Source: Kerry M. Dooley and Michael G. Benton, Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA Both batch and continuous flow reactors are used in catalytic reactions. Packed beds, which use solid catalysts and a continuous flow, are the most common configuration. In the absence of an extensive recycle stream, such packed bed reactors are typically modeled as "plug flow". The other most common continuous reactor is a stirred tank, which is assumed to be perfectly...

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.

Responding for food or drug-paired cues increases over the course of a period of abstinence and this may relate to an increased susceptibility to relapse behaviors. Here we detail a procedure for evaluating this "incubation of craving" in rats that have self-administered sucrose.

Testing for Odor Discrimination and Habituation in Mice

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.
FAQs
The odor begins as a stimulus without established reward value, but repeated temporal association with sucrose allows its meaning to change. The animal can subsequently respond to the odor based on its learned relationship with the sugar reward. This shift provides evidence that experience has modified odor-guided behavior rather than merely eliciting an innate response.
Temporal association links the sensory event to the reward outcome. When odor and sucrose occur in a repeated relationship, the odor becomes informative about the sugar reward, strengthening the learned association. This timing principle makes the paradigm useful for examining how experience assigns value to sensory information and alters later behavioral responses.
This paradigm can be used to study associative learning, memory formation, reward processing, and olfactory behavioral plasticity. In combination with measurements of behavior, it helps researchers examine how neural circuits encode the value of an odor and modify responses after experience. The approach therefore connects sensory processing with learning-related changes in behavior.
A typical design first establishes the animal’s response to an odor before learning, then repeatedly presents that odor in temporal association with sucrose. Researchers subsequently assess odor-guided behavior and compare it with the preconditioning response. This before-and-after structure allows the behavioral effect of the pairing to be evaluated directly.
The comparison shows whether experience changes the behavioral significance of the odor. An altered post-training response is consistent with learned odor-guided plasticity associated with the sucrose relationship. Such measurements can help distinguish changes linked to associative learning and memory from the animal’s initial response to the sensory stimulus.
Its value comes from linking a defined sensory cue with a reward while allowing behavioral change to be measured. Researchers can use the paradigm to examine how reward experience influences olfactory behavior and how neural circuits encode sensory value. It provides a behavioral framework for studying the interaction among odor processing, reward, learning, and memory.
