Practice question · True or false
In a healthy person with an intact corpus callosum, an object seen only in the left visual field can still be named aloud, because the hemispheres share the information.
Hints
- What is different here from the split-brain case?
- With the callosum intact, the right hemisphere CAN pass the information to the left speech hemisphere.
Show the answer
True
Why
True. With the callosum intact, information reaching the right hemisphere is shared with the left speech hemisphere, so the object can be named - unlike the split-brain case. This isolates the corpus callosum as the structure that makes naming possible.
