BOOK REVIEW | Mirroring People: The New Science of How We Connect With Others
Review by Amy Maxmen
By Science News
People cry when they watch sad movies or wince when they see athletes fall. This sense of shared experience is thought to be at the core of human society. How empathy physically happens, however, wasn’t known until neuroscientists in Italy stumbled upon a possible explanation 15 years ago.

Iacoboni, one of those pioneers at the University of Parma, describes how he and his colleagues initially sought to find which neurons fired when a monkey moved its hands. They attached tiny electrodes to individual cells in the monkeys’ brains, and the monitor buzzed when the monkeys snatched a peanut. Yet once when a lab assistant was preparing for the experiment and moving around peanuts, the neurons in the wired-up monkey began to fire — the same neurons that fired when the monkey itself picked up the peanuts.
More experiments confirmed that a set of neurons fired both when monkeys performed an action and when they saw the action performed. The team named the cells mirror neurons, and studies have since extended to humans.
