Document Summary
Hypothetical group of neurons that become connected because they receive the same sensory input, these are the basis of perception, memory, and thought. Thinking in mammalian brain, is located in the cortex. Neocortex outside the primary sensory and motor cortex that produces cognition. One of the key differences between association cortex and the primary sensory and motor cortices is the pattern of connections. The association cortex receives highly processed information about the external and internal world (more than the primary cortexes receive) Prefrontal association cortex: takes up a lot of space in the brain. Frontal association cortex: damage can lead to focusing excessively on external stimuli and difficulty shifting attention. Parietal association cortex: damage can produce contralateral neglect (ignoring a part of the body on the opposite side of the brain injury) Experiment: in order to test for this injury people are asked to draw a clock.
