3 · Analysis · Hard · Brain Lateralization and Split-Brain
A patient with intractable epilepsy undergoes a corpus callosotomy (severing of the corpus callosum). In a split-brain experiment using a tachistoscope, words are briefly flashed to either her left or right visual field, and she is asked to verbally name what she sees. Identify which visual field presentation will prevent her from naming the word, and explain the neuroanatomical pathway that causes this specific deficit.
Write your answer, then tap Show model answer. The model answer and marking points will appear here.
Compare with your answer.
Model answer. Presentation to the left visual field will cause the patient difficulty when asked to name the flashed word.
Explanation: Visual stimuli presented to the left visual field are processed exclusively by the right cerebral hemisphere. In most individuals, speech production is localized in the left hemisphere. Because the corpus callosum has been severed, information cannot cross from the right hemisphere to the left hemisphere. Consequently, while the right hemisphere perceives the word, the verbal left hemisphere cannot report it aloud.
