The Neural Circuits for Social Bonding: From Infancy to Adulthood
Social bonding, from infancy to death, significantly affects the quality of life. Our nervous system is wired for bonding, with particular wiring diagrams oriented towards the specific bonds that occur between infant and mother, as well as infant and father. Specific brain circuits are activated during social bonding, including friendship and romantic relationships. Breakups with romantic partners, friends, or coworkers are painful, but our neural circuits for social bonding are repurposed and generic for all types of social bonds. There is plasticity within the system, and we can rewire the neural circuits for social bonding in response to experience. Understanding the neural circuits for bonding can help us navigate different types of social bonds, such as introversion, extroversion, trauma bonds, and healthy bonds.
The Importance of Social Bonding for Human Beings
Social bonding is crucial for human beings as they have a unique chemical signature for bonding. Lack of social bonding leads to social isolation which elevates stress hormone levels and triggers aggressive and irritable behavior towards others. Chronic social isolation changes the nature of the brain and body, making social connections more challenging. Healthy craving for social contact has a specific brain circuit and neurochemical signature. Social bonding is critical for maintaining social homeostasis, much like hunger, thirst, and temperature regulation. Seeking social contact is crucial for human beings' well-being, and they put in significant efforts to form social bonds that help them regulate and function optimally.
The neural circuit behind social bonding.
The social homeostasis circuit consists of a detector, control center, effector, and prefrontal cortex, which work together to regulate social bonding. The detector system involves the ACC and the basal lateral amygdala, which help detect healthy and unhealthy social bonds. The control center includes the lateral and peri ventricular hypothalamus, which use hormones like oxytocin to influence social behavior. The effector system drives behavioral responses, such as using social media, texting, or making plans with friends. The prefrontal cortex plays a crucial role in establishing social hierarchies and adjusting them based on subjective understanding. Overall, the neural circuit controlling social homeostasis is highly dynamic and fluid, allowing individuals to maintain and adjust social bonds in different settings with the same people.
The Role of Dopamine in Social Interaction
The dorsal raphe nucleus in the brain contains dopamine neurons responsible for mediating social homeostasis, which is the process by which we crave social interaction when we lack it. Dopamine causes us to seek out social interactions of particular kinds, and chronic social isolation can lead to becoming introverted or even antisocial. This is similar to the hormonal mechanisms that make us hungry when we eat regularly and predict food is coming in. However, just as sudden food deprivation would cause us to seek out food through other routes, sudden social deprivation leads us to crave replacement social interaction.
Understanding the Social Homeostasis Circuit and Dopamine in Introversion and Extroversion
The social homeostasis circuit and dopamine play a crucial role in introversion and extroversion. Introverts release greater dopamine in response to individual social interactions and do not require much social engagement to feel sated. On the other hand, extroverts release less dopamine in response to individual social interactions and require much more social interaction to feel filled up. Therefore, it is useful to think about people in terms of how much social interaction they need to bring the social homeostasis into balance rather than whether they are chatty or quiet. However, the prefrontal cortex affords flexibility in terms of the types of social interactions that one can engage in and whether to spend time with certain people or not.
The Neuroscience of Loneliness and Social Behavior
Loneliness is the distress that arises from differences between ideal and perceived social relationships. Social behavior is motivated by dopamine neurons in the dorsal Rapha nucleus, which causes individuals to seek out social interactions. Similarly, social hunger is likened to hunger caused by a lack of food intake. Those who identify as introverts require fewer social interactions to feel fulfilled than extroverts. Social seeking and social isolation are influenced by where a person sees themselves in the social hierarchy. At a neural level, the same neurochemicals underlie all these different drives. Ultimately, social interactions are crucial for everyone, regardless of their position on the introversion-extroversion spectrum.
The Biological Circuit of Social Interaction and Food Cravings
Social interaction and food cravings share a common biological circuit that is driven by dopamine. Social isolation increases our craving for social interactions, and when we can't fulfill that through social interactions, we turn to other dopamine-boosting activities like eating comfort food. Similarly, food fasting increases hunger and increases our appetite for social interactions. The importance of social interaction in maintaining our wellbeing is comparable to that of basic necessities like food and water. All these homeostatic drives work in synergy, and dopamine is the final pathway that drives our behavior. Falling in love activates the same circuit as social interaction, reducing the craving for other activities like food and sleep, and positively affecting our senses and interpretation of stimuli.
The power of physiological synchronization in social bonding.
