Map of You

"Researchers are currently working on a map of the human brain. It may be the most complex map ever created. Billions of neurons making trillions of connections. At first glance, they seem completely random. But there's nothing random about them. All these connections have to happen in a specific pattern. It is designed for a function. These connections determine everything about us: what we love, what we hate, what we say, what we do. We're just starting to learn the extinct of the brain's connections. How far they reach, how deep they go. But we know that every connection matters. Every connection is crucial and when one is broken, it usually means some damage has been done. This system of connections compels us to act and choose and behave. Sometimes humanly against our own will, but it is not random at all. It is the map of who we are. We work to understand ourselves. Solve the puzzle. How all the connections work, and all the pieces fit."

- Derek Shepherd

Full Summary
Derek’s voiceover talks about brain mapping. At the dreamhouse, Meredith and Derek are getting ready for their day. Derek’s voiceover talks about the interactions in your brain being random as he watches Zola scribble. He takes a crayon and sketches his own drawing.

At the hospital, Callie and Derek take out the new equipment and check it out. Derek’s voiceover talks about how your brain controls everything.

Derek operates to insert a chip into a patient’s brain.

The patient, Mickey, sits in his wheelchair, facing a computer monitor. Derek tells him to open his hand and the hand on the monitor opens. The doctors in the room clap. Derek says to close it. He does. Derek explains the brain activity they’re seeing on the monitor. Mickey says he’ll be good at Tetris again. He tells them to check out the monitor and he makes the hand hold up only the thumb and pinky. They clap again.

Mickey asks where Dr. Torres is and why she’s missing this debut. Derek whispers to Shane to text her again.
