anterior axis following the global hierarchy from early sensory to higher order areas.

    Amphetamine reduces reward encoding and stabilizes neural dynamics in rat anterior cingulate cortex

    Saeedeh Hashemnia et al.
    Amphetamine reduces reward signaling by neurons in rat prefrontal cortex, but increases the stability of population dynamics, which account for animals’ increased task engagement, despite reduced reward motivation.

    Learning prediction error neurons in a canonical interneuron circuit

    Loreen Hertäg, Henning Sprekeler
    The formation and refinement of prediction error circuits relies on an experience-dependent balance of excitation and inhibition in canonical microcircuits.

    Heterogeneous somatostatin-expressing neuron population in mouse ventral tegmental area

    Elina Nagaeva et al.
    The midbrain area for salience, reward and aversion in mouse brain harbours among the dopamine cells three subtypes somatostatin-expressing neurons that show combinatorial neurotransmitter phenotypes and interneuron properties.
