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.
