Note: As I warned earlier, the Yin lab website is no longer accessible to the public. Just as the university blocked informed critics from posting on its Facebook page, it has now censored any public inspection of the Yin lab's website. Funny, in a sad anti-democracy anti-education sort of way.]
Normal people will find the video above a little disturbing.... I don't know the date of the photos, but I'm certain that they come from the Yin lab. Some years ago I stumbled across the Yin Lab webpage and snagged these photos (they seem like a happy crew.)
That's Tom Yin in front. The photos were part of a spread on the construction of the lab's new (at the time) sound proof chamber for conducting its experiments on cats. It's mentioned in many of Yin's papers; the tall fellow in the back is his main collaborator -- Daniel J. Tollin, Associate Scientist. Ph.D., 1998, University of Oxford.
Here are a couple of links to Yin's info at the university. (It might disappear anytime now.)
Check out this video as well before its gone too. It's from the Yin lab. It's much less forthcoming than the PETA video. In the Yin video, it appears that the cat's head is fixed in place. http://www.neurophys.wisc.edu/yin/pinna.asf
As I mentioned above, Yin's main collaborator is Danial J. Tollin, seen here pretending to be a cat before he digs into her brain and ears:
Here's a picture of Tollin's house he kindly added to his university webpage. Proving once again the vivisectors' humility and the austerity and slave wages they endure in their efforts to save humanity:
Here's the main PETA page on this. (They don't mention Yin or Tollin by name; it's my understanding that they can't mention who the researchers are. I'm not similarly constrained.)
Here's the Wisconsin State Journal article -- no photos, no link to PETA's photos. Now that's good reporting!
Here are some links to some of his published papers. Check out the Materials and Methods sections.
Short-latency, goal-directed movements of the pinnae to sounds that produce auditory spatial illusions. Tollin DJ, McClaine EM, Yin TC. J Neurophysiol. 2010:
METHODSSound-localization performance in the cat: the effect of restraining the head. Tollin DJ, Populin LC, Moore JM, Ruhland JL, Yin TC. Journal of Neurophysiology 2005.
Three adult female cats were behaviorally trained to localize sound sources using operant conditioning procedures and food reward. Each cat was surgically fitted with a head post and eye and pinna coils made of fine wire (Cooner Wire, Chatsworth, CA). A detailed description of the surgical and behavioral procedures are given in Populin and Yin (1998a). The magnetic search coil technique was used to monitor eye and pinna position (Fuchs and Robinson 1966) by implanting eye coils around the eye ball and pinna coils subcutaneously behind the pinna as described earlier (Populin and Yin 1998b; Tollin et al. 2009). The eye coils were 18 to 19 mm in diameter, and the pinna coils were 10 mm in diameter. The head was restrained by a head post in these experiments. All procedures used were approved by the University of Wisconsin Animal Use and Care Committee [this is misleading since there are more than one -- guess it's best not to be too specific.] and also complied with the National Institutes of Health [miserably weak] guidelines for animal use.
Cats were food deprived 5–6 d/wk once training began. Body weight was monitored daily and maintained within 15% of pre-experimental weight. Water was provided ad libitum, and the animals were fed without restriction on nontesting days. Once accustomed to the head restraint, cats were trained to make saccades to locations of visual and acoustic stimuli in a dark, anechoic chamber.
Psychophysical investigation of an auditory spatial illusion in cats: the precedence effect. Tollin DJ, Yin TC. J Neurophysiol. 2003: "Five adult female cats chosen for their friendliness and clean middle ears were used in these experiments."
Here's the university's tepid response to all this: Statement regarding sound localization research at UW-Madison.
