Protocol Steps
Study design setup
Implement double-blind, placebo-controlled study design with participants randomized to receive either nicotine patch or placebo patch
Note: Double-blind design ensures neither participants nor researchers know treatment assignment
View evidence from paper
“double-blind, placebo-controlled design”
Baseline resting-state fMRI acquisition
Acquire resting-state fMRI signals from cingulate cortex region to establish baseline functional connectivity patterns
Note: Region-specific signals used to extract cingulate functional connectivity

Nicotine or placebo patch administration
Apply single dose nicotine patch (21/35mg) or placebo patch to participant
Note: Single dose administration in double-blind fashion

“Single dose (21/35mg) nicotine patch”
Post-administration resting-state fMRI acquisition
Acquire resting-state fMRI signals following patch administration to measure acute effects on functional connectivity
Note: Timing of post-administration scan not specified in text

“study how nicotine addiction and acute nicotine administration modulate these functional pathways”
Functional connectivity analysis
Analyze correlation between nicotine addiction severity and cingulate resting-state functional connectivity patterns, comparing baseline and post-nicotine conditions
Note: Separate pathways identified for addiction severity versus acute nicotinic action
