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.
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.
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.
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 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.
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.
fMRI data from macaques suggest that sounds with similar temporal characteristics activate neighbouring regions of auditory cortex, giving rise to a topographic map broadly analogous to that for sound frequencies.
Primate attention is not limited to a dorsal fronto-parietal network, but includes a ventral temporal node and its dorso-ventral interactions with other attentional areas.
