Three models of human language

Area of Science:

• Neurobiology
• Cognitive Science
• Linguistics

Background:

• Contemporary neurobiology recognizes three primary models of human language processing.
• These models include the Wernicke-Broca model, Ojemann's electrical stimulation mapping model, and Chomsky's linguistic model.

Purpose of the Study:

• To delineate and compare the fundamental concepts of three distinct models of human language processing.
• To highlight the differing conceptions of brain language organization presented by these models.

Main Methods:

• Review of established neurobiological and linguistic theories.
• Analysis of findings from lesion studies (Wernicke-Broca model).
• Examination of data from direct cortical electrical stimulation mapping (Ojemann's model).
• Consideration of principles from linguistic theory (Chomsky's model).

Main Results:

• The Wernicke-Broca model posits a posterior-sensory, anterior-motor pathway for language.
• Ojemann's model suggests a more modular organization of language functions in the cerebral cortex.
• The linguistic model frames language as an abstract, hierarchical mental function.

Conclusions:

• Significant divergence exists between the Wernicke-Broca and Ojemann's models regarding brain language localization.
• The linguistic model offers a distinct, cognitive perspective on language processing.
• Understanding these diverse models is crucial for advancing research in neurolinguistics.
