The primate cerebral cortex is characterized by regional variation in the structure of
pyramidal neurons, with more complex dendritic arbors and greater spine density observed …

Among nonhuman primates, chimpanzees are well known for their sophistication and
diversity of tool use in both captivity and the wild. The evolution of tool manufacture and use …

Many historical and contemporary theorists have proposed that population‐level behavioral
and brain asymmetries are unique to humans and evolved as a consequence of human …

Differences in the psychological capacities of closely related species are likely due to
differences in their brains. Here, we review neuroanatomical comparisons between …

Whether lateralization of communicative signalling in non-human primates might constitute
prerequisites of hemispheric specialization for language is unclear. In the present study, we …

Determining the cellular composition of specific brain regions is crucial to our understanding
of the function of neurobiological systems. It is therefore useful to identify the extent to which …

Comparative cognition is the field of inquiry concerned with understanding the cognitive
abilities and mechanisms that are evident in nonhuman species. Assessments of animal …

The central sulcus (CS) divides the pre-and postcentral gyri along the dorsal-ventral plane of
which all motor and sensory functions are topographically organized. The motor-hand area …

Handedness, one of the most prominent expressions of laterality, has been historically
considered unique to human. This noteworthy feature relates to contralateral inter …

It has been hypothesized that neurological adaptations associated with evolutionary
selection for throwing may have served as a precursor for the emergence of language and …
