Hank, a war veteran, suffers from anomia after damage to his left hemisphere and remembers and recognizes objects, but is not able to name them. This is an example of that object recognition is not the same as the naming of objects. Also, Hank’s example shows that producing speech is not the same as understanding speech.Language is very typical for humans and is the key thing that distinguishes humans from other species. Language can be seen as ‘natural’ because it originates from the brain. In other words: it is produced by the brain. It can also be written, spoken or portrayed and it can be used to communicate information about the past, present or future between people and therefore it is regarded as social.The research in language started in 1960. Patients with language issues were examined with the goal to develop a better picture of the brain. Psycholinguistics focused mainly on the cognitive aspects of language. Later a combination of these types of research developed, named cognitive neurosciences. A huge part of language processing happens in the left hemisphere mainly around the Sylvian fissure. Also Wernicke’s area and Broca’s area are located in the left hemisphere. All the language areas and the connections between the areas are called the left sylvian language network. Some areas in the right hemisphere also play a role in language processing, such as processing the prosody of language and metaphors. And lastly, motor skills and timing are also important for efficient communcation. So there are also areas that control motor skills. Aphasia often develops after lesions and has a big impact on understanding and producing language. It can also lead to problems in speech because of reduced muscle control, which is called dysarthria. Apraxia is an acquired...
