In a first-of-its-kind breakthrough, scientists have discovered a chemical in the brain which is strengthening a person’s social bondage. The brain chemical called Dopamine, which is presented in the body as a neurotransmitter and a herald of other factors including adrenaline is found to be deeply connected with a person’s societal bondage and social relationships. The study carried out by the researchers at the Northwestern University, Evanston, Illinois suggested that the brain chemical Dopamine plays a pivotal role in determining the sociability capacity of a person.

According to the research paper published in the journal Proceedings of the National Academy of Sciences, Dopamine is the brain chemical which influences the bonding and forming of human relationships. The presence of this chemical in the body controls the brains movement, emotions, rewards, and pleasure and it is also responsible for creating sensations, feelings, and emotions connected with them.

For conducting this study, the scientists took 19 duos of babies and their mothers. The aim of the research was to discover some new therapies to treat dopamine-related disorders and syndromes. After analysing the baby-mom pairings, the study found out that there are lots of differences between the behaviour of an infant’s brain and adult’s brain as well as the biological process of a mother’s brain and father’s mind.

The researchers, led by Lisa Feldman Barrett of Northeastern University psychology used a special machine that is capable of conducting two different types of brain scans – functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). By analysing the brain function of the participants through fMRI and PET, the researchers concluded that the brain chemical dopamine is accountable to influence a child’s social activity, behaviour, and relationships with others.

In the brain, dopamine acts as a neurotransmitter – a certain type of chemical emitted by neurones or the nerve cells to transmit the signals to other cells of the brain. The brain has multiple Dopamine pathways, one of which plays a pivotal role in controlling the reward-motivated behaviour of the human being. The insufficiency of dopamine in the brain can escort to Parkinson’s syndrome and make people more vulnerable to addiction, suggested the new study.
