100mm tubes are longer and require approximately 15-20% more tobacco per cigarette
We included studies in this meta-analysis that: (1) assessed gray matter using structural MRI, (2) reported a set of coordinates (i.e., foci) from a between-subjects contrast comparing smokers to matched nonsmoking participants, (3) reported coordinates in a defined stereotaxic space (i.e., Talairach or Montreal Neurological Institute [MNI]), (4) performed a whole-brain analysis, and (5) provided sufficient information regarding characterization of smoking behaviors (e.g., pack-years, Fagerstrm Test of Nicotine Dependence [FTND] scores, years smoking, number of cigarettes smoked per day), basic demographics of the study samples (e.g., age, sex, N ), and data analysis strategies (e.g., smoothing parameters, statistical thresholds)
Your calculation about 400 puffs in shisha may not be the most accurate way to measure this I think it is not the number of puffs but the much larger volume of smoke that is at issue
Your brain is a hive of activity with billions of neurons processing, storing, and sending information all the time
