Hi Matt and others,

Our job is not to find mathematical equations that fit our thoughts. Our job 
is to look at real biological systems and to try to understand them.

> I can not see the link between CF-tuned hair cells and cochlea
amplification - currently ... the hair cells need to actuate some form
of mechanical model ... right ?

No, sorry. Not right. The hair cells need not "actuate" any model that is in 
anybody's head. The hair cells are there, and they do their job 
successfully. There is a vast amount of literature on hair cell tuning. It 
is our job to look at all the data and see what these cells do. It's not our 
job to fit some selected data to the models in our heads.

Just a few papers for a start:
