Odor profiling of environmental odors

Water Science and Technology, 1999
There is a need to standardize a field procedure for odor profiling of environmental odors. There is a need to drive the analytical procedures toward a practical, useful method for profiling odors in contrast to highly complex instrumentation or lab-based techniques. A technique for profiling odors, and tracking odor sources will be outlined.

The subapical labial sensory organ of spotted lanternfly Lycorma delicatula

Open Biology
Deciphering how spotted lanternfly (SLF), an invasive polyphagous planthopper in North America, engages with its environment is a pressing issue with fundamental biological significance and economic importance.

Can the Identification of Odorants Within a Mixture Be Trained?

Chemical Sensors, 2018
Identifying odors within mixtures is a difficult task: humans are able to recognize only up to 4 odors within a mixture. We wanted to test the effects of olfactory training on this ability. We used 7 odorants to create 35 olfactory stimuli of 1, 2, 3, 4,

Deep Nearest Class Mean Model for Incremental Odor Classification [PDF]

IEEE Transactions on Instrumentation and Measurement ( Volume: 68 , Issue: 4 , April 2019 ) 952 - 962, 2018
In recent years, more machine learning algorithms have been applied to odor classification. These odor classification algorithms usually assume that the training datasets are static. However, for some odor recognition tasks, new odor classes continually emerge. That is, the odor datasets are dynamically growing while both training samples and number of

Engaging and disengaging recurrent inhibition coincides with sensing and unsensing of a sensory stimulus [PDF]

, 2017
Even simple sensory stimuli evoke neural responses that are dynamic and complex. Are the temporally patterned neural activities important for controlling the behavioral output? Here, we investigated this issue.

Effect of acute copper sulfate exposure on olfactory responses to amino acids and pheromones in goldfish (Carassius auratus) [PDF]

, 2009
Exposure of olfactory epithelium to environmentally relevant concentrations of copper disrupts olfaction in fish. To examine the dynamics of recovery at both functional and morphological levels after acute copper exposure, unilateral exposure of ...

Odors Cue Memory for Odor-Associated Words [PDF]

Chemosensory Perception, 2009
The ability of odors to cue vivid and emotionally intense memories is well-known. However, the majority of research has focused on the extent to which odors can act as environmental cues to memory, where odors are presented alongside the stimuli to be remembered, rather than the extent to which pre-existing associations between odor and odor-related ...
