Described herein is a method of using functional MRI (fMRI) for determining brain activation patterns for a group of subjects in response to different odor-elicited feelings (i.e., conscious emotions). A method for preparing a perfume by using the method of the present invention and a consumer product including said perfume are also described herein.

fMRI method for determining brain activation patterns in response to odor elicited feelings

The compound of formulain which the wavy line represents a bond having a configuration of the type (Z) or (E), or a mixture of the two configurations; Rrepresents a hydrogen atom, a Cto Clinear or branched alkyl radical, a methoxy or ethoxycarbonyl radical, or an aryl radical, and Rrepresents a methyl or ethyl group, possess interesting organoleptic properties and can be advantageously used for the preparation of perfuming compositions to which it gives, in particular, a very natural connotation of the pear type.

Use of unsaturated esters as perfuming ingredients

The invention concerns (1-ethoxyethoxy-cyclododecane) which, although its smell is not noticed by a large number of people, can advantageously be used in a perfume composition as perfume exalting fixative.

Use of (1-ethoxyethoxy)cyclododecane in a perfume composition as perfume fixative and/or enhancer

The optically active compounds of formula ##STR1## wherein R.sup.1 represents a hydrogen atom or a methyl radical, or of formula ##STR2## are useful as perfuming ingredients for the preparation of perfuming compositions and perfumed articles to which they impart woody-amber notes.

Optically active aliphatic alcohols and their use as perfuming

Use of cyclic ketones in perfumery

Novel compounds of formula ##STR1## wherein the dotted lines indicate the location of a single or double bond, symbol R.sup.1 stands for a hydrogen atom or a methyl radical, symbol R.sup.2 represents a linear or branched, saturated or unsaturated, C.sub.1 to C.sub.4 alkyl radical, provided that R.sup.1 is not hydrogen when R.sup.2 represents a methyl or n-propyl radical and the ring is saturated. Compounds (Ia) are useful as perfuming ingredients. A process for their preparation is disclosed.

Cyclic ketones and their use as perfuming ingredients

New 4,4,5,8-tetramethyl-1-oxaspiro[2,5]octane. A process for its preparation starting from 2,2,3,6-tetramethyl-1-cyclohexanone is described. 4,4,5,8-Tetramethyl-1-oxaspiro[2,5]octane is a useful raw material for the preparation of 2,2,3,6-tetramethyl-cyclohexane-carbaldehyde, a key intermediate for the synthesis of valuable fragrance ingredients.
