Wernicke’s area – Knowledge and References

Wernicke's area

Wernicke's area is a region located in the posterior part of the temporal lobe, specifically the left temporal gyrus, that is responsible for the association and interpretation of information in language processing and comprehension. Damage to this area can result in receptive aphasia, where the individual is unable to understand spoken language.From: Biomedical Engineering Fundamentals [2019], A Functional BCI Model by the P2731 working group: Physiology [2021], Epilepsy [2019], Introduction to Non-Invasive EEG-Based Brain–Computer Interfaces for Assistive Technologies [2020]

The language processing, comprehension, and speech production occur in Broca’s area, whereas the association and interpretation of information occur in Wernicke’s area (Figure 1.5a), which plays a very important role during the chaining of the discourse. This area allows us to understand what others say and also provides the ability to organize the words in a way syntactically correct. Broca’s area is located in the left hemisphere in 95% of persons [2].

Diagrams of cerebral anatomy associate specific structures with function, but, when considering a phrase such as visual cortex or speech center, the word ‘primary’ is an important qualifier. The brain can be mapped into regions that differ in their cellular organization, and these regions often correspond to meaningful functions. For instance, speech production and comprehension are, respectively, related to Broca’s area, which is located in the inferior frontal gyrus [25] and Wernicke’s area, which centers on the posterior end of the left temporal gyrus. Attempts to map cerebral regions and to identify regions with functions began in the early 20th century. No consensus on the number of cerebral regions exists, and most researchers admit more work needs to be done, but convincing arguments are made for at least 180 functional regions per hemisphere [14].
