PSYB65H3 Chapter Notes - Chapter 16: Prefrontal Cortex, Frontal Lobe, Orbitofrontal Cortex
Document Summary
Chapter 16: the frontal lobes (pgs430, 434) thus derive their information from the object-recognition or motor streams of sensory processing. Recall that both streams project to the prefrontal cortex, although to different places (see figure 16. 3), which suggests temporal memory for both motor and object information, although the memory will be localized in different places in the frontal cortex. The dorsolateral areas are especially engaged in the selection of behavior based on temporal memory. People whose temporal memory is defective become dependent on environmental cues to determine their behavior. That is, behavior is not under the control of internalized knowledge but is controlled directly by external cues. One effect of this condition is that people with frontal-lobe injuries have difficulty inhibiting behavior directed to external stimuli. In our dinner-party example, frontal-lobe patients would enter a shoe store or chat with friends as they responded to environmental cues that they encountered.
