Primate Brain Evolution
Prefrontal cortex in humans and apes
Area 10 is one of the cortical areas of the frontal lobe involved in higher cognitive functions such as the undertaking of initiatives and the planning of future actions. It is known to form the frontal pole of the macaque and human brain, but its presence and organization in the great and lesser apes remain unclear. It is here documented that area 10 also forms the frontal pole of chimpanzee, bonobo, orangutan, and gibbon brains. Imaging techniq…

Limbic frontal cortex in hominoids
The limbic frontal cortex forms part of the neural substrate responsible for emotional reactions to social stimuli. Area 13 is one of the cortical areas long known to be part of the posterior orbitofrontal cortex in several monkey species, such as the macaque. Its presence nevertheless in the human brain has been unclear, and the cortex of the frontal lobe of the great and lesser apes remains largely unknown. In this study area 13 was identified …

Relative brain size in monkeys and prosimians
Prosimians have smaller brains relative to their body sizes than do monkeys. Brain and body weights, however, are associated not only on the basis of the brain integrating sensorimotor functions, but also on the basis of the body's requirement to support the energetic needs of the brain. Prosimians differ from monkeys in that they have lower rates of oxygen turnover. When body size is adjusted for its rate of oxygen turnover, monkeys and prosimia…
Brain Size, Cranial Morphology, Climate, and Time Machines [and Comments and Reply]
A bioclimatic model is evaluated as an explanation of variation in cranial capacity among 122 ethnic groups. Distribution of absolute and relative endocranial volume is mapped. Significant correlations occur with all nine climatic variables examined. Major foci of adaptation occur with solar radiation, vapor pressure, and winter temperature. Global mean trait increase is 2.5 cm per degree of equatorial distance. The interactive geometry between c…

A quantitative comparison of the Hominoid Thalamus. IV. Posterior association nuclei—the pulvinar and lateral posterior nucleus
Nuclear volumes, nerve cell densities, numbers of neurons, and volumes of nerve cell perikarya in the thalamic association complex, the pulvinar and lateral posterior nuclei (Pu‐LP) were compared among two gibbons, one gorilla, one chimpanzee, and three humans. The human Pu has approximately twice as many neurons as do the great apes, whereas the human and gorilla LP have a similar number. The numbers of neurons in the human Pu and combined Pu‐LP…
A quantitative comparison of the hominoid thalamus
Structures in the limbic system are commonly thought to be similar in form and function in all mammalian brains. In the study reported here, two thalamic limbic nuclei, N. anterior principles and N. lateralis dorsalis, were compared among a group of extant of extant hominoids. The nuclear volumes, neuronal densities, number of neurons per nucleus, and volumes of neuronal perikarya were measured. Humans have much larger nuclei but the nuclei const…
A quantitative comparison of the hominoid thalamus
Nuclear volumes, nerve cell densities, numbers of neurons, and volumes of nerve cell perikarya of the thalamic ventrolateral complex (VL), a neural substrate for movement, were measured in specimens from two gibbons, one gorilla, one chimpanzee, and three humans, and the values were compared. The human VL had about one‐and‐a‐half times as many neurons as did those of the great apes. The relative frequencies of the sizes of nerve cell perikarya di…
A quantitative comparison of the hominoid thalamus. I. Specific sensory relay nuclei
Studies to date have indicated few differences in sensory perception among hominoids. Sensory relay nuclei in the dorsal thalamus‐portions of the medial and lateral geniculate bodies (MGBp, LGBd) and the ventrobasal complex (VB)—in two gibbons, one gorilla, one chimpanzee and three humans were examined for anatomical similarity by measuring and estimating the nuclear volumes, neuronal densities, numbers of neurons per nucleus, and volumes of neur…
