This manuscript describes a protocol to examine the olfactory system of rodents. The olfactory habituation/dishabituation test will allow investigators to determine whether a mouse habituates to a repeatedly presented odor and whether the mouse demonstrates dishabituation when presented a novel odor.

Behavioral Determination of Stimulus Pair Discrimination of Auditory Acoustic and Electrical Stimuli Using a Classical Conditioning and Heart-rate Approach

The application of a classical fear conditioning behavioral paradigm for auditory prosthetic research in rats is described. This paradigm provides a mechanism for identifying both detection of, and discrimination between, distinct acoustic and electrical stimuli using heart-rate as an outcome measure.

Stereotypes, Prejudice, and Discrimination

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who are...

In this video, a live Drosophila fly is mounted in a tube for electrophysiological studies. Electrodes are positioned at the base of the sensillum to record specific neuronal responses to pheromones with the fly's olfactory receptor neurons.

High-resolution Measurement of Odor-Driven Behavior in Drosophila Larvae

In this video article, we describe a new method allowing the construction of odorant gradients with stable and controllable geometries. We briefly illustrate how these gradients can be used to screen for olfactory defects (full and partial anosmia) and to study more subtle features of chemotaxis behavior.
FAQs
The odor functions as a cue within a learned relation between a response and its consequence. When reinforcement has consistently followed a response under one odor condition, that condition changes the likelihood of responding; it does not compel the response. This distinction lets investigators analyze how sensory information sets the occasion for behavior.
Reinforcement gives the odor behavioral significance by making the response-consequence relationship more reliable in that condition. If the same response is reinforced less reliably when the odor is absent or another odor is present, the organism can learn to use odor differences when selecting responses. The resulting pattern demonstrates stimulus control through contingencies.
Olfactory discrimination examines whether behavior differs across odor conditions, whereas generalization examines how responding relates to changing environmental cues beyond the most specific trained condition. Considering both prevents stimulus control from being interpreted as an isolated odor-response link. Together, they show how broadly an organism applies learned sensory information during response selection.
During conditioning, present an odor condition while observing a target response, then arrange the relevant consequence for that response. Compare this pattern with conditions in which the odor is absent or another odor is present and reinforcement is not, or is less, reliable. This comparison reveals whether odor conditions guide responding.
Response patterns can show whether an organism uses odor information to select among available behaviors. Researchers can relate those observable choices to the reinforcement contingencies arranged across odor conditions, helping assess stimulus control and olfactory discrimination. The findings also clarify how sensory information and consequences jointly relate to learned behavior.
Changing odor cues allow investigators to examine behavior across environmental conditions rather than under a single unchanging signal. In behavior research, this supports analysis of learning, stimulus control, olfactory discrimination, and generalization. It also helps reveal how animals adjust response selection when the sensory information associated with consequences changes.
