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.
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.
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.
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.
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.
A single astrocyte can decode neuronal activity and, consequently, release distinct gliotransmitters that differentially regulate neurotransmission at single hippocampal synapses.
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.
