Moisturising cream – read the label



The 2024 Global Year will examine what is known about sex and gender differences in pain perception and modulation and address sex-and gender-related disparities in both the research and treatment of pain.

Here is a cool study from Oxford University – they led participants to believe that they were applying either a ‘rich moisturising cream’ or a ‘basic cream’ to their forearm and asked them to rate how it felt – pleasantness and richness etc. They also scanned their brains.

The team reports that

These new findings thus show that cognitive modulation influences affective representations of touch and/or the sight of touch in a pregenual/orbitofrontal cortex system in which another somatosensory stimulus, oral texture, is represented [1]; in which correlations with pleasantness ratings are found [2,3,4]; and in which pleasant touch produces activation [5].

Of course, one always has to be careful not to interpret brain imaging findings as a neophrenologist might and conclude that the pregenual/orbitofrontal system actually holds ‘pleasantness’, which would imply that if we took it out of the brain it could somehow produce pleasantness by itself.  I reckon we can be confident with this fMRI data to conclude that the participants were not lying – that what they thought they were getting modulated how it felt.  This reminds me of a study using expensive vs cheap wine…..

If you are interested in these things – check out Charles Spence’s stuff – including the work for which he won the Ignoble Prize.
