Sensorium \Sen*so"ri*um\, n.; pl. E. {Sensoriums}, L.
   {Sensoria}. [L., fr. sentire, sensum, to discern or perceive
   by the senses.] (Physiol.)
   The seat of sensation; the nervous center or centers to which
   impressions from the external world must be conveyed before
   they can be perceived; the place where external impressions
   are localized, and transformed into sensations, prior to
   being reflected to other parts of the organism; hence, the
   whole nervous system, when animated, so far as it is
   susceptible of common or special sensations.
