Brain coring is one of the methods Baron Klaus Wulfenbach uses to study the Spark. It consists of selectively destroying areas of a subject's brain until they are no longer sparky. Klaus says he's working hard on the problem of subsequent quality of life.
It is one of the most controversial aspects of Klaus' person. Some believe that either the sparks he chooses to experiment on are all irredeemable criminals, or that the potential good of the study (i.e., finding a way to control the spark in elsewise uncontrollable individuals and thus helping out all of society) outweighs the negative side effects. Others believe that whether or not the sparks were criminals, and whether or not Klaus achieves his goal of understanding (and controlling) the spark, it is simply never ethical to dig into people's skulls.
