Document Summary
Just as the cognitive revolution was beginning, something else was happening that would have a huge impact on our understanding of the mind. Early conceptions of neurons: looking at the interior of the brain with the unaided eye gives no indication that it is made up of billions of smaller units. The signals that travel in neurons: determining the exact nature of these signals had to await the development of electronic amplifiers that were powerful enough to make the extremely small electrical signals generated by the neuron visible. The story of neural representation and cognition: a preview. Geometrical objects) then send signals to even higher areas, combining and interacting further and creating neurons that respond to even more complex stimuli (ex. Faces: this progression is called hierarchical processing. In the early 1800s, an accepted principle of brain function was cortical equipotentiality- the idea that the brain operated as an indivisible whole as opposed to specialized areas.
