Abstract:
To be a neurologist, training in cognitive/behavioral neuroscience is essential. In this review article, the author tries to emphasize the localization relationship between focal brain lesions and language dysfunction, by discussing from split-brain syndromes, hemispheric asymmetry, to pure word dumbness, pure word deafness (verbal auditory agnosia), pure agraphia, and pure word blindness (pure alexia; visual word agnosia), and finally to aphasia and aprosodia in general. Hopefully, after getting familiar with all the terms, the readers will feel free exploring language disturbances and behavioral neurology for their own interests.

Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
