Brains


The brains . . .

apes and humans have large heads and brains

(relative to body size)


Human and Ape Brains

The brains . . .

the large brains of apes and humans are also more developed than those of other animals

Lateral view of the brain. The illustration shows the increase in the

cerebral cortex of the brain. The cerebral cortex integrates sensory

information and selects responses.

Understanding Physical Anthropology and Archaeology, 9th ed., p. 107


The brains . . .

humans have highly developed frontal and occipital regions of the brain . . .


The brains . . .

occipital region =

curved back and base

of the skull


Gracile Australopithecus / Homo Lineage Brain

Humankind Emerging, 7th ed., p. 390


The brains . . .

cerebrum =

  • large rounded structure of the brain

  • largest part of the brain

  • comprises ca. 85% of the brain’s total weight

cerebral cortex of the brain. The cerebral cortex integrates sensory

information and selects responses.

The brains . . .

The cerebral cortex

(neocortex)

increases in area


The brains . . .

cerebral cortex =

neocortex =

thin layer of grey matter covering the cerebrum


The brains . . .

in humans the cerebral cortex lies in folds or “convolutions” over the entire surface of the cerebral hemisphere


The brains . . .

prehistorically the convoluted cerebral cortex can often be seen in “endocasts”


The brains . . .

endocasts =

fossilized casts of the interior of a skull


The brains . . .

humans also have

well-developed “association” areas . . .


The brains . . .

association areas are thought to be involved in learning, memory, thinking, and bringing together information form the various senses


The brains . . .

association areas =

regions of the cerebral hemispheres thought to serve some integrative function . . .
