Document Summary
Many of the brain structures required for vision are also implicated for imagery. Vision relies heavily on tissue in occipital cortex: activity levels are also high in these areas when ps are visualizing a stimulus. Also: there are specific areas on the oc that respond to different details of a visual scene (v1, v2, etc: these same brain areas are active in this particular way when people imagine stimuli. Similarly, brain areas that are active during perception of faces are also highly activated when people are imagining faces. Evidence shows two types of imagery to exist: visual and spatial. What type of imagery we use depends on the task at hand. Ex: colors: you need visual imagery because you need to think about what things look like. The choice between what type of imagery people use influenced by their ability levels: some people may be poor visualizers but good spatializers and vice versa.
