Document Summary
Brain: an metabolically expensive organ 100 billion neurons that can make up to 10000 connections, neurons are communication devices. Inter neuron: simple behaviour: knee jerk reflex. Hammer strike on patellar ligament will cause your leg to kick forward. This is very useful b/c brain does not have to deal with this. Heuristics and prior knowledge: you never experience stimuli in isolation, you always experience it in by interaction with previous experiences, a bat and a ball together cost . 10 the bat costs more than the ball. Prior knowledge has probably shaped how you approached this problem: visual top down processing. All your prior knowledge that can act as a filter to how you interpret stimuli. Ex. segmentation problem many sound waves reaching your ears but you can still understand words and you know. How to wreck a nice speech: the context filters the exact same audio stimulus into what mean important for you.
