“Imagine something more mysterious than the trenches of the deep sea, more convoluted than the intricacies of the human genetic code, possibly even more infinite than the vastness of outer space...”
Question: What I think?Brain: “...an
apparatus with wich we think we think”; the physical and chemical platform for the mind; energy, signals, thoughts...
Phrenology Chart (1833)
“Thinking about Thinking”
…really, google it: “what I think?”
Internet meme: Brain-to-Brain-Interface-like
Limits of science
http://en.wikipedia.org/wiki/Meme
• The word meme is a shortening (modeled on gene) of mimeme and it was coined by the British evolutionary biologist Richard Dawkins in The Selfish Gene (1976) as a concept for discussion of evolutionary principles.
• The meme, analogous to a gene, was conceived as a "unit of culture" (an idea, belief, pattern of behaviour, etc.) which is "hosted" in one or more individual minds, and which can reproduce itself, thereby jumping from mind to mind.

•Cognitive• Reason (make judgment under uncertainly)
• Consciousness
• Represent knowledge (also commonsense)
• Plan
• Learn (critical to human intelligence)• Communicate (natural language)
• Self-awareness, Sentience, Sapience...
Hypothesis: How I think?

•Conative• Natural
tendency?, impulse…
mind loop:Sensation > Perception >Action >Emotion >
• The transformation of external events into neural activity;
•Processing of sensory information; we believe that the end result is a useful representation in terms of the external objects that produced the sensations;
•Organisms use the representation of the world in order to act on it, optimizing rewards and minimizing punishments;
•Emotion is often the driving force behind motivation, positive or negative.
Our Neuronal Processing Mechanism
EEG, Sensors, Inputs
MEME dataset scales• Spatial = S (Structure) • S = Brain Region Area (cm) = # Sensors EEG
selected• Energy = E (Efficiency)• E = reflects the summation of the synchronous
activity of thousands or millions of neurons that have similar spatial orientation = microVolts (mV) [2..100mV]
• Time = T (Function) • T = seconds (sec); • Analysis type: continuous || steady-state
• S+E+T = inputs variables to build, run and validate regression and classification models (machine learning)

mind experiences
model experimenter
• Signal acquisition from EEG sensors (live or recorded in EDF format) with “events marks” (M) regarding the parameters of the experience configured or manually sent by the user;
• Run machine learning models using the inputs (S+E+T) and predicting the output (M) ;
• Using an event manager, any time that the model predict inputs values associated with a specific mark associated with the experience, will be triggered a command to could interact with other systems;
• Implementation of OCC Model.
•build/train/validate machine learning models
• Nearest neighbor classifiers, linear classifiers, nonlinear Bayesian classifiers, neural networks and some combination of classifiers (soon, markov models);
•design/edit/play mind experience•setup/validate/run models
experimenter; •add manually marks at recorded
experiences to measure stimulus from other senses (e.g. taste, external events).

crowdsourced science is more than expediting data collection and analysis–it helps communicate science with the world”
