Psychics have long faced criticism for their claimed abilities to communicate with the dead. In a nationally televised interview Thursday, Theresa Caputo, star of TLC reality series “Long Island Medium,” said she has scientific proof her powers are real.

In a segment on the program "Fox & Friends," Caputo said her brain was scanned in front of a doctor while she “channeled” and alleged the scan showed different activity than other people’s brains. In a video, Caputo is seen wearing a white cap with wires coming out of it, while she promoted her new book, “Good Grief.”

“They did find that I do access a part of my brain that we typically don’t and that my brain actually goes blank,” Caputo said. “It’s almost like it flatlines. Like, it’s clear as I’m channeling.”

The 50-year-old, whose TLC series premiered its new season last month, said she thought everyone could talk to the dead but didn’t realize she was different than others until her late 20s and early 30s.

“I always said that my brain doesn’t work like everyone else’s,” she explained. “I always said since I was a young child, ‘Mom, I don’t feel right. I don’t feel like I belong. I feel different.’”

Though Caputo has been called a fake before, she maintains her work has changed lives.

“You know, everyone is entitled to their own opinion. But you speak to the people that I channeled their loved ones and it has changed their lives in a positive way,” she said.
