Johnston's organ

[BPREGG31 at MAINE.MAINE.EDU]

I am looking for information about neural processing of auditory information
in Drosophila.  I understand that the arista at the end of the antenna vibrate
in response to sound waves, and this information is somehow transfered to the
Johnston's organ in the second antennal segment.  Is this correct?  If you
know of any references, or have an additional understanding of the system, I'd
appreciate the info.
Gratefully,
Becky Talyn
