Key Points
- Brain organs will not feel any pain on being pricked by a needle.
- The brain is a painless organ.
- So pricking or even removing a part of the brain, while a person is conscious, does not cause any pain.
- Operating brain in a conscious state is a common procedure which is known as “awake craniotomy”.
- A cover around the brain is a painful structure. Pricking it can cause severe pain.
- There are no pain nor tactile (touch) receptors of any type in the brain itself.
- So, a needle or even more invasive brain surgery is not associated with any “sensation” of the brain being touched in the patient.
- Hence, option 2 is correct.
