The nondominant hemisphere contains areas of cortex analogous to Broca’s and Wernicke’s areas, but for the production and comprehension of prosody, which is the emotional content of speech, or inflection. There is more variability in this anatomy than for the language cortices. Aprosodia refers to a loss of prosody. Expressive aprosodia may occur with anterior lesions, receptive aprosodia may occur with posterior lesions, and mixed aprosodia may occur with larger lesions involving anterior and posterior areas.
