1. 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

2. Olfactory discrimination ability of South African fur seals (Arctocephalus pusillus) for enantiomers
University essay from Institutionen för fysik, kemi och biologi; Tekniska högskolanAbstract : The sense of smell in marine mammals is traditionally thought to be poor. However, increasing evidence suggests that pinnipeds may use their sense of smell in a variety of behavioral contexts including communication, foraging, food selection, and reproduction. READ MORE

3. Olfactory discrimination performance and longterm odor memory in Asian elephants (Elephas maximus)
University essay from Institutionen för fysik, kemi och biologi; Tekniska högskolanAbstract : Behavioral evidence suggests that Asian elephants strongly rely on their sense of smell in a variety of contexts including foraging and social communication. Using a food-rewarded two-alternative operant conditioning procedure, three female Asian elephants were tested on their olfactory discrimination ability with 1-aliphatic alcohols, n-aldehydes, 2-ketones, n-carboxylic acids and with a set of twelve enantiomeric odor pairs.

4. 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.

5. Olfactory and cognitive abilities in two strains of Alzheimer`s disease model mice
University essay from Institutionen för fysik, kemi och biologiAbstract : The present study assessed olfactory and cognitive abilities in two strains of Alzheimer’s disease (AD) model mice and in healthy control mice over a four month time period. To this end an operant conditioning paradigm using an automated olfactometer and a spatial learning test with non-olfactory cues were employed and data on olfactory learning and memory, discrimination, and sensitivity as well as spatial learning and memory were collected.
