Sensing the world

Remembering the world

Living in the world & body - A strong case can be made for the idea that the world we perceive is much more detailed and coherent than our senses would seem to allow. Detailed vision is limited to a mere 4 degrees around the center of fixation of the eyes. Our eyes jump around (make saccades), yet we perceive a coherent, stable world. The brain is a simulator, a dream machine, not only during the night. Besides that, it also uses its own emotions (amygdala) to simulate and perceive those of other people. In the most extreme case, when one's own emotions are disturbed, friends can become perceived as being imposters. This is only one of the many devastating, yet instructive possible dysfunctions of the brain, called Capgras Syndrome. Language also has been suggested to involve simulation, in order to go from sounds back to the manipulation of a speaker's speech organ and intended phonemes.

  • To conclude, the line dividing the frontal and posterior parts of the neocortex (the central sulcus) should be seen as the interface between the brain and the muscles and the body's senses. The gateway to regulation of the body's autonomic functions is the hypothalamus. - More brain structures...
