Ten women and 7 men married an average of Control images included a highly familiar acquaintance; a close, long-term friend; and a low-familiar person.

Effects specific to the intensely loved, long-term partner were found in: i areas of the dopamine-rich reward and basal ganglia system, such as the ventral tegmental area VTA and dorsal striatum, consistent with from early-stage romantic love studies; and ii several regions implicated in maternal attachment, such as the globus pallidus GP , substantia nigra, Raphe nucleus, thalamus, insular cortex, anterior cingulate and posterior cingulate. Overall, suggest that for some individuals the reward-value associated with a long-term partner may be sustained, similar to new love, but also involves brain systems implicated in attachment and pair-bonding.

For centuries, humans have speculated about the mysteries of romantic love. One question that has puzzled theorists, therapists and laypeople is whether intense romantic love can last. Some theories suggest that love inevitably declines over time in marriage or after the child-rearing years Sternberg, ; Buss, Some psychologists even speculated that the presence of intense passion in long-term marriages may sometimes exist, but is an indication of over-idealization or pathology Freud, ; Fromm, However, other theories suggest that there might be mechanisms through which romantic love may be sustained over time in relationships.

Our first hypothesis was that long-term romantic love is similar to early-stage romantic love. We used functional magnetic resonance imaging fMRI approaches used by investigations of romantic love Aron et al. Our second hypothesis was that long-term pair-bonds share neural circuitry with parent—infant bonds.

Since then, studies have applied attachment theory to adult romantic relationships Hazan and Shaver, ; Mikulincer and Shaver, with some researchers suggesting that pair-bonds and parent—infant bonds share common biological substrates Fisher, ; Carter, Thus, adult attachment work has been built on the notion that pair-bonds are the adult instantiation of attachment in childhood Ainsworth, We investigated the neural correlates of long-term romantic love and attachment by applying fMRI to a group of long-term happily married, sexually monogamous individuals reporting intense romantic love for their partner.

We duplicated procedures used in Aron et al. We predicted that long-term romantic love would involve dopamine-rich subcortical brain regions associated with reward, particularly the ventral tegmental area VTA , reported in several studies of early-stage romantic love Bartels and Zeki, ; Aron et al.

We added a control for social affiliation by including a close, long-term friend as a comparison target. A social affiliation control allowed us to examine attachment-related neural activity in response to the partner. This was important for examining commonalities found for pair-bonds from the present research with studies of parent—infant bonds Bartels and Zeki, ; Strathearn et al.

Our regions of interest, notably the globus pallidus GP , were based on human imaging studies of maternal attachment Bartels and Zeki, ; Strathearn et al. Finally, we conducted correlations of neural activity with widely used questionnaire measures of romantic love, obsession, inclusion of other in the self IOS , friendship-based love, relationship length and sexual frequency. Relationship researchers have addressed other aspects of love that are useful when considering the possibility of long-term romantic love.

Hendrick and Hendrick speculated that people go through a development sequence of love styles, with Mania or obsession being most characteristic of adolescents, evolving into Eros romantic love around early adulthood, Storge akin to companionate love and Pragma pragmatic love in the middle years and eventually into Agape all-giving love in the later stages of life. Other research suggests that there might be mechanisms through which romantic love may be sustained or increased at all stages of relationships.

For example, the self-expansion model Aron and Aron, proposes that romantic love is the experience of rapid self-expansion by including a particular person in the self Aron et al. In the early-stages of relationships, partners experience rapid self-expansion as they learn and integrate new aspects of the beloved.

Opportunities for rapid expansion—which tend to decrease as the couple comes to know each other well—may be maintained if partners continue to expand, seeing each other as new and experiencing expansion by way of the relationship. Similarly, the intimacy model suggests that rapid increases in intimacy promote increases in passion Baumeister and Bratslavsky, Acevedo and Aron suggest that intense romantic love with intensity, engagement and sexual desire exists in some long-term relationships, but generally without the obsession component common in the early-stages of relationships.

Finally, in-depth interviews carried out by a member of our research team BPA suggest that some individuals in long-term love report symptoms common to newly in love individuals: craving for union, focused attention, increased energy when with the partner, motivation to do things that make the partner happy, sexual attraction and thinking about the partner when apart. Thus, we embarked on this study to examine how brain system activity in those who report being intensely in love after 10 years might be similar to and different from early-stage romantic love.

Seven participants were in a first marriage for both partners , and 10 were in marriages where one or both partners had been ly divorced. On average, participants had completed 16 years s. All participants provided informed consent and received payment for their participation. Participants also reported sexual frequency with their spouse and other relationship demographics. Facial color photographs of four stimuli for each participant were digitized and presented using E-Prime 2.

