Open Courses @ MIT?

Here are links to a couple of Health Science & Technology graduate courses at MIT:

• HST 723: Neural Coding and Perception of Sound
• HST 725: Music Perception and Cognition

Now, tell me that's not the coolest thing you ever heard. The lecture notes, reading lists, and syllabi are posted for all kinds of courses. One of the texts is:

Helmholtz, H. L. F. On the Sensations of Tone. Translated by A. J. Ellis. New York, NY: Dover, 1954. ISBN: 9780486607535.

I recall reading that Wendy Carlos was a fan of this text as a young composer.
