Neural Science Notes

Nonliner, Nonelephant, Nonnonsense, Nonintutive??

from Kendal et al's Principles of Neural Science
[Google Scholar reports about 2,726 items citing Kandel: Principles of Neural Science] - definitely look at T. Albright, T. Jessell, E. Kandel, M. Posner Neural ScienceA Century of Progress and the Mysteries that Remain. Cell, Volume 100, Pages 1-55 [PDF here].






  • Knowledge not stored as complete representation; rather its divided into distinct categories - stored separately

  • sense of self consciousness - the I - is sum of connections of independent circuits

  • Sperry & Gazzaniga: cut corpus callosum situation indicated separate consciousness for left and right hemispheres.

  • Biology's deepest riddle: neural representation of consciousness and self-awareness



Minsky thinks neurologists are doing the wrong experiments because they don't have good theories ... for example the issue of mirror neurons ... he believes that those represent goals ... Again he recommend reading The Emotion Machine: Commonsense Thinking, Artificial Intelligence, and the Future of the Human Mind
Some student asks: What are thoughts?


NP Notes:

what is really observed:
a) structure - via mircroscope slices, X-Rats, MRI, Ultrasound
b) function - via region activation [PET ...)
c) electrophysioligical traces [spikes ..}
d) time series of different normal and abnormal phenomena [like voltage/current across synpase, ... or propagation aling nerve axons... associated with different conditions [disease, or induced,eg via chemical or light or sound inputs]
