QuestionChoice
Incorrect as this is not Broca's area. The cingulate gyrus is a component of the limbic system and is involved in behaviour regulation, processing emotions and regulating autonomic motor function.

This patient is presenting with Broca's aphasia (non-fluent or expressive aphasia). Symptoms of Broca's aphasia include very poor or absent spontaneous speech with a difficulty in forming complete sentences. There is typically a loss of normal grammatical structure, trouble writing sentences and more difficulty using verbs than nouns. However, understanding is not affected so the patients can still understand others' speech. Broca's aphasia results from damage to the Broca's area which is located in the dominant hemisphere of the frontal lobe in the inferior frontal gyrus (on the left side in a right-handed individual or the right side in a left-handed individual). Therefore, the inferior frontal gyrus is correct.

Inferior frontal gyrus
QuestionChoice
Incorrect as this is not Broca's area. The lingual gyrus is involved in processing vision and is located in the occipitotemporal region.

Lingual gyrus
QuestionChoice
Incorrect as this is not Broca's area. The superior temporal gyrus is the location of the Wernicke's area. Damage to this area leads to Wernicke's (fluent or receptive aphasia) aphasia which results in difficulty understanding others' speech or difficulty processing the meaning of words. Patient's with Wernicke's aphasia can articulate their words normally but speak in a jumbled "word salad" i.e. when speaking they string words together that don't make sense in a sentence. They are typically unaware of the mistakes in their speech.

QuestionChoice
Incorrect as this is not Broca's area. The superior parietal lobule is involved in attention and visuospatial perception.

A 63-year-old man presents to A+E with speech problems. He is struggling to talk fluently and can only speak in short, disjointed sentences with continuous stuttering. However, he can understand what others say to him. An MRI was performed which showed a lesion in his left cerebral hemisphere.

In what area of the brain is the lesion most likely located?
