When the brain is locating the physical self in its environment, the sensory cortex is activated.

"What's the headwind that's blowing back that sensory information and keeping it in the sensory cortex?"

Sensory stimuli from the eyes, ears, and such are converted to electrical signals and then transmitted to the relevant parts of the sensory cortex that process these inputs and induce perception.

In 2016, Nathan Copeland, who was paralyzed from the chest down in a car accident, not only fist-bumped President Barack Obama with a robotic hand, he also experienced the tactile sensation of the bump in his own hand as the prosthesis sent signals back to electrodes in his brain, stimulating his sensory cortex.

All of this information is initially processed in the brain’s sensory cortex.
