Pictures of brain scan study participators of studies about the effect of meditation which show changes in their faces?

Diego Hangartner

Brain scan studies about the effect of mediation seem still be going on since 2004 when they started. Diego Hangartner said on Meditationsszene Schweiz, that he is still participating in such studies for instance with brain scanners, to study the effect of pain, etc. But where can we find the result of these studies? Are they privately funded? Diego Hangartner mentioned to participate in such studies in the U.S. and in Europe. Where these performed in the labs of Richard R. Davidson and the lab of Antoine Lutz in France? And where can we find these results? Are the results not good enough so that it would be worth publishing those, but only the pictures we find in the web?

For instance on the YouTube channel of Landguet Ried we can find a picture of Diego Hangartner as well:

Lama Pema Wangyal

But for instance on the site of the Drukpa Center Kollbrunn we find a picture of Lama Pema Wangyal which has a completely different stile:

Has this something to do, that Diego Hangartner is a brain scan study participator, but eventually not Lama Pema Wangyal?

Alex Gamma

Another potential brain scan study participator about the effect of meditation is Alex Gamma from Switzerland.

On Academia.eu it says about Alex Gamma, that he is:

University of Zurich, Switzerland, Research, Department Member University of Berne, Forensic Psychiatry Service, Post-Doc

and we se a first picture of Alex:

On researchgate.net it is written about Alex:

trained biologist. Neuroscience of drug-induced altered states of consciousness. Neuroimaging, EEG/ERP and subjective experience. Applied statistics in psychiatric epidemiology and clinical psychiatry (ADHD). Philosophy of science: theories of consciousness, evolutionary biology, neurodeterminism, behavioral genetics / heritability, personalized medicine.

And there is a second picture of Alex:

Are these pictures of Alex Gamma from a scientific study about the effect of meditation? And show they a picture when the study started, and wen it ended? Alex Gamma is one of the view people we know in Switzerland which has published papers about meditation, as for instance this paper:

https://www.researchgate.net/publication/353246953_The_Minimal_Phenomenal_Experience_questionnaire_MPE-92M_Towards_a_phenomenological_profile_of_pure_awareness_experiences_in_meditators

But this is not a paper about brain scan studies about the effect of meditation, but at least it is a paper about meditation.
