The Effects of Smoking Withdrawal On Resting State Functional Connectivity — SmokeAtt04  

Smoking Clinical Trial

Official title:
The Effects of Smoking Withdrawal on Resting State Functional Connectivity

Clinical Trial Summary

The purpose of this study is to see how the brain differs between smoking regularly and after not smoking for 24 hours. The investigators will be using an MRI machine to get the information from adult smokers and non-smokers while they lie in the scanner with their eyes closed. Smokers will be scanned when they have not smoked for 24 hrs and shortly after smoking. It is our hypothesis that brain activity will be altered after not smoking for 24 hours.

Clinical Trial Description

The broad objective of this proposal is to identify functional neuroanatomical correlates of changes in brain functional connectivity during smoking abstinence. The investigators will measure changes in regional blood oxygenation levels using fMRI while adult smokers and non-smokers lie in the scanner with their eyes closed. Smokers will be scanned when they are abstinent from smoking for 24 hrs and shortly after smoking. Our primary hypothesis is that smoking abstinence will alter resting state brain activity (or resting state functional connectivity; RSFC) across widely distributed neural networks and that high-resolution fMRI will help in resolving the exact nature of such changes. Data will be analyzed using methods developed in our laboratory and applied to other resting state datasets. All of the procedures used in the study are well validated and introduce only minor risk to participants (e.g. blood draw; MRI). ;
