4 major lobes
frontal
parietal
temporal
occipital
function of frontal lobe
cognition, motor activity, spoken language
- includes Broca’s area (language expression)
Function of parietal lobe
processes body sense
Function of temporal lobe
receives auditory information
- include Wernicke’s area (language comprehension)
Insular lobe
subserves planning and organization of speech (some consider insular par of temporal)
Thalamus
relay station for sensory information
