[Anterior prefrontal cortex and serotonergic system activation during Zen meditation practice induces negative mood improvement and increased alpha band in EEG].

Rinsho shinkeigaku = Clinical neurology January 1, 2012 Hideho Arita

In 15 healthy volunteers, a 20-minute session of abdominal (Tanden) breathing increased oxygenated hemoglobin in the anterior prefrontal cortex, reduced negative mood, and altered brainwave activity: alpha band activity increased while theta band activity decreased. These EEG changes correlated with a rise in whole blood serotonin (5-HT) levels. The findings suggest that activation of the anterior prefrontal cortex and the serotonin system may underlie the mood improvements and EEG changes observed during Tanden breathing.

Activation of the anterior prefrontal cortex and serotonergic system is associated with improvements in mood and EEG changes induced by Zen meditation practice in novices.

Focused attention on lower-abdomen breathing (Tanden) for 20 minutes increased oxygenated hemoglobin in the anterior prefrontal cortex, a region linked to attention, in 15 healthy novices. This was accompanied by reduced negative mood, increased alpha brainwave activity, decreased theta activity, and a rise in whole blood serotonin levels. The findings suggest that activation of the prefrontal cortex and serotonin system may underlie the mood improvements and EEG changes observed during this form of Zen meditation.
