Where is language primarily housed in most adults?
The perisylvian area of the left hemispheric cortex of the cerebrum.
How is the Cerebrum divided?
It is divided into right and left hemispheres that are connected by the corpus callosum.
What is the corpus callosum?
It is what connects the right and left hemispheres of the cerebrum.
Which hemisphere shows more neural activity during word problems?
The left hemisphere.
What happens when the corpus callosum is severed?
Stimuli coming from the left ear or eye cannot reach the language center.
What is Aphasia?
Language loss due physical injury to the perisylvian area of the left hemispheric cortex.

- Difficulty speaking
- Speech consists of isolated content words
