Study Notes
Brain Areas and Functions
- Broca's area is specialized for speech.
- Wernicke's area is associated with fluent but incoherent speech.
- The occipital lobe is responsible for vision, and damage to it can result in blindness.
Cognitive Disorders
- Prosopagnosia is characterized by an inability to recognize faces.
- The study by Hubel and Wiesel showed that damage to the occipital lobe could result in blindness.
Brain Function Research
- Demonstrating a double dissociation is important to establish the specificity of brain areas to specific cognitive functions.
- Doris Tsao and coworkers found that single neurons in the macaque temporal lobe respond to specific faces in their single-neuron recording research.
- Functional magnetic resonance imaging (fMRI) measures changes in blood flow and oxygenation to detect brain activity.
Brain Function and Organization
- The term "distributed processing" describes the phenomenon where specific cognitive functions activate many areas of the brain.
- The parahippocampal place area (PPA) plays a key role in the brain's spatial navigation and recognition of scenes.

Description
Test your knowledge on the basic principles of brain organization, focusing on how specific functions are served by distinct areas of the brain. Explore the field of cognitive neuropsychology by studying the behavior of individuals with brain damage, such as patients affected by stroke. Learn about famous cases like patient 'Tan' and the discovery of Broca's area in the left frontal lobe.
