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.

Test your knowledge on the regions of Brodmann Area 47 and function of the Frontal Lobe, including the Primary Motor Area, Pre-motor Area, and Frontal Eye Field. Identify the functions and consequences of lesions in these areas.
