Bran is not a computer in traditional Turing Machine sense

Variability of brain structure

Galileo

Rene Decarte

William James

Wilhelm Wundt

6 cortical layers

75% neurons die at final stage of embryogenesis

Perception is context dependent

Abandoned reductionism

Charles Darwin: Variation is not noise, but preparation for the future

TNGS: Theory of Neuronal Group Selection (Gerald Edelmann)

Neural Darwinism

Stage 1: Creation of repertoire of circuit during embryogenesis by epigenic variation and selection (Developmental Selection) – Neurons that fire together, wire together.

Stage 2: Selection among diverse pre-existing circuits by differential amplification of synaptic strength. (Environmental Selection)

Stage 3: Reentrant Mapping

Degeneracy: different neural structure, same performance

02 The Emergence of Intelligence in the Neocortical Microcircuit

Henry Markram, EPFL/BlueBrain

1 hr 9 min 33 sec - May 10, 2006

www.almaden.ibm.com

Lecture 2 of 12 of IBM Research's Almaden Institute Conference on Cognitive Computing. Markram discusses microcolumns in the brain, and shows several video animations of computer models of neurons communicating in a microcolumn. His model includes 10,000 neurons, which is a *very* large number of neurons to model.

03 The Mechanism of Thought

Robert Hecht-Nielsen - Wikipedia, the free encyclopedia

Robert Hecht Nielsen Home page

In March, 2005, he held an event to announce "the fundamental mechanism of cognition", which he believes is a process of confabulation. He posits that all actions and thoughts begin as the "winners" of competitions, where confabulations are tested for cogency based on antecedent support. He presented some mathematical models of the proposed mechanism, and some experimental results where software using this system was able to add several words to a stub of a sentence, keeping that stub coherent and, optionally, maintaining some connection to a full input sentence supplied as context.

Lecture 3 of 12 of IBM Research's Almaden Institute Conference on Cognitive Computing.

Hecht-Nielsen discusses sentence generation based on knowledge links. It's so good, it appears to generate new sentences based on strong semantic understanding of the input sentences. He also demonstrates robust speech understanding. His work is sponsored by Fair Isaac and the Office of Naval Research.

06 The Uniqueness of the Human Brain

V. S. Ramachandran, UCSD

54 min 2 sec - May 10, 2006

www.almaden.ibm.com

Lecture 6 of 12 of IBM Research's Almaden Institute Conference on Cognitive Computing. This one takes place during the reception and banquet dinner.

Ramachandran discusses phantom limbs and synesthesia (esp. color-blind synesthete) as a function of neuron innervation. Specifically, he focuses on cross-linking between nearby cortical regions, which he believes to be genetically caused (e.g. synesthesia appears to be found frequently in family lineages). He also discusses the link between mirror neurons and autism, and how language invention is due to an inherent cross-linking between portions of the visual and auditory regions (e.g. Buba/Kiki effect).

07 Beyond Dualism

John Searle, UC Berkeley

1 hr 17 min 34 sec - May 11, 2006

www.almaden.ibm.com

Lecture 7 of 12 of IBM Research's Almaden Institute Conference on Cognitive Computing.

1959 Prof. in UC Berkeley

Philosophy of language / mind

Consciousness: social construction, physical reality

Thought experiment: Chinese room argument

Computer do not have to understand language in order to process information

Rationality and Action,

Mind,

Liberty and Neurobiology

Dualism vs. Materialism

Conscious without being self-conscious

All conscious states:

qualitativeness

subjectivity,

Epistemic vs. ontologic sense of objectivity

Entity with Ontological Subjectivity of existence: pain, tickle, itch

Ontological objectivity: mountain,

Epistemic objectivity does not exclude ontological subjectivity

Intensionality (meaning any mental states in philosophy)

Observer independent intensionality

All conscious states as part of unified conscious feel

Therefore

can not be reduced

all states caused by neuronal activity

realized in the brain, not in single neuron

a higher level feature caused by lower level activity

functions causally

ontologically irreducible

causally reducible

problem of computationalism

computer program handle syntax, but not semantic – Chinese room argument

psychologically real vs. unreal programs

observer vs. non-observer relative information

information

intelligence

artificial intelligence implies not real intelligence ?

simulation of intelligence is not producing intelligence artificially

NCC Neuronal Correlation of Consciousness

2 approaches to consciousness

Unified field approach
Building block approach

Binocular rivalry: Duck-rabbit (ambiguous picture) cognitive switch – winner takes all

Tracking stimulus

Francis Crick: studying consciousness is harder than DNA

Different levels of description

Materialism is true in saying universe is consist of materials, but wrong in saying consciousness can not exist

Dualism is true in saying there is consciousness, which is a irreducible neurobiological phenomenon, but wrong in saying, therefore it must be in a different realm

Unintensional anxiety: nervousness about anything

Freud: aim of psychoanalysis is to replace misery of neurosis with ordinary human unhappiness

Psychoanalyst: our job is to convert undirected anxiety to directed anxiety

Simulation is not duplication
