Rachmaninov prelude 23-5 by Evgeny Kissin

Rachmaninov prelude 23-5 by Evgeny Kissin is a must see must hear!!





One of 23 nonlinear coincidences???
Kissin is really talented ..

O Fortuna Carmina Burana

Sort of captures ... the day ...




"Carmina Burana" - 'Opening' (O Fortuna)

Music by Carl Orff (1895-1982)
Directed by Jean-Pierre Ponnelle
Munchner Rundfunkorchester
Chor des Bayerischen Rundfunks
Kurt Eichhorn, conductor (1975)

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]

Minsky and Money

Just listening to Marvin Minsky talking about the future and AI ...
so he says ... Money is of no use if nobody wants it ...
interesting

he recommends reading his Emotion Machine

Fernel's Final Causes

Yeah... you probably don't really know who Fernel was ... but he did say a few interesting things ... in particular
the seat of a final cause is in the brain


and that, my friends, nonlinear as it might seem ... is according to Sir Charles Sherrington in Man on His Nature ... and you just cant beat that!

The Hammer Fell

The hammer fell on Thursday ...
Friday was a totally nonlinear day
Today ... recovery starts

Modeling for Tech Visionaries

Modeling for Tech Visionaries by David E. Goldberg - Module 5: The Construction of Engineering Reality -- is pretty interesting ...

you can see it right here ...



check it out [via his blog]

but why haven't we heard from him anymore??

This raises brain questions --- if the brain senses some aspects of reality
why can't the brain sense itself ...possible problem with positive feedback loop???
