What are the motor areas and their Brodmann numbers?
- Primary motor cortex (4)
- Premotor cortex (6)
- Frontal eye field (8)
- Broca’s area (44, 45)
What are the sensory areas and their Brodmann numbers?
- primary somatosensory cortex (3, 1, 2)
- Visual areas (17)
- Wernicke’s area (22)
- Olfactory cortex (28)
- Auditory areas (42)
- Gustatory cortex (43)
What are the 3 types of functional areas?
Motor areas (control voluntary movement)
Sensory areas (conscious awareness of sensation)
Association areas (integrate diverse information)
What does the primary motor cortex do
conscious control of precise, skilled, voluntary movements
What does the premotor cortex do
- controls learned, repetitious, patterned motor skills
- coordinates simultaneous or sequential actions
- involved in planning of movements that depend on sensory feedback
What does Broca’s area do
directs muscles of the tongue in speech and is active as one prepares to speak
What does the frontal eye field do
controls voluntary eye movements
What does the primary somatosensory cortex do
receives sensory info from the skin, skeletal muscles, joints, and is capable of spatial discrimination
What do the visual areas do
receives visual info from the retinas
What does Wernicke’s area do?
comprehends spoken language and recognizes familiar sounds and words (communicates with Broca’s area when repeating back what was just said/heard)
What do the auditory areas do?
interprets info from inner ear as pitch, loudness, and location
What does the olfactory cortex do
conscious awareness of odors
What does the gustatory cortex do
involved in the perception of taste
