Assessing the behavioral response of Westslope Cutthroat Trout to olfactory cues in a two-choice Y-maze
… clarkii lewisi (WCT) in a two-choice Y-maze. WCT used in this study were from Kings Lake and Paqua Creek in Pend Oreille County, Washington, and tested in 2018 and 2019. The different odorants tested in this study were population-specific pheromones produced by WCT from the same …

Reinstatement in an Appetitively Motivated Paradigm
… on a light-dark discrimination task in a Y-maze. At 7, 14, and 21 days thereafter they received reinstatements consisting of either two reinforced trials in the Y-maze (group I) or one reinforced and one non-reinforced trial in a specially prepared straight alley (group II) which presented …

Demonstration of pheromonal activity in the breeding glands of dwarf African clawed frogs (Hymenochirus sp.)
… sp. are able to attract females in a Y-maze, most likely through chemical means, but the source of the attractant has not been identified. By exposing female Hymenochirus sp. to choice tests in a Y -maze it was demonstrated that the breeding glands of male Hymenochirus sp. are the source …

The Efects of Dose and Time of Administration of Pentylenetetrazol on a Visual Discrimination Task
… to perform a brightness discrimination in a Y-maze until they reached a criterion of nine out of ten correct responses. They were then injected with either 10.0, 12.5 or 15.0 mg/kg pentylenetetrazol at intervals of either 0,5 or 15 minutes after completion of training. Twenty-four hours later a …

SPECIES RECOGNITION IS DRIVING EVOLUTION OF THE ACOUSTIC MATING SYSTEM OF SHIELD BACK KATYDIDS (ORTHOPTERA: TETTIGONIIDAE: AGLAOTHORAX): BEHAVIORAL AND PHYLOGENETIC EVIDENCE
… interval, the former with choice tests on a Y-maze and the latter with no-choice tests on a locomotion compensator. Females of two coexisting Transverse Range species each discriminated against the interpulse intervals of the other. Phylogenetic relationships inferred from nuclear gene …

Habituation, Scent-Trailing, and Effects of Temperature Upon the Strike-Induced Chemosensory Searching (SICS) in the Cottonmouth (Agkistrodon Piscivorus)
… scent trails to locate hibernacula using Y-maze experiments. Neonatal cottonmouths showed no preference for the odors of their mothers, conspecifics, or heterospecifics when paired with a control. This result suggests that neonatal cottonmouths at our study site rely on factors other than …

Sleep oscillations and their temporal association in neocortices in mice
… S1 by conducting a PFC dependent appetitive Y-maze and a S1 dependent object exploration task. Task performance enhanced slow wave activity and sigma activity in both cortices, while learning of Y-maze was predicted by a closer temporal association between slow waves and spindles in PFC. In …

Habitat use and responses to odours by rodents in New Zealand
… might avoid the odours of other rats in a Y maze, but ship rats (R. rattus) and Norway rats were less responsive to heterospecific odours. Mice (Mus musculus) in laboratory trials could apparently distinguish the odour of rats from their own odour, but did not avoid rat odour. However, when …

Host Attraction and Host Selection in the Family Corethrellidae (Wood And Borkent) (Diptera)
… Corethrella appendiculata was tested in a Y-maze. The data confirmed that C. appendiculata was more attracted to a frequency-rich sound and not to a sound that resembles their wing-beat frequency. For the first time, the hosts of corethrellids were identified to species based on blood meal …

The role of heterozygous lysosomal storage disorder alleles as risk factors for dementia
… not have memory impairments detectable in a Y-maze, novel object recognition test or Morris water maze at six-months. They did, however, exhibit reduced open field activity and lysosomal network disruptions. Lysosome-associated membrane protein 1 and cathepsins B, L and D accumulated at amyloid …

Vulnerability to cognitive, neurotoxic and neuroinflammatory effects of toxins that induce Parkinson's disease after administration of amphetamine-related drugs in mice
… (NOR) and spontaneous alternation in a Y-maze tests. MPTP administration to MDMA-pretreated mice elicited a stronger increase in CD11b and GFAP levels in motor, limbic and cortical areas, and a stronger decrease of TH-positive neurons and fibers in motor areas, compared with either …

The Effects of Prenatally Induced Hypothyroidism of the Neural Development and Problem Solving Ability of Maturing Hypothyroid Rats
… controls. Intelligence was tested with a Y-maze at 4 weeks of age and 8 weeks of age. At 8 weeks all rats were sacrificed and brains were removed and fixed for histological study. Findings. Experimental rats learned markedly more slowly than did the control rats. Control rats had …

Modulation of Alzheimer’s Disease Pathology by Collagen-Induced Rheumatoid Arthritis in APP/PS1 Mice
… based on the performance in the MWM and the Y-Maze and reduced amyloid plaque pathology. Additionally CIA mice increased cerebrovascular pathology and mortality. The present findings suggest that RA may exert beneficial effects against Aβ burden and harmful effects on cerebrovascular pathology …

Behavioral measurements of visual processing in adult male and female hooded rats: Do visual tasks reflect sex differences in visual cortex morphology?
… Grating acuity was measured in a forced choice Y-maze and a jumping stand. Using a criterion of 34 correct/50 trials, grating acuity for both sexes was high (1.0-1.6 cycle/degree). Females made more correct identifications of the coarse gratings (0.125 and 0.25 c/deg) than males, but no sex …

Genetic dissection of variability in cognitive and locomotor phenotypes using Drosophila melanogaster
… using an appetitive olfactory conditioning Y-maze behavior assay for phenotyping. After phenotyping 50 recombinant inbred lines (RILs) I conducted high resolution genome wide scans to identify quantitative trait loci (QTL) with contribution to both phenotypes which established these behaviors …

Assessing the impact of domoic acid exposure on the zebrafish (Danio rerio) brain across life stages
… adult treatment on behavior in novel tank or Y-maze spatial discrimination assays. This thesis contributes to our understanding of neurodevelopmental effects of DA exposure during developmental and adult life stages, emphasizing the potential for microglia as a target of DA.

Learning and Olfactory Processing by the Parasitic Wasp, Cotesia Congregata, In Response to Concentration of Herbivore Related Tomato Volatiles
… assayed 18-24 hours after conditioning in a Y-maze olfactometer. Wasps were conditioned in the presence of the complete volatile blend emitted by wounded tomato leaves (Solanum lycopersicum `Castlemart') and their attraction was assayed using controlled dose/emissions of cis-3-hexen-1-ol (green …

The utilization of chemical communication by three species of ghost shrimp, Callichirus islagrande, Callichirus major, and Lepidophthalmus louisianensis, and the transport of chemical cues within and between burrows
… performed in three parts. A set of modified y-maze choice experiments were performed to establish the ability of three species of ghost shrimp, Callichirus islangrande, Callichirus major, and Leptidophthalmus louisianensis, to detect conspecifics via chemical cue. The time budgets for the …

Biobehavioral responses to immune skew and free fatty acids
