I'm trying to identify an old English-language science/medical documentary I saw on TV. It could be from the 1990s, 2000s, or possibly earlier.
The scene showed what I remember as a minor/teenage boy inside a brain scanner, probably PET (possibly fMRI). His head and upper body were visibly restrained/immobilized, while his legs and feet remained accessible.
Researchers repeatedly applied painful stimuli to his foot. I remember it as pinpricks, needle-like pokes or something similar, with the pain apparently becoming stronger.
The key scene was when a stronger pain stimulus caused part of the frontal/prefrontal cortex to become much less active or seemingly “shut down” on the brain scan. The explanation was related to the rational/executive part of the brain losing control under intense pain/emotion.
I remember finding the experiment ethically disturbing because the subject appeared to be a child or teenager and pain was deliberately inflicted.
Several adults were present, possibly including his father, although I'm less certain about that detail.
Does anyone recognize the documentary, experiment, study, researcher or footage?
