Document Summary
Logic limits: you cant compute something a universal machine cant compute, you cant prove something that cant be proved. Sparsity: for how many distinct objects will a neuron fire, num objects per neuron = sparsity * num objects, num neurons per object= sparsity * num neurons fmri, measures changes of oxygen lvls in blood. Ann: synaptic strength-neural net connection strength, computer- digital (0 1) and analog(electrons, neurons- digital (spikes) and analog(amount of neurotransmitter) Turning test: sufficient, fail the test doesn"t mean not intelligent- fail on purpose, speak different language. How do you tie the image with the sound of something happening. Processing something without being conscious about it. H^2 = vg / (vg + ve) denominator- vphenotype. Your body has a physiological reaction- that"s the somatic marker. Tells body how to react- behavioral tendency. Bodily reaction is a story of whats going on and prepares you for some action. Ex: gets you ready to run when theres danger.
