Prediction: the field of consciousness studies, in the 21st century, will be immensely influenced by smarter and smarter ‘brain machines’, by which I mean devices capable of mapping the functioning of the brain and influencing it.
Presently, what we are seeing are fast advances in the field of mapping.
Here is an example of a study that came out in 2010, conducted by Pr Stephanie Ortigue and her colleagues at Syracuse University, Upstate New York.
The topic of the study: falling in love.
“As a scientist I wanted to bring some rationality to the irrational, and to see if love exists in the brain,” said Pr Ortigue.
A good start! As you may know, “bringing objectivity into the field of subjectivity” has been a life-long thread in my own approach to consciousness studies.
The findings: when gazing at a loved one, participants showed brain activity in the dopaminergic subcortical system. Fascinatingly, euphoria-inducing drugs such as cocaine have the same effect. Which leads Ortigue to outline the similarity, as far as brain activity is concerned, between wanting to be with your beloved, and the pull experienced by a cocaine addict toward the drug.
Besides, just like cocaine, being in love was observed to release ‘feel-good’ chemicals such as dopamine, oxytocin (sometimes called the ‘love hormone’), vasopressin and adrenaline. The brain also showed signs of decreased activity in areas related to emotions such as grief, fear and anxiety.
There you go: falling in love is a drug. We all knew that, didn’t we? It’s hard to think of anything more addictive.
And it’s not called love at first sight for nothing. Says Ortigue: “Interestingly we see that primary visual areas are activated in the first milliseconds of visual processing, then higher-order associative brain areas are activated, and then we see a flow of backward activation from these associative brain areas to the primary visual and emotional brain areas.”
The love at first sight effect was observed to stimulate 12 different parts of the brain. Which asks tantalizing questions: how on Earth did they manage to get their subjects into the MRI machine just when they were falling in love? Falling in love, the study suggests, only takes one fifth of a second.
The study used fMRI, a type of brain imaging scan that shows how much blood flows in different areas of the brain, as a localized measurement of brain activity, in respsonse to stimuli such as the face of your loved one, hearing his or her name, and recalling experiences in his or her company.
Stephanie Ortigue concludes, “These findings confirm love has a scientific basis.”
