6. There was a strong connection between the PCC (posterior cingulate cortex) and the BDS (bilateral dorsal striatum) - r=+0.5, and the BI (bilateral insula) - r=+0.6, which demonstrates a significant positive correlation. What does this suggest?
The longer the participant had been addicted, the stronger these connections were
The longer the participant had been addicted, the weaker these connections were
7. Could this study be generalised?
No - only Chinese women were used
No - only Chinese men were used
No - only British women were used
Yes - a variety of ethnicity and genders were used
8. What type of scanner was used?
fMRI Scan
CAT Scan
PET Scan
9. Where were the sample recruited from?
Rehabilitation centre in China
Rehabilitation centre in England
Hospital in China
Hospital in England
10. Was there any interference when scanning?
No - only focused on a 6mm point of interest, no 'noise' from nearby areas of the brain were registered
Yes - other areas were registered
11. What is the function of the posterior cingulate cortex?
Allows you to make rational decisions
Reward, motivation and control
Controls aggression and anger
12. There was more activity between the PCC (posterior cingulate cortex) and bilateral insula in drug users. What does this suggest?
Drug users respond to pictures of drugs with a feeling of craving, whereas non-drug users don't, as they don't crave the substance
Drug users allow themselves to be rewarded more frequently
Drug users become more aggressive than non-drug users
13. What is the bilateral dorsal striatum responsible for?
Reward System
Controls anger and aggression
Associating emotional feelings with decision making
14. Each participant underwent a ... followed by a ...
resting state fMRI scan ... heroin-cue fMRI scan
resting state CAT scan ... heroin-cue CAT scan
resting state PET scan ... cocaine-cue PET scan
resting state fMRI scan ... cocaine-cue fMRI scan
15. Was the ethical guideline of 'Protection of participants' broken?
Yes - by showing drug addicts tempting pictures, may have increased the likelihood of going back to drugs
