Broca

The frontal cortex consists of three main structures (i) motoric regions (including the Broca area and ocular areas), (ii) the prefrontal cortex, and (iii) the orbital cortex. The prefrontal cortex is associated with attention, arousal, and expectation, the orbital cortex with motivation.

A patient with a lesion in Wernicke s area is unable to understand any spoken or visual information. Furthermore, the patient s speech, while fluent, is unintelligible because of frequent errors in the choice of words. This condition is known as receptive aphasia. On the other hand, a patient with a lesion in Broca s area is able to understand spoken and written language but is unable to express his response in a normal manner. Speech in this patient is nonfluent and requires great effort because he cannot establish the proper motor command to articulate the desired words. This condition is known as expressive aphasia.
