What part of the CNS sorts almost all of the ascending sensory information?

The part of the central nervous system (CNS) that sorts almost all ascending sensory information is the thalamus. It acts as a relay station, processing and transmitting sensory data from the body to the appropriate areas of the cerebral cortex for further interpretation. Exceptions include the sense of smell, which bypasses the thalamus and goes directly to the olfactory bulb. Thus, the thalamus plays a crucial role in sensory perception and integration.
