which part of the human body has no pain receptors, even if it’s pierced?

The classic answer to this question is: the brain itself has no pain receptors, so the brain tissue can be pierced without feeling pain.

Quick Scoop

• The surface of the brain (the neural tissue) does not contain pain receptors (nociceptors), which is why patients can sometimes be awake during certain brain surgeries without feeling cutting or probing of the brain itself.

• Pain during head injuries or neurosurgery usually comes from structures around the brain that do have pain receptors, such as the scalp, skull, meninges (like the dura mater), and blood vessels.

• This is why quiz-style posts and forum threads often give “the brain” as the answer to “which part of the human body has no pain receptors, even if it’s pierced?”

In everyday riddle and forum discussions, “the brain” is treated as the correct one-line answer, even though the tissues surrounding it are very sensitive to pain.

A tiny nuance

• Other body parts (like hair and nails) also lack pain receptors themselves, but the skin and tissue they grow from are full of them, so pulling or cutting too far down still hurts.

• For piercing-related contexts, professional body piercers do not pierce the brain; the phrase is used as a fun fact rather than an actual piercing location.

TL;DR: The riddle-style answer is the brain , because brain tissue has no pain receptors and can be pierced without directly causing pain, even though nearby structures can hurt a lot.
