Traditionally, the heart region was always associated with emotions and feelings in humans. But in one recent philosophy lecture I watched on Youtube, the orator said that the right brain is, in fact, the origin of emotions and the heart is just for pumping the blood.
In Yoga and many other traditional Eastern disciplines, the Chakra Theory is quite prevalent and the Anahata or the Heart chakra/meridian is quite strongly associated with emotions.
What is the stance of modern medical science on this? Can the source of all emotions be explained completely in the right hemisphere of the brain through neuroscience? Or is there any scientific backing for the linkage of Heart to emotions? Or such a discovery might be possible in future?
