Pure Autonomic Failure
Chapter 4 endnote 55, from Lisa Feldman Barrett.
Some context is:
Patients with spinal cord damage or Pure Autonomic Failure, a degenerative disease of the autonomic nervous system, have interoceptive predictions but don’t receive sensory inputs from their organs and tissue. These patients likely experience affect based primarily on uncorrected predictions.
Patients with pure autonomic failure have impaired body budgeting (selectively in the autonomic nervous system, or "ANS"), meaning their bodies cannot send ANS prediction errors to the brain. Also they have difficulty mounting heart rate and blood pressure changes during exercise and tasks that require effort, such as doing math problems in their heads. All indications are that these patients have normal affect; or if they have impairments, they are very, very subtle. A brain imaging study indicates that they still have increased activation in body-budgeting brain areas that issue predictions and therefore their interoceptive perceptions and associated affective feelings are based primarily on interoceptive predictions.
