Study Notes
Determining Functions of Cortical Areas
- The main method used to determine the functions of specific cortical areas in human beings is through electrical stimulation of the cortex in awake patients.
Recording Thoughts and Movements
- During electrical stimulation of the cortex, thoughts evoked are recorded through patient reports.
- Patients may report experiencing movements due to electrical stimulation, providing evidence of cortical area function.
Cortical Areas and Functions
Figure 58-4
- Based on a synthesis of information from various sources, Figure 58-4 includes the parieto-occipitotemporal association area, facial recognition areas, and other cortical areas.
Parieto-Occipitotemporal Association Area
- Analyzes spatial coordinates of the body, visual, and auditory surroundings.
- Provides continuous analysis of spatial coordinates in the hands, feet, and arms.
Facial Recognition Areas
- Located in the parieto-occipitotemporal cortex, these areas compute and recognize facial features.
- They are closely linked to the limbic system, emphasizing their importance in emotional and social processing.
- The text highlights the significance of the facial recognition area, as damage to this region can lead to difficulties in recognizing faces.
Brain Damage and Condition
- In individuals with certain conditions, the temporal and parietal lobes of the brain are extensively damaged.
