A Colorimetric Artificial Olfactory System for Airborne Improvised Explosive Identification

Advances in Materials, 2020
The detection of ultralow or nonvolatile target analytes remains a significant challenge for artificial olfactory systems even after decades of development, which severely limits their widespread application.

Imaging of the olfactory system

Seminars in Ultrasound, CT and MRI, 2001
The olfactory system consists of the primary olfactory nerves in the nasal cavity, the olfactory bulbs and tracts, and numerous intracranial connections and pathways. Diseases affecting the sense of smell can be located both extracranially and intracranially. Many sinonasal inflammatory and neoplastic processes may affect olfaction.

Computation in the Olfactory System

Chemical Senses, 2005
Computational models are increasingly essential to systems neuroscience. Models serve as proofs of concept, tests of sufficiency, and as quantitative embodiments of working hypotheses and are important tools for understanding and interpreting complex data sets.

Olfactory systems for medical applications

Sensors and Actuators B: Chemical, 2008
Prevention strategy is nowadays the main way in the complex issue of medical diagnosis. In this wake, performing non-invasive medical tests oriented to an early diagnosis is one of the challenges for the promotion of new classes of instruments and for a faster intervention on the patient.

Anatomy of the olfactory system

2019
Of the principal sensory systems (vision, olfaction, taste, hearing, and balance), olfaction is one of the oldest. This ubiquitous system has both peripheral and central subdivisions. The peripheral subdivision is comprised of the olfactory epithelium and nerve fascicles, whereas the central subdivision is made up of the olfactory bulb and its central ...

Olfactory and Limbic Systems [PDF]

, 1987
These two systems are reviewed together as they are closely related to each other, and a number of structures are common to both systems. Olfactory sensation serves an obvious function in providing us with information regarding this aspect of the surroundings.

Evolving olfactory systems on the fly

Trends in Genetics, 2010
The detection of odour stimuli in the environment is universally important for primal behaviours such as feeding, mating, kin interactions and escape responses. Given the ubiquity of many airborne chemical signals and the similar organisation of animal olfactory circuits, a fundamental question in our understanding of the sense of smell is how species ...

The Mouse Olfactory System [PDF]

, 2020
For mice the olfactory system is a very important resource for exploration of the environment and for reproductive behavior. The olfactory system consists of two parts defined by the type and location of the primary sensory neurons and by a different connectivity pattern.

Chronic stress impacts on olfactory system.

CNS and Neurological Disorders - Drug Targets, 2015
Chronic stress has detrimental effects on brain structures and functions. Previous studies mainly focused on prefrontal cortex and hippocampus, given their well-described roles in cognition and emotive processing.

Spatiotemporal representations in the olfactory system

Trends in Neurosciences, 2007
A complete understanding of the mechanisms underlying any kind of sensory, motor or cognitive task requires analysis from the systems to the cellular level. In olfaction, new behavioural evidence in rodents has provided temporal limits on neural processing times that correspond to less than 150ms--the timescale of a single sniff.
