Sensorium refers to the entirety of the brain regions involved in receiving, processing, and interpreting sensory information. It is considered the center of sensation, where impressions from the external environment are transmitted and understood. Additionally, the term encompasses the body's complete sensory system. In medical contexts, "sensorium" may be used to describe cognitive and mental functions. For instance, "A 77-year-old woman was admitted to the hospital with a week-long history of altered sensorium" (New Engl J Med 343: 1933, 2000). The term "sensorium" has its roots in the Latin word "sensus," meaning "the capacity to perceive." Although the plural form of "sensorium" is seldom used, options include "sensoriums" or "sensoria" if necessary.
