Sensory systems code for four aspects of a stimulus; type (modality), intensity, location, and duration.
Modality
There are many stimulus modalities; temperature, taste, sound, pressure. The type of sensory receptor activated by a stimulus plays the primary role in coding the stimulus modality.
The organ of Corti is the organ in the inner ear of mammals that contains the auditory sensory cells, the so-called hair cells.
The organ was named after the Italian anatomist Marquis Alfonso Giacomo Gaspare Corti (1822-1876), who conducted microscopic research of the mammalian auditory system from 1849 to 1851 at the Koelliker laboratory in Würzburg (Germany).
In 1851 he was the first to describe the core sensoryorgan in the mammalian cochlea, the organ of Corti.
