What name does Dr. House use when he enters a psychiatric hospital in House M.D.?

Dr. House uses his real name, Gregory House, when he enters Mayfield Psychiatric Hospital in House M.D.

At the end of season five, House voluntarily commits himself to Mayfield after hallucinations and worsening dependence on Vicodin reveal that he needs psychiatric treatment. The season-six premiere, “Broken,” follows his treatment under Dr. Darryl Nolan. House initially resists the program, but the story examines his addiction, pain, relationships, and difficulty accepting responsibility.

Mayfield is a fictional psychiatric hospital. The setting changes the series’ usual diagnostic format: instead of solving rare physical illnesses at Princeton-Plainsboro, House becomes a patient and must participate in therapy and group treatment. Andre Braugher plays Nolan, the psychiatrist who supervises his recovery.

The name is occasionally confused with a pseudonym because House often lies or uses aliases during investigations. In the Mayfield storyline, however, the character is admitted as Gregory House rather than under a fabricated identity.
