One genetic variant of microcephalin arose approximately 30,000 years ago, which coincides
with the emergence of culturally modern humans, and it increased in frequency too
rapidly to be compatible with random genetic drift or population migration. |

The ASPM
gene variant arose about 5,800 years ago, coincident with
the spread of agriculture, cities,
and the first record of written language. It's high frequencies
in the population indicates strong positive

mammals have two

cortex, and primates
have three. |

The original
two regions of prefrontal
cortex, which are present in other mammals and evolved earlier, are the orbital prefrontal region, which
responds to external stimuli that are likely to be rewarding, and the anterior cingulate
cortex, which process information about the body's internal state. |

Orbital prefrontal region and the anterior cingulate cortex, the two original regions of prefrontal cortex work together to contribute to the emotional
aspects of decision
making. |

The third and new
region of prefrontal
cortex is called the
lateral prefrontal cortex and is where area 10 is. |

The new
region of lateral

Lateral prefrontal cortex is densely
interconnected with other regions that are larger in human brains -- the posterior parietal cortex and the temporal lobe cortex -- and outside the neocortex, it is connected to several cell
groups in the dorsal thalamus that are also disproportionately
enlarged, the medial dorsal nucleus and pulvinar. |

What has enlarged in human evolution is not a random group
of areas and nuclei, but an entire circuit. |

The lateral prefrontal cortex circuit has made humans more flexible and
capable of finding novel
solutions to problems. Included in this circuit is the ability to inhibit automatic responses, thereby permitting novel
responses. |

Cerebellum
is enlarged in humans. One part of the cerebellum, the dentate
nucleus in particular, is larger than expected. This area receives input neurons from the
lateral cerebellar cortex and send output neurons to the cerebral cortex via the thalamus. The thalamus sorts
and directs sensory information arriving from other parts of the nervous
system. Growing evidence that the cerebellum contributes to cognitive as well as motor function. |

For speech, each hemisphere is concerned with different aspects. Wernicke's area in the left
hemisphere recognizes distinctive parts of
speech, and an area in the right auditory cortex recognize prosody, the metric structure of speech. |

A component of Wernicke'sarea is larger in the left hemisphere than the right. Microscopic
architecture of Wernicke's
area is different from the corresponding part of the right
hemisphere -- many columns
are wider, and the spaces between them are
greater, and this lateralized change in
architecture is unique
to humans. |

Split-brain research has demonstrated that the left hemisphere has marked limitations in perceptual functions and the right hemisphere has prominent limitations in cognitive functions. |

seizure activity decreased 60 to 70%, and they felt just fine; no split

When you walk, talk, high jump,
etc, there is a collaboration among areas, from the sensory neurons up the spinal cord to the brainstem and eventually to the
cortex and back down through the basal ganglia, thalamic nuclei, cerebellum,
brainstem nuclei, and spinal cord to the interneurons and motor neurons. [Fuster's

The term artificial
intelligence (AI) originated in 1956, when John McCarthy from
Dartmouth, Marvin Minsky from Harvard, Nathaniel Rochester of IBM, and Claude
Shannon from Bell Telephone Laboratories, proposed a study of artificial intelligence to be
carried out during the summer of 1956 at Dartmouth College in Hanover, NH. |

John Searle
maintains that all conscious states are caused by lower-level brain processes; thus consciousness
is an emergent phenomenon, a physical property -- the sum of the input from the entire
body. Consciousness does not just
arise from banter back and forth in the brain. Consciousness is not the result of computation. You have to have
a body, and the physiology
of the body and its input, to create a mind that thinks and has
the intelligence of the human mind. |
