“For most animals, smell is a very, very important thing,” said Harvard Professor Venkatesh Murthy. “If they are in an environment where there’s one overwhelming smell that’s irrelevant, they need to be able to detect a weak smell that may signal danger.” Earlier studies had hinted that the interneurons in the olfactory bulb are the primary target of the feedback signals, but Murthy’s study is the first to prove it.

Handlers’ Beliefs Affect Explosive- And Drug-Sniffing Dog Performance
02 Feb 2011
Drug- and explosives-sniffing dog/handler teams’ performance is affected by human handlers’ beliefs, possibly in response to subtle, unintentional handler cues, a study by researchers at UC Davis has found. Continue reading Handlers’ beliefs & Drug Dog Performance
Dogs can be trained to correctly identify certain prostate cancer cell-derived volatile organic compounds (VOCs) in urine, according to new data from researchers in Paris. These promising new data were presented on June 1, 2010 during the 105th Annual Scientific Meeting of the American Urological Association (AUA). The session was moderated by AUA Public Media Committee Chair Anthony Y. Smith, MD.

The high mortality rate associated with ovarian carcinoma is mainly owing to late diagnosis. It is thus essential to develop inexpensive and simple methods for early diagnosis. Papers on canine scent detection of malignancies such as melanoma and bladder, lung, and breast cancer have recently been published in peer-reviewed journals, indicating a new diagnostic tool for malignancies.
“The use of canines, Canis lupus var. familiaris, in law enforcement is widely accepted; however, there are few peer-reviewed studies confirming their accuracy and reliability. The use of detector dogs for human-scent lineups has been used in Europe, including Belgium, Denmark, Germany, Hungary, the Netherlands, Poland, and Russia, but has not gained widespread acceptance in the United States, mainly due to the lack of definitive studies demonstrating the reliability of this approach. Published results pertaining to the accuracy of canines used in human-scent lineups will be discussed later in the text.”

“This website is a work in progress and is subject to change, but my intention is to first outline the ways in which knowledge about the relations between events is gained. Then explain what discrimination training really involves, what animals are learning during the course of discrimination training, and offer a user friendly, applied science plan for scent discrimination training.” E. Hale
This a a great website for scientific information relating to reinforcement, cause and effect relationships and scent discrimination.
