The human nervous system allows us to experience pain. When our body detects potential harm or injury, specialized nerve receptors called nociceptors send signals to the brain, which interprets these signals as pain.
There are no pain receptors in your brain, so it feels no pain.
the iris finds and detects images and sends them to the brain
No. Pain is merely a signal sent to the brain and the brain registers the pain. Bacteria lacks a brain, therefore can feel no pain.
The brain itself is what makes you feel pain. However, the brain itself does not have pain receptors itself. This is why patients can be conscious during neurosurgeries.
