Stony Brook University researchers looked at the brains of Bernstein and 16 other people who had been married an average of 20 years and claimed to be still intensely in love. They found that their MRIs showed activity in the same regions of the brain as those who had just fallen in love.
“It’s always been assumed that passionate love inevitably declines over time,” said Arthur Aron, a social psychologist at Stony Brook University and one of four authors of the study, presented in November at the Society for Neuroscience annual meeting in Washington, D.C.
“But in survey after survey we always have these people who have been together a long time and say they are intensely in love. It was always chalked up to self-deception or trying to make a good impression,” he said.
This study suggests that’s not the case, said Bianca Acevedo.
