UCL study establishes common biological ground for maternal and romantic love in humans

13.02.2004


A new study of young mothers by researchers at University College London (UCL) has shown that romantic and maternal love activate many of the same specific regions of the brain, and lead to a suppression of neural activity associated with critical social assessment of other people and negative emotions. The findings suggest that once one is closely familiar with a person, the need to assess the character and personality of that person is reduced, and bring us closer to explaining why, in neurological terms, ‘love makes blind.’

In the experiment, published in February’s NeuroImage online preview edition, the brains of 20 young mothers were scanned while they viewed pictures of their own children, children they were acquainted with, and adult friends, to control for feelings of familiarity and friendship (the brain regions involved in romantic love having been identified by the authors in an earlier study).

The similarity of the activity recorded in this study compared to those obtained in the earlier study was striking; with activity in several regions of the brain overlapping precisely in the two studies. In summary, the findings showed that both types of love activate specific regions in the reward system, while reducing activity in the systems necessary for making negative judgements.



The new results demonstrated also that the mechanisms of love are similar in animals and humans, and that the brain regions activated are the same ones as respond to the brain-produced drugs oxytocin and vasopressin. These neuro-hormones have been shown in animals to be both sufficient and necessary to induce both mother-infant bonding and male-female bonding. The new research therefore provides a link to the previous work on animals, showing that the same ’love-potion,’ produced by the brain, known to work in animals is also at work in humans.

“Both romantic and maternal love are highly rewarding experiences that are linked to the perpetuation of the species, and consequently have a closely linked biological function of crucial evolutionary importance,” said Andreas Bartels, of UCL’s Wellcome Department of Imaging Neuroscience. “Yet almost nothing is known about their neural correlates in the human.

“Our research enables us to conclude that human attachment employs a push-pull mechanism that overcomes social distance by deactivating networks used for critical social assessment and negative emotions, while it bonds individuals through the involvement of the reward circuitry (regions in the brain that induce euphoric feelings), explaining the power of love to motivate and exhilerate.”

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
