“…ac.uk/spm/software/spm8/). The use of a thermoplastic face mask and three-dimensional laser markers enabled us to keep the subjects' heads fixed in the same position during a series of all PET measurements (Ouchi et al, 2006 (Brett et al, 2002)]. The details of this ROI procedure have been reported previously (Tzourio-Mazoyer et al, 2002).…”

Brain ␤-amyloid (A␤) deposition during normal aging is highlighted as an initial pathogenetic event in the development of Alzheimer's disease. Many recent brain imaging studies have focused on areas deactivated during cognitive tasks [the default mode network (DMN), i.e., medial frontal gyrus/anterior cingulate cortex and precuneus/posterior cingulate cortex], where the strength of functional coordination was more or less affected by cerebral A␤ deposits. In the present positron emission tomography study, to investigate whether regional glucose metabolic alterations and A␤ deposits seen in nondemented elderly human subjects (n ϭ 22) are of pathophysiological importance in changes of brain hemodynamic coordination in DMN during normal aging, we measured cerebral glucose metabolism with [18 F]FDG, A␤ deposits with [ 11 C]PIB, and regional cerebral blood flow during control and working memory tasks by H 2 15 O on the same day. Data were analyzed using both region of interest and statistical parametric mapping. Our results indicated that the amount of A␤ deposits was negatively correlated with hemodynamic similarity between medial frontal and medial posterior regions, and the lower similarity was associated with poorer working memory performance. In contrast, brain glucose metabolism was not related to this medial hemodynamic similarity. These findings suggest that traceable A␤ deposition, but not glucose hypometabolism, in the brain plays an important role in occurrence of neuronal discoordination in DMN along with poor working memory in healthy elderly people.

“…Massage brings about a range of psychological and physiological changes including improvements in blood and lymph flow, reduction in muscle tension, increase in pain threshold, improvement of mood, reduction of blood pressure and relaxation of the mind [1][2][3][4][5][6][7]. It is thus used frequently for a range of symptoms including anxiety and stress, back pain and other musculoskeletal conditions [8].…”

“…These functional vascular alterations have led massage researchers to reason that if MT reduces cortisol excretion rates, this will lead to reductions in BP. Several reviews and original investigations have reported decreases in cortisol after subjects have received MT (Ouchi et al, 2006, Field et al, 2005, HernandezReif et al, 2001, Hernandez-Reif et al, 2000, Field et al, 1996, Field et al, 1998, Ironson et al, 1996. It is worth noting, however, that several quantitative reviews have found that MT's mean effect on cortisol is very small or not statistically distinguishable from zero (Moyer et al, 2011, Moraska 2008, Moyer 2004.…”
