The speaker is Holden Caulfield, the narrator of the cult novel "The Catcher in the Rye", by recluse writer J.D. Salinger. Holden is a teenager who escapes a boarding school in order to spend a few days in New York, where he interacts with strangers and experiences new things.
Meaning and context: When Holden says he has Jane Gallagher on the brain again, he means he cannot stop thinking about her.
