Study Notes
Brain Structure and Function
- The brain can be divided into two halves, with one half being the mirror image of the other.
- The two halves are physically identical but perform different functions for most people.
Contralateral Control
- The left side of the brain controls the right side of the body, and vice versa.
- This applies to most senses, including vision, motor control, and touch.
- The only exception is smell, where the two cerebral hemispheres communicate with the same side of the body.
Dominant Hemisphere
- Most people have a dominant hemisphere, which is typically the left hemisphere for right-handed individuals.
- The dominant hemisphere is responsible for language, including speech production (Broca's area) and comprehension (Wernicke's area).
- The dominant hemisphere is also involved in analytical tasks, such as logic and math skills.
Nondominant Hemisphere
- The nondominant hemisphere, typically the right hemisphere, plays a less prominent role in language but is involved in other tasks.
- It is responsible for understanding the emotional tone of language and recognizing emotions in others.
- Research suggests that the nondominant hemisphere may be involved in creativity, music, spatial processing, and big-picture thinking.
Brain Communication
- The two cerebral hemispheres communicate with each other through a large band of fibers called the corpus callosum.
- Without the corpus callosum, the two sides of the brain cannot communicate, leading to interesting consequences.
Brain Structure and Function
- The brain is divided into two identical halves that perform different functions in most individuals.
Contralateral Control
- The brain uses contralateral control, where the left side controls the right side of the body, and vice versa.
- This control applies to various senses, including vision, motor control, and touch.
- Smell is the only exception, where the two cerebral hemispheres communicate with the same side of the body.
Dominant Hemisphere
- Most people have a dominant hemisphere, typically the left hemisphere in right-handed individuals.
- The dominant hemisphere is responsible for language processing, including speech production (Broca's area) and comprehension (Wernicke's area).
- It is also involved in analytical tasks, such as logic and math skills.
Nondominant Hemisphere
- The nondominant hemisphere, typically the right hemisphere, plays a secondary role in language processing.
- It is responsible for understanding emotional tone and recognizing emotions in others.
- Research suggests the nondominant hemisphere is involved in creativity, music, spatial processing, and big-picture thinking.
