ABSTRACT

In the classical explanation of the central language mechanism, the left cerebral hemisphere contains the neural structures that are responsible for processing words and sentences. To this day, the left-hemisphere explanation proposed by Karl Wernicke in 1874 remains the most accepted model of the central language-processing mechanism (Buckingham, 1982). However, converging neurobehavioral evidence has precipitated modification of the classical model by demonstrating that neuroanatomic structures in the left-hemisphere area do not function in isolation from other parts of the brain.