All controls were the same sex and approximately the same age as the partner. Means and s. Immediately after the set of image presentations, while still in the scanner, participants rated the emotional intensity elicited by each stimulus. The feelings rated were compassion, friendship, joy, pride, love, passion and sexual desire.

are displayed in Figure 1. Postscan emotion intensity ratings. The y -axis indicates the mean of the intensity ratings given by participants to their long term, intensely loved partner Partner , close friend CF , a highly-familiar neutral HFN acquaintance and a low-familiar neutral LFN acquaintance. A score of 1 indicates not at all and 4 indicates a great deal. Partners were known a mean of Mean weekly sexual frequency was 2. The close friend CF was someone with whom the participant had a close, positive, interactive but not romantic relationship and was known about as long as the Partner.

Three were siblings, one was a cousin, two were in-laws, nine were friends and two were co-workers. Participants reported a great degree of closeness and friendship to the CF. To further control for familiarity and provide a more direct examination of familiarity effects by comparison with the HFN, the LFN was known ificantly fewer years and was ificantly less close than any of the other targets. Following procedures in Aron et al. Participants were asked to count-back from a high e.

Instructions were provided before and during scanning. All photos were rated for facial attractiveness and image quality by six independent raters three females and three males of around the same age as our participants. Image quality was rated by all six coders, but attractiveness was rated only by coders of the opposite sex as the stimuli. There were no ificant associations of Partner minus HFN coder-rated attractiveness difference scores with neural responses for the Partner vs HFN contrast or of the Partner minus CF coder rated attractiveness difference scores with neural responses for the Partner vs CF contrast.

Thus, it appears that the Partner vs HFN and Partner vs CF activation differences were not due to objective differences in facial attractiveness. The protocol implemented a block de of two min sessions each consisting of six sets of four s tasks in an alternating fashion, followed by stimulus ratings. Each session included two alternating images starting image counterbalanced , interspersed with a count-back task. Duplicating procedures of Aron et al. Participants were instructed to think about experiences with each stimulus person, nonsexual in nature.

To assess whether instructions were followed, at debriefing participants were asked to describe their thoughts and feelings while viewing stimuli. First, anatomical scans were obtained. Next, functional images were obtained. Effects for the stimulus conditions were estimated using box-car regressors convolved with a hemodynamic response function, separately for each participant.

Analyses were carried out using a mixed effects general linear model, with participants as the random-effects factor and conditions as the fixed effect. We placed the region of interest ROI coordinates at the center of the activations reported by studies of early-stage romantic love Bartels and Zeki, ; Aron et al. In addition, we created ROIs based on the peak voxels searched by Aron et al. We adopted an FDR for multiple comparisons correction Genovese et al. The ROIs occupied a 3-mm radius.

Given our a priori hypotheses, and our duplication of methods from Aron et al. Regions of interest activations and deactivations showing responses to images of the Partner vs images of the Highly Familiar acquaintance. ROIs were identified as the highest intensity voxel in a cluster, for the Partner vs highly-familiar, neutral HFN contrast. MNI coordinates x , y , z are at the maximum value for the cluster, which may be elongated in any direction.

P -values P are for false discovery rate FDR correction. Symbols indicate activations overlapping with contrasts to control for closeness and familiarity. Letters indicate origin of regions of interest. In addition, to further examine regions potentially commonly activated for the partner and close friend, the whole-brain t -map for the Partner vs HFN contrast was applied as an inclusive mask for the CF vs LFN contrast, and for the CF vs HFN contrast.

This approach is conservative in that it requires ificant activation for both contrasts. are reported in Supplementary Table S2. We carried out two correlations for the PLS, one with love-related items and one with obsession-related items as suggested by factor analyses of the PLS in long-term relationships Acevedo and Aron, For sexual frequency, we controlled for age by first carrying out a linear regression with sexual frequency as the DV and age as the IV to obtain the residuals. The residuals of sexual frequency controlling for age were then correlated with brain activity. The IOS and relationship length correlations were carried out within the Partner vs CF contrast to control for closeness.

We aimed to replicate some correlation findings Aron et al. The literature origin of each ROI is indicated by a superscript a, b, c, d, e in Table 1. D Image and scatter plot illustrating greater response to the Partner vs HFN in the region of the posterior hippocampus is associated with higher sexual frequency. Thus, as predicted, activations for long-term romantic love were found in mesolimbic, dopamine-rich reward systems. Specifically, we were interested in the VTA, as it has been reported in numerous studies of early-stage romantic love Bartels and Zeki, ; Aron et al.

Regions commonly activated by early-stage romantic love identified in studies and long-term romantic love included the right VTA and posterior caudate body; bilateral anterior caudate body, mid-insula and posterior hippocampus; and left cerebellum. The right amygdala showed deactivation in early-stage love, while the left amygdala showed activation for the long-term love group.

Regions commonly activated by maternal love Bartels and Zeki, ; Strathearn et al. As shown in Table 1 , regions commonly activated by maternal love Bartels and Zeki, ; Strathearn et al. Regions that were similarly activated to the long-term partner using the two control conditions were the VTA, right anterior caudate, left putamen, posterior GP, dorsal Raphe, insular cortex, posterior hippocampus, amygdala, anterior and posterior cingulate.

ROIs were identified as the highest intensity voxel in a cluster, for the Partner vs close friend CF contrast.
