Is it possible to quantify the brain potential of each individual? And again, will it be possible, in a not too distant future, to archive an image of one's "connectome" in digital format and upload it to a computer to guarantee ourselves a second life? These are just some of the questions that the study of brain connectivity seeks to answer. Emiliano Santarnecchi is an Italian neuroscientist transplanted to Boston in the USA. Faculty of Neurology at Harvard Medical School in Boston and co-director of the Brain Investigation and Neuromodulation Laboratory at the Faculty of Medicine of the University of Siena, he studies the human “Connectome”, with the aim of mapping the complex network of connections that characterize the human brain. Combining knowledge in the fields of cognitive neuroscience, computational neuroscience and neurophysiology, his studies aim to identify what we could define as a “fingerprint” of the brain of each individual, capable of explaining complex cognitive abilities such as fluid intelligence, as well as predicting the onset of neurodegenerative diseases such as Alzheimer's dementia and guiding rehabilitation programs in subjects affected by cerebral stroke.
