Document Summary

The physical structure of the brain allows it to function in certain ways, just as the typical structure of a building allows it to function in certain ways. Mental contents: comprise knowledge, beliefs (including ideas, explanations, and expectations), desires (such as hopes, goals, and needs), and feelings (such as fears, guilts, and attractions). Mental processes: sets of operations (such as shifting the focus of attention over a scene) that work together to carry out a function (such as perception, language, or memory). Note: most of the neurons in the brain are interneurons. Brain circuits: sets of neurons that work together to receive input, operate it in some way, and produce specific output. Structure of a neuron: the ins and outs. Cell body: the central part of the neuron. Cell membrane: the skin that surrounds the cell. The long, cable-like structure extending from the cell body, along which signals travel to other neurons, muscles, or bodily organs.
