  1. Class Slides Set16B Brains

  2. The brains . . . apes and humans have large heads and brains (relative to body size)

  3. Human and Ape Brains Humankind Emerging, 7th ed., p. 389

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

  5. size . . . • complexity . . . • the ratio of brain weight to overall body weight . . . The brains develop in . . .

  6. size . . . • complexity . . . • the ratio of brain weight to overall body weight . . . The brains develop in . . .

  10. size . . . • complexity . . . • the ratio of brain weight to overall body weight . . . The brains develop in . . .

  11. 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

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

  13. The brains . . . occipital region = curved back and base of the skull

  14. Gracile Australopithecus / Homo Lineage Brain Humankind Emerging, 7th ed., p. 390

  15. The brains . . . cerebrum = • large rounded structure of the brain • largest part of the brain • comprises ca. 85% of the brain’s total weight

  16. 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

  17. The brains . . . The cerebral cortex (neocortex) increases in area

  18. The brains . . . cerebral cortex = neocortex = thin layer of grey matter covering the cerebrum

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

  20. The brains . . . prehistorically the convoluted cerebral cortex can often be seen in “endocasts”

  21. The brains . . . endocasts = fossilized casts of the interior of a skull

  22. The brains . . . humans also have well-developed “association” areas . . .

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

  24. The brains . . . association areas = regions of the cerebral hemispheres thought to serve some integrative function . . .

  25. Human Brain Humankind Emerging, 7th ed., p. 389

  26. size . . . • complexity . . . • the ratio of brain weight to overall body weight . . . (“brain weight / body weight ratio”) The brains develop in . . .

  27. Brain Weight – Body Weight Ratios Humankind Emerging, 7th ed., p. 386
