Toxoplasma gondii reportedly manipulates rodent behaviour to increase transmission to its definitive feline host. We compared the effects of mouse infection by two Type II strains of T. gondii, Prugniaud (PRU) and ME49, on attraction to cat odour, locomotor activity, anxiety, sensorimotor gating, and spatial working and recognition memory 2 months post-infection (mpi). Attraction to cat odour w...

The article presents a benchmark (OlfMark) to evaluate the performance of mobile robot odour source localisation tasks. The problem of finding odour sources with mobile robots is introduced and a set of materials commonly employed in this task are described. The OlfMark represents a first step in order to define methodologies to run olfactory experiments and compare results obtained with differ...

This review paper presents different ways to apply a measurement instrument of e-nose type to evaluate ambient air with respect to detection of the odorants characterized by unpleasant odour in a vicinity of municipal processing plants. An emphasis was put on the following applications of the electronic nose instruments: monitoring networks, remote controlled robots and drones as well as portab...

Perceptually similar stimuli often predict vastly different outcomes, requiring the brain to maintain specific associations in the face of potential ambiguity. This could be achieved either through local changes in stimulus representations, or through modulation of functional connections between stimulus-coding and outcome-coding regions. Here we test these competing hypotheses using classical ...

Toxic odour causes pollution to environment. Removal of odour from wet processing sections of leather tanneries is important to preserve safety and occupational health. Such odour causing gases are identified in nature and are identified mostly as ammonia, Hydrogen sulfide and Volatile organic compounds. These gases, evolving from tanning drums, were experimentally quantified and analysed. Tech...

BACKGROUND Human axillary odour is commonly attributed to the bacterial degradation of precursors in sweat secretions. To assess the role of bacterial communities in the formation of body odours, we used a culture-independent approach to study axillary skin microbiota and correlated these data with olfactory analysis. RESULTS Twenty-four Caucasian male and female volunteers and four assessors...

Spontaneous walking by Ixodes ricinus nymphs in the horizontal plane was investigated within choice arenas to test whether these ticks move preferentially up a humidity gradient, and whether they are attracted towards host odour, specifically volatile substances from the back of a dog's ear. Responses by ticks with high and low fat contents and in different states of hydration were compared. Ti...

Monitoring and analysis of livestock farm environments require collection and management of large amount of data from distributed farms. There is an increasing demand for collaboration among livestock producers, environment agencies and governments. This paper presents a collaborative system for monitoring and analyzing livestock farm odours remotely, and for enhancing the collaboration among u...

This paper presents a complete approach of continuous odour monitoring around an industrial plant, with an e-nose network named FIDOR, providing in real time the five components of the odour annoyance, the frequency, the intensity, the duration, the offensiveness and the impact on the receptor. Such FIDOR network was placed in the immediate surroundings of a compost facility in Belgium. Results...

Some words immediately and automatically remind us of odours, smells and scents, whereas other language items do not evoke such associations. This study investigated, for the first time, the abstract linking of linguistic and odour information using modern neuroimaging techniques (functional MRI). Subjects passively read odour-related words ('garlic', 'cinnamon', 'jasmine') and neutral language...
