Notes on The Brain

 

Modern computer imaging technology has exploded the old cliché about left- and right-brained people into an extraordinarily precise map of cognitive skills: loud and soft sounds are processed in different areas, while the simple activity of touching your thumb and forefinger activates several areas of the brain at once, scattered widely across both lobes. The meaning of spoken language is stitched together out of the two familiar lobes -- the left side parsing the grammar, and the right side measuring the emotional content of the speaker's intonation -- but simply thinking of a word lights up regions of the visual cortex, while suppressing neuronal charges in the speech regions. While general intelligence remains an essential, defining quality of the human mind, it is clear now that we come into the world with countless other cognitive tools, engineered by natural selection for more specific tasks.

our phenomenological world -- the world as we experience it -- is determined at some level by the "wiring" in our brains. Thus, as we learn more about that wiring, the important job will not be to figure out how to avoid the collision of humanism and science, but to figure out how the two might better collaborate.  

Steven Rose: I don't take free will very seriously. I would say something different, and that is that we have to get rid of this whole attempt to create dichotomies between nature and nurture. The real thing about our brain development, our development as organisms, is not a dichotomy between nature and nurture, but a dichotomy between specificity and plasticity or perhaps between process and outcome. What is required is a developmental system which is partly not modified by the environment and partly capable of responding to the environment.

Intelligence Considered
Scientific American has a thoughtful piece on the meaning of intelligence.

Brain Fun

Mensa Brain Games
Mensa (which means "table" in Latin) was conceived as a kind of progressive society -- a round-table where race, color, creed would be irrelevant. The only thing that would matter, of course, would be a sky-high IQ. Mensa's homepage offers a challenging brain game.

Emotional Intelligence
Within the academic community, the response to Daniel Goldman's book Emotional Intelligence was tepid. But the book made waves among popular psychology readers. Take this Utne Reader quiz and determine your EQ.

brainwiring -- attention deficit disorder, more to come

 

"Anyone studying the mind will soon stumble across a fundamental tension between first-person and third-person accounts of cognition. On the one hand, you have three pounds of gray matter flowering on top of a post-simian spine -- meat that can be mapped, poked, drugged, and registered. On the other hand, you have your own internal flow of impressions, thoughts, sensations, and memories, a stream of consciousness that includes thoughts like "the stream of consciousness is an illusion." How can we integrate these two worlds? And is it even a good idea?"

>From Erik Davis' Essay, "This Is Your Brain On Buddha" in FEED

 

Antonio Damasio

We measure what we have theories for. (Einstein)

  1. molecular
  2. celular
  3. microcircuits
  4. macrocircuits
  5. behavior
  6. cognition
  7. social
  8. cultural

Three distinct parts of the brain concerned with knowledge and learning:

  1. learn facts -- hypocamus
  2. learn things --
  3. learn emotions -- amygdala
