    Amygdala neural activity reflects spatial attention towards stimuli promising reward or threatening punishment

    Christopher J Peck, C Daniel Salzman
    Primate amygdala neurons provide a coordinated representation of space and motivational significance whereby amygdala responses to visual stimuli predicting either rewards or aversive stimuli could influence spatial attention in a similar manner.

    Extinction recall of fear memories formed before stress is not affected despite higher theta activity in the amygdala

    Mohammed Mostafizur Rahman et al.
    When the fear-enhancing effects of prior exposure to stress are absent, the expression of fear reflects normal neural activity in the medial prefrontal cortex, not stress-induced hyperactivity in the amygdala.

    Optogenetic dissection of basolateral amygdala contributions to intertemporal choice in young and aged rats

    Caesar M Hernandez et al.
    Optogenetic approaches in young and aged rats define multiple roles for basolateral amygdala in guiding intertemporal choice, and show that these roles change across the lifespan.

    Primate amygdala neurons evaluate the progress of self-defined economic choice sequences

    Fabian Grabenhorst et al.
    Neurons in the amygdala, a brain system usually associated with emotion, track progress during sequential reward-directed choices according to an internal plan in Rhesus macaques.

    Cell-type-specific control of basolateral amygdala neuronal circuits via entorhinal cortex-driven feedforward inhibition

    E Mae Guthman et al.
    Sst+ interneurons drive feedforward inhibition in the basolateral amygdala, and thus provide a framework for why interneuron subtypes may mediate different archetypal circuit motifs across different brain regions.

    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.

    Instructed knowledge shapes feedback-driven aversive learning in striatum and orbitofrontal cortex, but not the amygdala

    Lauren Y Atlas et al.
    While the striatum and orbitofrontal cortex learn about threats through verbal warnings, the amygdala learns only from direct experience, suggesting that the amygdala forms part of a specialized threat detection system.

    Sex-specific processing of social cues in the medial amygdala

    Joseph F Bergan et al.
    Male and female mice respond differently to the same pheromone signals, and the representation of these sensory stimuli by neurons in the medial amygdala correlates precisely with the differences in behavior.

    Social interaction-induced activation of RNA splicing in the amygdala of microbiome-deficient mice

    Roman M Stilling et al.
    Social-interaction impairment in germ-free mice is associated with a markedly altered transcriptional response to social novelty in the amygdala, as characterised by replacement of upregulation of common stimulus-induced pathways with upregulation of the splicing machinery.

    Axon TRAP reveals learning-associated alterations in cortical axonal mRNAs in the lateral amgydala

    Linnaea E Ostroff et al.
    A diverse assortment of mRNAs are present in projection axons in the adult forebrain and their translation is associated with new memory formation.
