Psychobiology of altered states of consciousness.

Symptom provocation and reduction in patients suffering from spider phobia
TLDR
It is concluded that successful treatment of spider phobia is primarily accompanied by functional changes of the medial OFC, which is crucial for the self-regulation of emotions and the relearning of stimulus-reinforcement associations.
