    Study Notes

    Lesions and Associated Impairments

    • Damage to BA 39, the Angular Gyrus, can lead to agraphia (writing impairment) and alexia (reading impairment).
    • Lesions in BA 17, the Primary Visual Area, may result in visual field deficits, such as homonymous hemianopia.
    • Damage to BA 22 on the left side is likely to cause Wernicke's Aphasia, characterized by fluent but nonsensical speech.
    • Lesions in BA 41 and 42, the Primary Auditory Area, can lead to auditory agnosia, affecting sound recognition despite normal hearing.
    • A lesion in BA 43, the Primary Gustatory Area, may result in ageusia, or loss of taste sensation.
    • Cognitive deficits from lesions in BA 18 and 19, which are involved in visual processing, can include visual agnosia or difficulty in recognizing objects.

    Key Brodmann Areas and Functions

    • BA 4 is identified as the Primary Motor Area, responsible for voluntary motor control.
    • BA 6 has a main function in planning and coordinating voluntary movements.
    • Lesions in BA 4 can induce spasticity, akinesia (difficulty in initiating movements), and incoordination.
    • The prefrontal cortex, often referred to as the 'Seat of Intelligence,' plays a critical role in cognitive functions such as reasoning and planning.
    • Broca's Aphasia is associated with lesions in BA 44 and BA 45.
    • BA 3, 1, and 2 in the parietal lobe are primarily responsible for processing sensory information related to touch, temperature, and proprioception.
