1. During anesthesia, the cortex is fully active, yet not conscious because the ascending signals are not forwarded by the reticular formation.
2. Only animals with neo-cortex have REM
3. It is possible that REM has to do with the consolidation of long term memory.
4. Posopagnosia: the condition of being unable to recognize faces that one sees.... even though one may be able to imagine the same faces.
5. The definition of consciousness: one prof gives that definition as follows: attention, self-reference, & awareness.... This sort of definition might require us to say that frogs catching flies are not conscious. Yet they are not zombies, robots. When we drive down a very, very familiar highway w/o paying attention to our driving, is our awareness of the road conditions "consciousness," is it like the frog catching the fly, or is it something different?
6. The binding problem: there is no one place in the brain where all cognition comes together, even though we experience being a one to whom everything happens.
7. (The claim that) we are able to grasp the experiences had by another as experiences had by another "I," thanks to mirror neurons.
8. That thalmic pain is an exception to the general rule that consciousness requires, consists of cortical activity.
9. That the ARAS (ascending reticular activation system) must stimulate the thalmus & cortex for it to be conscious; otherwise, a coma occurs.
10. That there are people who can see but are unaware that they can see. That is because area 17 in the back of the head is not functioning. Does information reach the cortex w/o having passed by area 17? How?
11. That some folks are color blind, not because of something wrong in the eye, but because of something gone wrong in the brain.
12. If one has motion agnosia, then one perceives what is moving as a series of still-frames...
13. (still re motion agnosia) The fact that motion agnosia is the result of a lesion to a particular part of the brain implies that the said part is responsible for perceiving the motion of things. And the latter fact shows that what is phenomenologically an aspect/moment of the given (i.e., the motion OF something) is cognized in virtue of a particular "piece" of the brain.
14. The normal path from seeing with the eye is retina, lateral geniculate, area 17 (back of the head), higher order visual cortex, higher level association area, pre-frontal cortex to PLAN the movement, then to the motor neurons or something like that to make it happen... (to be continued)
15. But it can happen that the information goes from the eye to the lateral geniculate to the amygdala (on the basis of the reticular formation's selective attention or shunting) without area 17's getting involved (think of us reacting like a frog that shoots its tongue out at a darting fly)
16. The species of agnosia called contralateral neglect indicates that spatial memory is referenced to one's body image!
17. That there are higher & lower visual areas (as well as auditory, etc.), and that these higher areas are necessary for sortal, motion, color and facial recognition.
18. That the limbic system subsumes learning, emotion and executive function.
19. That scientists have somehow wired a camera to a surface that touches the touch, with the result that the blind can see well enough to catch a ball. And the signals from the tongue go to the visual cortex (says phil of mind dude on teaching company lectures).