Physiological synchronization can enhance social bonding, as proven in a study where people listening to the same story at different times had synchronized heart rates. The quality and perceived depth of social bonds correlate strongly with physiological synchronization between individuals. The body and brain are reciprocally connected so that what we think, hear and feel drives our physiology and vice versa, influencing our state of mind. This can be leveraged, for example, during the holidays to improve relations with challenging family members, avoiding direct confrontation. Instead, engaging in activities that stimulate synchronized physiological responses, such as listening to the same story or attending a concert together, can enhance the sense of bonding between individuals.
The Power of Shared Experiences in Building Stronger Social Bonds
Shared experiences can synchronize heart rates of different individuals, acting as a bridge to establish social bonds. Focusing on external stimuli, such as common narratives, traditions, events, or music that create a physiological response can bond individuals without necessarily shifting their physiologies. The right and left-brained forms of attachment established during childhood also influence adult forms of attachment, underlining the importance of early bonding experiences. Such experiences create subconscious or autonomic nervous system responses that impact adult bonding. Therefore, focusing on creating shared experiences that synchronize physiological responses can establish stronger social bonds. It is a powerful tool for those experiencing challenging interactions or friction in relationships.
The Importance of Autonomic System Synchronization for Healthy Social Bonding in Infants.
Healthy social bonding between infants and their caretakers relies on the synchronization of the autonomic functions of the right and left brain circuits. The right brain system involves emotional regulation, while the left brain system is more conscious and focused on predictable narratives that offer rewards. The physical contact between an infant and their primary caretaker, typically the mother, coordinates and synchronizes the autonomic nervous systems of both parties. Oxytocin, a peptide hormone, plays a key role in this synchronization process. The more closely related one is to the particular child, the more oxytocin is released and the stronger the bond becomes. As children get older, both the right and left brain systems continue to be important in establishing bonds.
The importance of empathy in establishing healthy social bonds.
Establishing healthy social bonds requires both emotional empathy, which is feeling what the other person feels, and cognitive empathy, which is understanding how the other person thinks. Synchronization of bodily and cognitive states are essential for establishing deeper bonds with friends and romantic partners. It is not necessary to agree on everything as disagreements are also a part of bonding. Infants and parents establish healthy bonds using both left and right-brain systems, and as people age, the same circuits established in childhood are repurposed for other forms of attachment. An autonomic bond or synchronization of experience is vital for a complete bond with another individual. Empathy is the ability to sense what others are feeling and thinking, and it forms the foundation of strong social bonds.
The Power of Oxytocin in Social Bonding and Biological Processes.
Oxytocin, a hormone associated with social bonding, is involved in a range of behaviors such as orgasm, social recognition, pair bonding, honesty, and autism. It can be regulated through various pathways, and understanding early forms of attachment can lead to developing healthy adult attachment. Biological processes work on short and long timescales, and while neurotransmitters and neuromodulators are quick, hormones have longer lasting effects. Oxytocin has longstanding effects, such as involving lactation, uterine contraction during childbirth, and sexual response in both males and females. Interactions between individuals that see each other as closely associated release oxytocin at high levels which contributes to social homeostasis.
The Science of Bonding: Exploring the Power of Oxytocin and MTMA.
Oxytocin is a powerful hormone that promotes bonding and connection between individuals. It can be released through physical contact, as well as just the sight or smell of a loved one, and is associated with feelings of trust and sexual desire. MTMA, a drug being explored in clinical trials, can cause massive increases in the amount of oxytocin released, leading to greater feelings of connection and bonding. Oxytocin receptors and gene polymorphisms can also impact an individual's capacity to feel bonded. Some variations in the oxytocin and oxytocin receptor genes have been linked to increased social media interactions, indicating a potential role in social bonding beyond physical contact.
The Role of Oxytocin in Online Social Bonding
The oxytocin system plays a crucial role in online social bonding and can actively encourage more social interactions on social media. Emotional empathy and cognitive empathy together make up robust bonds of various kinds. Introverts and extroverts differ not in how much they seek out social interactions per se, but in how much is enough for the given person. It's important to pay attention to external events, such as narrative story, music, or sports, to drive synchrony of autonomic function for establishing and deepening social bonds. By understanding the biological circuitry of social bonding, individuals can identify entry points to establishing and reinforcing social bonds of different kinds.
The Science of Social Bonding and the Pain of Breaking Up
Breakups, whether between friendships or romantic partners, are painful because they involve a breaking of both emotional and cognitive empathy, causing social isolation and devastation to our nervous system. Social bonding is vitally important to us as a species, and there are specific biological, neurochemical and hormonal underpinnings to it. Understanding these can help us strengthen social bonds and establish new ones. It can also provide insight into why we seek out online interactions and help us work with people we feel challenged in forming social bonds with. While social bonding is complex, it is not infinitely so and is tractable. With this knowledge, we can understand the challenges of breaking up, falling in love, forming attachments, and being challenged with attachments.
