Caresses enjoyable vicariously too

17.10.2011
It is well-known that we humans enjoy sensual caresses, but the brain reacts just as strongly to seeing another person being caressed, reveals research from the Sahlgrenska Academy at the University of Gothenburg, Sweden.

Being gently caressed by another person is both a physical and an emotional experience. But the way we are touched and the reaction this elicits in the brain are a science of their own.

The Soft Brush Test

Researchers from the Institute of Neuroscience and Physiology at the University of Gothenburg’s Sahlgrenska Academy have studied how the brain reacts to caresses. Volunteers were given MRI scans to measure blood flows in the brain while being stroked either slowly or quickly with a soft brush.

Same reaction via video

Not unexpectedly, the brain reacted most strongly to the slow strokes. More surprising results emerged when the volunteers instead watched videos of another person being caressed.

"The aim was to understand how the brain processes information from sensual contact, and it turned out that the brain was activated just as quickly when the volunteers got to watch someone else being caressed as when they were being caressed themselves," says India Morrison, one of the researchers behind the study. “Even when we are only watching sensual skin contact, we can experience its emotional meaning without actually feeling the touch directly."

Love or fight?

As a comparison, the volunteers also got to watch a video where a hand caresses an inanimate object, and in this case the brain was not activated anywhere near as strongly.

So what do these results mean?

“They indicate that our brain is wired in such a way that we can feel and process other people’s sensations, which could open up new ways of studying how we create empathy," says Morrison. “It's important for us as people to understand the significance of different types of touch – to know whether two people are in a relationship or are about to start a fight.”

The study has been published in the Journal of Neuroscience.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
