- Brain areas implicated in Conversion disorder
- Inhibition in primary somato-sensory regions
- Affected and Unaffected limb experiment
- Indicates active suppression of responses to other parts of the brain
- Affected and Unaffected limb experiment
- Increased activity in dorsolateral prefrontal cortex
- Decreased hippocampal activity
- Increased activity in frontal cortical regions (inferior frontal gyrus)
- Freudian suppression of emotion tasks
- Suggests suppression of emotion during no-think trials
- Freudian suppression of emotion tasks
- Decreased amygdala activity
- Freudian suppression of emotion tasks
- Suggests suppression of emotion during no-think trials
- Freudian suppression of emotion tasks
- Distressing account tasks
- Distressing emotional accounts tasks
- Indicates suppression of traumatic memories
- ALSO indicates emotional dis-inhibition of anxiety
- Indicates suppression of traumatic memories
- Mental representation of body part studies
- Temporo-parietal junction and supplementary motor area increased activity
- Stimulation of right temporo-parietal junction and OBE reseach
- Lack of proprioceptive feedback leads to the perception that the conversion movement is not self generated
- Indicates highly abnormal mental representations of body parts affected by the disorder
- Temporo-parietal junction and supplementary motor area increased activity
- Persuasive-ness tasks
- Temporo-parietal junction and supplementary motor area increased activity
- Stimulation of right temporo-parietal junction and OBE reseach
- Lack of proprioceptive feedback leads to the perception that the conversion movement is not self generated
- Highlights the importance of the TP junction in conceptualising other peoples mental states
- Temporo-parietal junction and supplementary motor area increased activity
- Inhibition in primary somato-sensory regions
