Thank you, Mr. Chair.
I'm reading right now the discussion part of the study, and I would like Dr. Smith to comment on it. It says as follows:
This study examined BOLD fMRI response among regular current marijuana users and nonusers during a Go/No-Go task. Although differences in behavioral performance were non-significant, the two groups differed in their pattern of neural activation....
Can you comment on the reasons that the differences in behaviour performance were non-significant?
