Does your brain know what you smell? - fMRI odour labelling study

Av Androula Savva Skapad: 2026-05-19

In this study, we ask you to smell different odours. You will be asked to provide subjective ratings and make decisions based on what you smell in both sessions. Odours will be presented directly into your nostrils.

Session 1: We will also ask you to answer a couple of questions about demographic information and dietary preferences. All of this will occur in our testing lab, where you can complete the tasks on a computer. The session will take place at Karolinska Institutet (Campus Solna), Department of Clinical Neuroscience, Division of Psychology.

Session 2: You will complete odour ratings and a decision-making task in the MRI scanner. This session takes place at Stockholm University Brain Imaging Centre (Svante Arrhenius väg 16A). Complete reimbursement is paid after completion of the study.

If you have already participated in any part of our previous studies "What do you smell? An odour perception study" or “Do you know this smell? - An odour labelling study”, you are not eligible to participate.

Eligibility requirements:
Has a personal/ coordination number, 18-45 years, fluent in English, non-smoker/no use of snus, no psychiatric disorder, normal/ corrected-to-normal vision, has no braces or dental retainers, has no electrical implants (i.e. pacemakers)
