Study Notes
Brain Development
- The brain continues to develop after birth, with subtle changes happening throughout life
- Different regions of the cerebral cortex have specialized functions like analyzing visual, auditory information, and controlling muscle movement
- Genetic programming and experience play a role in brain development
- Experience influences the development of neural connections, for example, stereoscopic vision develops during a critical period in early childhood
The Motor Association Cortex
- The motor association cortex, or premotor cortex, controls the primary motor cortex, which directly controls behavior
- The prefrontal cortex, located rostral to the motor association cortex, is involved in planning and strategy
Cerebral Hemispheres
- The left hemisphere analyzes information, excels at recognizing serial events, and controls sequences of behavior
- The right hemisphere synthesizes information, excels at perceiving things as a whole, and is involved in activities like drawing, reading maps, and constructing complex objects
The Occipital Lobe
- Located at the back of the brain
- Responsible for visual processing
The Primary Sensory Regions
- Each primary sensory area sends information to the sensory association cortex, which analyzes and stores information
- The sensory association cortex closest to the primary area receives information from only one sensory system
- The visual association cortex analyzes visual information and stores visual memories
- Damage to the somatosensory association cortex can lead to difficulties perceiving shapes, naming body parts, or navigating
- Damage to the visual association cortex can lead to difficulty recognizing objects
- Damage to the auditory association cortex can cause problems with speech perception or production
- Damage to the area where the somatosensory, visual, and auditory functions overlap can lead to reading and writing difficulties
