Thank you for the info. 

I have found during Vipassana meditation, which is mindfulness not imagination, that memory can be simply accessed through focusing one's attention on specific body parts.

(For reference when coming back to this thread: What are the cortical regions?
The cerebrum consists of two cerebral hemispheres the outer layer called the cortex (gray matter) and the inner layer (white matter). There are four lobes in the cortex, the frontal lobe, parietal lobe, temporal lobe, occipital lobe).


Interesting study about emotions. 
Emotions are the glue to everything. They are the chemistry in our body and the energy that contains force-chi-ki and a wealth of information released when we put our focus on it and stuck and causing problems in our body when we hold on to it.

Emotions are on a quantum level energy that is stuck. It feels like pulling invisible energy out of a field that is denser, such as a person's body. 
Various people call that pulling out and connecting to the field various things: Joe Dispenza for example calls it 'Distance Coherence Healing' (https://drjoedispenza.com/pages/coherence-healing).
All it is, is connecting with our hand with the invisible quantum field and 'lighten' it up by pulling out invisible stuck energy (quantum level: from particle to wave). 
It's good fun but also brings up a stuck energy/emotions in oneself.
