“This was the biggest shock of my life,” says Miguel Nicolelis about denialism on social media.

This Monday's Roda Viva (28) welcomes doctor and neuroscientist Miguel Nicolelis .
During the episode, host Vera Magalhães questions the scientist about current polarizing and even denialist trends, particularly those influenced by social media . She also addresses topics previously considered consensual, such as the importance of vaccination .
The neuroscientist comments that the culture of admiration for science has been shattered and highlights his shock at the attacks he has received on social media regarding the topic.
"When the vaccine came out, that was the biggest shock of my life. When we went on television saying, 'Look, people need to get vaccinated,' I started getting messages like, 'The vaccines coming from the United States have a microchip inside that will monitor you, and you work in this field, you know it's your microchip that's there.'" It was kind of scary. And it just got worse," he says.
Still on the program, Nicolelis responds to CBN Radio journalist Petria Chaves about the concept of an informational virus, which he defines as a set of fake news that “ infects” the brains of many people through very fast communication .
"This is my definition of an information virus : it's a packet of false information, or fake news , that infects the brains of millions of people through lightning-fast communication and creates a brainnet . But it creates a brainnet that propagates conspiracy theories , nonsense like the ones I just mentioned. And it synchronizes."
As an example of this "synchrony," the neuroscientist cites the United States, where a large portion of the population doesn't believe in scientific data, not even what's broadcast live on television. "This creates a whole chain of fake news ," he adds.
