The pain and anguish of rejection by a romantic partner may be the result of activity in parts of the brain associated with motivation, reward and addiction cravings, according to a study published in the July issue of the Journal of Neurophysiology (http://jn.physiology.org/).
The study’s findings could have implications for understanding why feelings related to romantic rejection can be hard to control, and may provide insight into extreme behaviors associated with rejection, such as stalking, homicide and suicide—behaviors that occur across many cultures throughout the world.Study Design and Findings
Participants each viewed a photograph their former partners. Then they completed a simple math exercise, such as counting backwards from a random four-digit number by 7, to distract them from their romantic thoughts. Finally, they viewed a photograph of a familiar “neutral” person, such as a roommate’s friend.
The researchers found that looking at photographs of the participants’ former partners stimulated several key areas of the participants’ brains more than looking at photos of neutral persons did. The areas are:
• the ventral tegmental area in the mid-brain, which controls motivation and reward and is known to be involved in feelings of romantic love,
• the nucleus accumbens and orbitofrontal/prefrontal cortex, which are associated with craving and addiction, specifically the dopaminergic reward system evident in cocaine addiction, and
• the insular cortex and the anterior cingulate, which are associated with physical pain and distress.
The researchers note that their findings supply evidence that “the passion of ‘romantic love’ is a goal-oriented motivation state rather than a specific emotion” and that their results are “consistent with the hypothesis that romantic rejection is a specific form of addiction.” Those who are coping with a romantic rejection may be fighting against a strong survival system that appears to be the basis of many addictions. The data help to explain why the beloved is so difficult to give up.Hope for the Lovelorn

Physiology is the study of how molecules, cells, tissues and organs function to create health or disease. The American Physiological Society (APS) has been an integral part of this scientific discovery process since it was established in 1887.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
