Broca's area vs. Wernicke's area
At first, it may be difficult to differentiate Broca's area from Wernicke's area as they both have to do with speech, but there are a few differences which you can focus on remembering in order to help you better understand the two.
Let's start with Broca's area, which is located in the frontal lobe. Broca's area is the motor speech area and it helps in movements required to produce speech. When there is an issue in this area, a patient can understand the speech of others, but can't produce any speech him or her self. This is called Broca's aphasia. Wernicke's area, which is located in the parietal and temporal lobe, is the sensory area. It helps in understanding speech and using the correct words to express our thoughts. When there is an issue in this area, a patient may be able to produce speech, but cannot understand the speech of others. This is called Wernicke's aphasia. I'll link you to a few information videos and articles that will help you further understand these concepts.
