When sharing a space with others, many species including humans evolved compromise regulating occupancy influenced by social determinants. For example, students in classroom tend to sit close their friends, keeping the same spots across days, revealing structure classroom. This place preference suggests that factors such as hierarchy and affiliation can shape utilization; contrasting random walk models of agents moving at any given direction. Here, we asked whether spatial macaques (Macaca...
There is a vast and ever-accumulating amount of behavioural data on individually recognised animals, an incredible resource to shed light the ecological evolutionary drivers variation in animal behaviour. Yet, full potential such lies comparative research across taxa with distinct life histories ecologies. Substantial challenges impede systematic comparisons, one which lack persistent, accessible standardised databases. Big-team approaches building databases offer solution facilitating...
The macaque genus includes 25 species with hugely diverse social systems, ranging from low to high tolerance organization. Such interspecific behavioral variability provides a unique model tackle the evolutionary foundation of primate brain. Yet, neuroanatomical correlates these grades remain unknown. To address this question, we analyzed post-mortem structural scans 12 species. Our results show that amygdala volume is subcortical predictor macaques’ tolerance, exhibiting larger than ones....
Primates live in highly social environments, where prosocial behaviors promote bonds and cohesion contribute to group members' fitness. Despite a growing interest the biological basis of nonhuman primates' interactions, their underlying motivations remain matter debate. We report that macaque monkeys take into account welfare peers when making behavioral choices bringing about pleasant or unpleasant outcomes monkey partner. Two macaques took turns decisions could impact own partner's. Most...
Economic choices between goods entail the computation and comparison of subjective values. Previous studies examined neuronal activity in orbitofrontal cortex (OFC) monkeys choosing different types juices. Three groups neurons were identified: offer value cells encoding individual offers, chosen juice identity juice, offer. The encoded variables capture both input (offer value) output (chosen decision process, suggesting that values are compared within OFC. Recent work demonstrates causally...
Economic choices between goods are thought to rely on the orbitofrontal cortex (OFC), but decision mechanisms remain poorly understood. To shed light this fundamental issue, we recorded from OFC of monkeys choosing two juices offered sequentially. An analysis firing rates across time windows revealed presence different groups neurons similar those previously identified under simultaneous offers. This observation suggested that economic decisions in modalities formed same neural circuit. We...
Inhibitory control, the inhibition of impulsive behaviours, is believed to be key in navigating a complex social environment. Species characterised by higher tolerance, living more groups, with diverse relationships, face uncertainty regarding outcome interactions and, therefore, would benefit from employing inhibitory strategies. To date, little known about selective forces that favour evolution control. In this study, we compared control skills three closely related macaque species which...
Abstract Videos with rich social and emotional content elicit natural behaviors in primates. Indeed, while watching videos of conspecifics, monkeys engage eye contact, gaze follow, reciprocate facial expressions. We hypothesized that the frequency timing eyeblinks also depends on signals contained videos. monitored four male adult macaques they watched conspecifics displaying expressions direct or averted gaze. The instantaneous blink rate all animals decreased during temporal synchrony...
Short-term memory is implicated in a range of cognitive abilities and critical for understanding primate evolution. To investigate the effects phylogeny, ecology sociality on short-term memory, we tested largest most diverse sample to date (421 non-human primates across 41 species) an experimental delayed-response task. Our results confirm previous findings that longer delays decrease performance species taxa. analyses demonstrate considerable contribution phylogeny over ecological social...
In humans, the attitude toward risk is not neutral and dissimilar between bets involving gains losses. The existence prevalence of these decision features in non-human primates are unclear. addition, only a few studies have tried to simulate evolution agents based on their risk. Therefore, we still ignore what extent Prospect theory’s claims evolutionarily rooted. To shed light this issue, collected data from nine macaques that performed or We confirmed overall behaviour coherent with...
Economic choices are characterized by a variety of biases. Understanding their origins is long-term goal for neuroeconomics, but progress on this front has been limited. Here, we examined choice biases observed when two goods offered sequentially. In the experiments, rhesus monkeys chose between different juices simultaneously or in sequence. Choices under sequential offers were less accurate (higher variability). They also biased favor second offer (order bias) and preferred juice...
Many animal species engage in various forms of solitary object play, but this activity seems to be particular importance primates. If playing objects constitute a valuable resource, and access such is limited, competitive context may arise. We inserted unique toy within mini-colony long-tailed macaque (Macaca fascicularis) compared their behaviors sessions without object. An automatic color-based 3D video device was used track the positions each toy, data categorized into 5 exclusive...
Abstract It has long been hypothesized that economic choices rely on the assignment and comparison of subjective values. Indeed, when agents make decisions, neurons in orbitofrontal cortex encode values offered chosen goods. Moreover, neuronal activity this area suggests formation a decision. However, it is unclear whether these neural processes are causally related to choices. More generally, evidence linking value signals brain remains correlational. We address fundamental issue using...
A series of studies in which monkeys chose between two juices offered variable amounts identified the orbitofrontal cortex (OFC) different groups neurons encoding value individual options (offer value), binary choice outcome (chosen juice), and chosen value. These variables capture both input output process, suggesting that cell OFC constitute building blocks a decision circuit. Several lines evidence support this hypothesis. However, previous experiments offers were presented...
3,4-methylenedioxy-N-methyl amphetamine (MDMA) is one of the few known molecules to increase human and rodent prosocial behaviors. However, this effect has never been assessed on social behavior non-human primates. In our study, we subcutaneously injected three different doses MDMA (1.0, 1.5 or 2.0mg/kg) a group three, socially housed, young male long-tailed macaques. More than 200 hours behavioral data were recorded, during 68 sessions, by an automatic color-based video device that tracked...
Using sharp electrode impalement, action potentials recorded from atrial and ventricular tissue of pink salmon Oncorhynchus gorbuscha generally decreased in duration with increasing test temperature (6, 10, 16 20° C). Stimulation the using 500 nM adrenaline had no significant effect on potential at any but lengthened by ~17%.
Un des objectifs recherches en cognition chez les primates est de comprendre l'histoire évolutive leurs capacités cognitives. De grands échantillons provenant d'un large éventail d'espèces sont essentiels pour atteindre ce but. Cependant, la fiabilité inférences évolutives résultant ces études souffre souvent d'échantillons réduits, limités à une poignée d'individus et d'espèces. Le projet ManyPrimates propose surmonter limitations fournissant un cadre collaboratif grande échelle l'intention...
Blood sampling from awake non-human primates (NHPs) is classically performed under constraint in the cephalic or saphenous vein. It a challenging, potentially harmful and stressful procedure which may lead to biased results raises ethical concerns. Laboratory NHPs undergo head-restrained allowing for safer of collecting blood their ears. Using regular capillary collection devices 500 µL can be easily withdrawn per puncture point, sufficient performing most usual modern biological assays....
Primates live in complex social environments, where individuals create meaningful networks by adapting their behavior according to past experiences with others. Although free-ranging primates do show signs of reciprocity, experiments more controlled environments have mainly failed reproduce such dynamics. Hence, the cognitive and neural processes allowing monkeys reciprocate during exchanges remains elusive. Here, pairs long-tailed macaques (Macaca fascicularis) took turns into a decision...
