Brain structure and emotional responses

line

Hypothetical ideas about cerebral neurons and the behavior of neuronal receptors (complex proteins) have revealed important facts on which opinions, such as George Lakoff's have been constructed.

The structure and function of the brain's diversified parts remain difficult to implicate in behavioral responses and emotional states.

We know for example that structurally the human brain shares with our ancestors three formative parts:

  1. limbic system resembles structures in the reptilians (hypothalamus and related structures)
  2. psycho- sensory-motor system, including the brain stem and the optic chiasm, resembles structures in the mammalian brains.
  3. human's prefrontal cortex while more developed is tied to the cerebral cortex that resembles primate brains.

Lakoff insists that current brain research sustains his assertions, and to illustrate this he refers to what we have discovered that neurons do to substantiate his conclusions that narratives create a necessary sense of purpose in human thought.

“neural binding can create emotional experiences. In the area of the limbic system, the oldest part of the brain in terms of evolution, there are two emotional pathways with different neurotransmitters: one for positive emotions—the dopamine circuit—and one for the negative emotions—the norepinephrine circuit.”

P. 27.

“There are pathways in the brain linking these emotional pathways to the forebrain, where dramatic structure circuitry seems most likely to be located.”

pp. 27-28.


“Activations of such convergent pathways are called ‘somatic markers.’ It is they that neurally bind the emotions (downstream, near the brain stem) to event sequences in a narrative (upstream, apparently in the prefrontal cortex, at the front and top of the brain). The somatic markers allow the right emotions to go where they should in a story. They are the binding circuits responsible for the emotional content of everyday experiences.”

p. 28.


Eve, the serpent, and Adam in the garden of eden form the quintessential Christian narrative.

 

“Narratives and frames are not just brain structures with intellectual content, but rather with integrated intellectual-emotional content. Neural binding circuitry provides this integration.”

p. 28.

“We live in our narratives. The lived story is at the center of modern personality theory. The theory of neural computation … shows how our brains not only permit this, but favor it.”

“Narratives and frames” -- “means they are instantiated in our brains.”


“The roles in narratives that you understand yourself as fitting give meaning to your life, including the emotional color that is inherent in narrative structures.”

p. 33.


“as we acquire the deep narratives, our synapses change and become fixed. A large number of deep narratives can be activated together. We cannot understand other people without such cultural narratives. But more important we cannot understand ourselves—who we are, who we have been, and where we want to go–without recognizing and seeing how we fit into cultural narratives.”

pp. 33-34.
