The Dreamy State: Hallucinations of Autobiographic Memory Evoked by Temporal Lobe Stimulations and Seizures Vignal et al. (2007)

2. What brain region has the dreamy state been associated with? Which of the following structures are included in the MTL: the temporal cortex, the amygdala, the hippocampus, and/or the basal ganglia?

• The brain region that the dreamy state has been associated with is the mesial temporal lobe (MTL).

• The structures included in the MTL are the hippocampus and amygdala

3. Based on the statistics in Table 3, which brain structure would be the best stimulation target if one wanted to induce the dreamy state (the left amygdala, the right amygdala, the left hippocampus, or the right hippocampus)?

• Based on the statistics in Table 3, the brain structure that would be the best stimulation target if one wanted to induce the dreamy state would be the right amygdala.

4. What emotion is most commonly associated with the dreamy state? Can other emotions be present?

• The emotion most commonly associated with the dreamy state is fear.

• Yes, other emotions like joy, sadness, aggressive behavior, and over-familiarity with the examiner can also be present.

5. What memories are most commonly associated with the dreamy state? Were specific public or historical events frequently reported in the study?

• Visual memories are most commonly associated with the dreamy state.

• Specific public or historical events were never reported in the study.

6. In the study, was the dreamy state provoked by the stimulation of the temporal cortex?

• No, only experiential visual hallucinations were provoked by electrical stimulation of the temporal lobe.
