Odor cues in a maze discrimination
TLDR
Rats were found capable of making the choice in a T-maze using the odor from only one 45-mg Noyes food pellet as a discriminative stimulus, pointing to the need for controlling odor stimuli in the traditional food-reinforcement situation, and especially in studies concerned with the magnitude of reward.Abstract:

Intramaze cues and “odor trails” fail to direct choice behavior on an elevated maze
TL;DR: Rats in the extramaze group performed almost perfectly during maze rotation, demonstrating that intramaze cues were not necessary to support accurate choice behavior, and other experiments describing the influence of “odor trails” or other olfactory stimuli on choice behavior in mazes are compared.

Social olfaction: a review of the role of olfaction in a variety of animal behaviors.
Marylou Cheal,Richard L. Sprott +1 more
TL;DR: The importance of olfaction to the social behavior of animals is shown by tracing the history of the experimental evidence and viewing the behavioral data pertaining to the discharge of pheromones and their effects to look at the psychophysical evidence for olfactory acuity.

Visual lesions and radial maze performance in rats.
Nigel Foreman,Robin Stevens +1 more
TL;DR: Initial learning of the eight-arm radial maze was examined in groups of rats having either bilateral superior colliculus or posterior (visual) cortical lesions, suggesting that these two types of lesion affect different aspects of performance.

Olfactory Stimulus Control Evaluated in a Small Animal Olfactometer
TL;DR: Studies with rats using a discrete trials, go, no-go training procedure demonstrate that olfactory discriminations are acquired rapidly and, under appropriate conditions, with few or no errors.

The sweet smell of success: Apparent double alternation in the rat
H. Wayne Ludvigson,Donald Sytsma +1 more
TL;DR: The hypothesis that rats exude odors which, depending on the manner in which the study is conducted, can serve as a powerful source of contamination among treatments or among Ss within a treatment is supported.

The odor of taste solutions
TL;DR: It is shown here that rats can smell chloride salts at concentrations near the taste threshold, and it seems advisable that animals used in taste experiments be deprived of the olfactory sense.
