A method of determining olfactory perception signature of a subject is disclosed. The method comprises: providing the subject with a plurality of physical odorant samples for sniffing; for each sniffed odorant sample, presenting to the subject, by a user interface, a set of odorant descriptors and a respective set of rating controls, and receiving ratings entered by the subject using the rating controls. Each rating is indicative of a descriptiveness of a respective odorant descriptor for the odorant sample, thereby obtaining a set of descriptiveness levels for the odorant sample. The method also comprises calculating, by a computer, relations between pairs of sets of descriptiveness levels corresponding to pairs of odorant samples, to provide a vector of relations, wherein the vector represents the olfactory perception signature of the subject.

The present disclosure relates to methods of assessing the ability of a test oral care flavour ingredient or a test oral care flavour composition to improve the invigoration state of a human subject and of creating oral care flavour compositions having an invigorating effect on a human subject. It further relates to oral care flavour compositions for improving the invigoration state of a human subject, to consumer products comprising such oral care flavour compositions, and to methods of improving the invigoration state of a human subject.

The present disclosure relates to methods of assessing the ability of a test fragrance ingredient or a test fragrance composition to improve the happiness state of a human subject and of creating fragrance compositions having a positive happy effect on a human subject. It further relates to fragrance compositions for improving the happiness state of a human subject, to consumer products comprising such fragrance compositions, and to methods of improving the happiness state of a human subject.

The present disclosure relates to methods of assessing the ability of a test oral care flavour ingredient or a test oral care flavour composition to improve the happiness state of a human subject and of creating oral care flavour compositions having a positive happy effect on a human subject. It further relates to oral care flavour compositions for improving the happiness state of a human subject, to consumer products comprising such oral care flavour compositions, and to methods of improving the happiness state of a human subject.

The present disclosure relates to methods of assessing the ability of a test oral care flavour ingredient or a test oral care flavour composition to improve the relaxation state of a human subject and of creating oral care flavour compositions having a relaxing effect on a human subject. It further relates to oral care flavour compositions for improving the relaxation state of a human subject, to consumer products comprising such oral care flavour compositions, and to methods of improving the relaxation state of a human subject.

The present disclosure relates to methods of assessing the ability of a test fragrance ingredient or a test fragrance composition to improve the relaxation state of a human subject and of creating fragrance compositions having a relaxing effect on a human subject. It further relates to fragrance compositions for improving the relaxation state of a human subject, to consumer products comprising such fragrance compositions, and to methods of improving the relaxation state of a human subject.

A method of screening a pupil of a subject to determine whether the pupil reflex resembles a canonical pupil reflex is disclosed. The method comprises the steps of stimulating the pupil with a stimulus source, such as a pupilometer and determining whether one of various pupillary response conditions is met.

The present system is directed in various embodiments to devices and methods for testing a patient's olfactory capability and/or sensitivity. The devices and methods may be used to test and compare a patient's ability to detect and/or identify an aroma or odorant presented to each nostril. Alternatively, the devices and methods may be used to generally assess, without regard to nostril-to-nostril comparative results, a patient's olfactory ability. The device may comprise a disk that comprises a plurality of odorant compartments that may be progressively advanced as the testing for a subject odorant is completed. The device may comprise a passive airway and an active airway, wherein only one nostril receives aroma-infused air while the other nostril receives atmospheric air. In other cases, the device may present aroma-infused air to both nostrils at the same time.

The present method is directed to determining whether a living, non-demented patient with Alzheimer's neuropathology, i.e., significant levels of amyloid plaque in the brain, is within the early pre-clinical stages of Alzheimer's disease. In turn, if the living, non-demented patient with Alzheimer's neuropathology is determined to not be in the early stages of Alzheimer's disease, then it may be concluded that the patient has at least a resistance to Alzheimer's disease neuropathology, and perhaps an immunity thereto, wherein the amyloid plaque does not localize to the patient's brain synapses, thereby preserving cognitive ability. A 3-step method comprising (1) conducting a cognitive test; (2) detecting brain plaque levels; and (3) conducting a bi-lateral olfactory sensitivity test using pure odorants is therefore provided.

Disclosed are an aroma diffusion module and an aroma diffusion container including the same. The aroma diffusion container according to an embodiment of the present invention includes a container body; an opening and closing unit coupled to the upper end of the container body; and an aroma diffusion module mounted in the container body, in which the aroma diffusion module includes a porous module body; a first hollow formed at one side of the module body; and a second hollow formed inside the module body, a porous aroma diffusion medium is accommodated in the first hollow, and the second hollow allows external air to be introduced into the container body through a slit of a membrane member unit. According to the present invention, there is an advantage of providing various types of aroma diffusion kits which can be efficiently used to feel, distinguish, memorize, and express aromas of favorite beverages and food, such as wine, coffee, tea, beer, and whiskey in which the aroma is important, while maximizing the number of use times as well as being easy to use and enabling a long-term storage.
