Answer:
Cerebral cortex
Step-by-step explanation:
- Cerebral cortex forms the outer layer of cerebrum of brain. It is involved in perception, memory formation, consciousness etc.
- Many cerebral cortical structures like motor cortex, cingulate cortex and insular cortex form a network which is primarily involved in perception and modulation of pain.
- Neurotransmitters like GABA, dopamine and glutamate also impact the pain response via cerebral cortex.
- Hence, the patient is displaying pain response due to the activity of cerebral cortex.
