    Group-specific archaeological signatures of stone tool use in wild macaques

    Lydia V Luncz et al.
    Tool behaviour of long-tailed macaques leaves archaeological signatures that differ between populations despite similar ecological conditions, highlighting the potential for diversity in material culture.

    Behavioral evidence for memory replay of video episodes in the macaque

    Shuzhen Zuo et al.
    Macaque monkeys temporally compress past experiences and use a forward-replay mechanism during judgment of temporal-order between episodes.

    Receptor-driven, multimodal mapping of cortical areas in the macaque monkey intraparietal sulcus

    Meiqi Niu et al.
    The macaque monkey intraparietal sulcus encompasses 17 cyto- and receptorarchitectonically distinct areas, which can be grouped into three clusters based on (dis)similarities of their molecular structure.

    Fast and reversible neural inactivation in macaque cortex by optogenetic stimulation of GABAergic neurons

    Abhishek De et al.
    Optogenetic activation of cortical GABAergic cells in macaques yields robust and reversible behavioral deficits.
    1. Neuroscience

    Mediodorsal thalamus is required for discrete phases of goal-directed behavior in macaques

    Evan Wicker et al.
    Transient suppression of activity in the macaque mediodorsal thalamus impairs adjustment of secondary reinforcer values and disrupts appropriate action selection in a reinforcer devaluation task; this profile is distinct from that of amygdala or subregions of orbitofrontal cortex.

    Sequential selection of economic good and action in medial frontal cortex of macaques during value-based decisions

    Xiaomo Chen, Veit Stuphorn
    Whenever monkeys are required to choose between multiple options, neural responses indicate that they first select the desired outcome and then use this information to guide their actions.

    A neural mechanism of speed-accuracy tradeoff in macaque area LIP

    Timothy Hanks et al.
    To establish a trade-off between the speed and accuracy of a decision, neurons in lateral intraparietal cortex combine evidence bearing on the decision with a signal that incorporates the cost of time into the decision-making process.
    1. Neuroscience

    Neuronal activity determines distinct gliotransmitter release from a single astrocyte

    Ana Covelo, Alfonso Araque
    A single astrocyte can decode neuronal activity and, consequently, release distinct gliotransmitters that differentially regulate neurotransmission at single hippocampal synapses.
    1. Neuroscience

    Neuronal representation of saccadic error in macaque posterior parietal cortex (PPC)

    Yang Zhou et al.
    Neurons in the macaque posterior parietal cortex behave like an error detector that computes the saccadic error by comparing the intended and the actual saccade end-position signals.
    1. Neuroscience

    Distinct spatial coordinate of visual and vestibular heading signals in macaque FEFsem and MSTd

    Lihua Yang, Yong Gu
    In both frontal and temporal–parietal visual cortices of macaque, distinct spatial coordinates of visual and vestibular signals are predominantly eye centered and head centered, respectively.
