While patient is disassociating (or alters are changing) and music as an independent variable is played and then alternately hummed by patient. There may be similar work in autism literature that displays fMRI as a patient listens versus humming or singing to compare and contrast with brain activity. Please only respond with kind and helpful responses. Please keep all argumentative rhetoric away.
I am not aware of any study that looks at active dissociation. However, please see our paper for further references to imaging work on dissociation and the original study that it describes. Perhaps it would be helpful in your search. Here's reference:

ABSTRACT: Abstract Maternal dissociative symptoms which can be comorbid with interpersonal violence-related post-traumatic stress disorder (IPV-PTSD) have been linked to decreased sensitivity and responsiveness to children's emotional communication. This study examined the influence of dissociation on neural activation independently of IPV-PTSD symptom severity when mothers watch video-stimuli of their children during stressful and non- stressful mother-child interactions. Based on previous observations in related fields we hypothesized that more severe comorbid dissociation in IPV-PTSD would be associated with lower limbic system activation and greater neural activity in regions of the emotion regulation circuit such as the medial prefrontal cortex and dorsolateral prefrontal cortex (dlPFC). Twenty mothers (of children aged 12-42 months), with and without IPV-PTSD watched epochs showing their child during separation and play while undergoing functional magnetic resonance imaging (fMRI). Multiple regression indicated that when mothers diagnosed with IPV-PTSD watched their children during separation compared to play, dissociative symptom severity was indeed linked to lowered activation within the limbic system, while greater IPV-PTSD symptom severity was associated with heightened limbic activity. Concerning emotion regulation areas, there was activation associated to dissociation in the right dlPFC. Our results are likely a neural correlate of affected mothers' reduced capacity for sensitive responsiveness to their young child following exposure to interpersonal stress, situations that are common in day-to-day parenting.
