In House M.D., what fictional psychiatric hospital treats Dr. House during season six?

Mayfield Psychiatric Hospital is the fictional facility where Dr. House receives inpatient treatment during season six of House M.D.

House enters Mayfield after the events of season five, when his dependence on Vicodin and worsening hallucinations force him to confront his health. The two-part season-six premiere, “Broken,” follows his admission, treatment, relationships with other patients, and eventual attempt to return to ordinary life.

Mayfield is a fictional institution created for the series, not a real hospital in New Jersey. The storyline is important because it temporarily shifts the setting away from Princeton-Plainsboro and directly explores House's addiction and psychiatric care. The facility should not be confused with the show's regular teaching hospital.
