The auditory system, like the other sensory systems, must perform four tasks:

2
00:00:12.000 --> 00:00:23.000
First, pick up stimulus energy from the world around us. This energy is in the form of sound waves.

3
00:00:23.000 --> 00:00:31.000
Second, change that energy into a pattern of neural impulses.

4
00:00:31.000 --> 00:00:38.000
Third, carry those impulses to the proper locations in the brain.

5
00:00:38.000 --> 00:00:50.000
Finally, process the information contained in the pattern of impulses so that the stimulus can be identified.

6
00:00:50.000 --> 00:01:04.000
In the auditory system, the first two of these tasks are performed by the complex structure we call the ear.
