1. E-noses equipped with Artificial Intelligence Technology for diagnosis of dairy cattle disease in veterinary
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The main goal of this project, running at Neurofy AB, was that developing an AI recognition algorithm also known as, gas sensing algorithm or simply recognition algorithm, based on Artificial Intelligence (AI) technology, which would have the ability to detect or predict diary cattle diseases using odor signal data gathered, measured and provided by Gas Sensor Array (GSA) also known as, Electronic Nose or simply E-nose developed by the company. Two major challenges in this project were to first overcome the noises and errors in the odor signal data, as the E-nose is supposed to be used in an environment with difference conditions than laboratory, for instance, in a bail (A stall for milking cows) with varying humidity and temperatures, and second to find a proper feature extraction method appropriate for GSA.

2. Training of spider monkeys in a food-rewarded two-choice olfactory discrimination paradigm and assessment of olfactory learning and memory performance
University essay from Linköpings universitet/BiologiAbstract : There is little knowledge about olfactory learning in primates, even though primates are known to use olfaction in several behaviors including food selection and territorial defense. Therefore I assessed the olfactory learning and memory performance in five adult spider monkeys (Ateles geoffroyi) using a food-rewarded two-choice olfactory discrimination paradigm. READ MORE

3. Development and application of an olfactory discrimination paradigm for Asian elephants (Elephas maximus)
University essay from Institutionen för fysik, kemi och biologiAbstract : The sense of smell plays an important role in regulating the behavior of Asian elephants but until now, no behavioral test to systematically assess the olfactory capabilities of this species existed. Using a voluntary, food-rewarded two-alternative operant conditioning procedure, three female Asian elephants were successfully taught to discriminate between rewarded and unrewarded odors and also succeeded in intramodal stimulus transfer tasks in which either the rewarded odor, or the unrewarded odor, or both odors were exchanged simultaneously for new odors.

4. Toxoplasma gondiis roll vid beteendeförändringar hos djur
University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public HealthAbstract : På senare tid har man sett att gnagare, så som råttor och möss, kan drabbas av förändringar i beteendet när de blir infekterade med parasiten Toxoplasma gondii. Beteendeförändringarna verkar skapa förutsättningar för att parasiten lättare ska kunna fullborda sin livscykel, genom att infekterade gnagare blir lättare byten för huvudvärden, katten. READ MORE

5. Olfactory performance and neuropathology in the Tg6799 strain of Alzheimer’s disease model mice
University essay from Institutionen för fysik, kemi och biologiAbstract : The present study evaluated olfactory and cognitive abilities of the Tg6799 (also called 5xFAD) strain of Alzheimer’s disease (AD) model mice of two different age groups (2-3 and 8-10 months of age), and one group of healthy control mice (9-10 months). Employment of an operant conditioning paradigm using an automated olfactometer, an olfactory habituation/dishabituation test and a spatial learning test with non olfactory cues resulted in data showing that the 5xFAD mice develop olfactory impairments already at 2-3 months of age.
