Study Notes
Frontal Lobe
- BA 4: Primary Motor Area, located in Pre-central Gyrus, responsible for execution of motor functions; lesions lead to flaccidity
- BA 6: Pre-motor Area, responsible for smooth motor movements, modulation of movement initiation, and coordination of movements; lesions lead to spasticity, akinesia, and incoordination
- BA 8: Frontal Eye Field, responsible for conjugate eye movements; lesions lead to frontal gaze palsy
- BA 9, 10, 11, 12: Pre-Frontal Areas, also known as the "Seat of Intelligence", responsible for personality and behavior
- BA 44, 45: Broca's Area, responsible for motor speech; lesions lead to Broca's aphasia, characterized by impaired fluency, naming, repetition, and writing ability, while reading and auditory comprehension are spared
Parietal Lobe
- BA 3, 1, 2: Primary Somesthetic Area, located in Post-central Gyrus, responsible for interpreting pain and temperature sensations; lesions lead to anesthesia
- BA 5, 7: Secondary Sensory Area, responsible for interpreting sensations except pain and temperature, including touch, proprioception, kinesthesia, barognosis, stereognosis, vibration, and 2-point discrimination
- BA 39: Angular Gyrus, responsible for left-right orientation, mathematical ability, reading, writing, and naming; lesions lead to anomia (anomic aphasia) and Gerstmann syndrome (left-right disorientation)
- BA 40: Supramarginal Gyrus, assists in language processing and comprehension; lesions lead to ideomotor apraxia
- BA 43: Primary Gustatory Area, responsible for taste; lesions lead to aguesia
Occipital Lobe
- BA 17: Primary Visual Area, located in Striate Complex, responsible for sense of light; lesions lead to cortical blindness or congenital homonymous hemianopsia
- BA 18, 19: Secondary Visual Area, responsible for interpreting images perceived by BA 17; lesions lead to visual agnosia, prosopagnosia, color agnosia, and Balint's syndrome
Temporal Lobe
- BA 41, 42: Primary Auditory Area, located in Heschl's Gyrus, responsible for hearing; lesions lead to cortical deafness or congenital deafness
- BA 22: Right Area is the Auditory Association Area, and Left Area is Wernicke's Area, responsible for auditory association
