The following video can be a bit disgusting. It shows real human brains and how they are anatomized to analyze their structure even at genomic level.
For me it’s interesting if we can analyze genes and their cooperation in view of producing a mood or emotions. What are the preconditions for an emotion like happiness? Would that be possible? Or does people have to much differences in their genomic preconditions? Or are there any other influencing factors we couldn’t measure (yet)?
