Neuronic Powers are such abilities not known or used widely in the galaxy, it is the ability to operate and manipulate the electrical surge through neurones, without the help of psionic powers, developed by the Punisher Priests of the Cult of the Punishers.
First, they are taught to use it on their own body, to remove the pain in case of a deep wound or amputation, inflicting pain to test their willpower, or boosting their muscles with extra charge, to move faster than the Punisher standards. In the next level, they learn to recognise the electrical identity of their memories occurring inside their brains. Later on, they learn to manipulate them too. In the last level of Neuronic powers, candidates learn how to operate and manipulate an another individual's electrical surge, through skin interaction. They learn how to remove another's pain, and if it is the case of "punishment", they learn how to constantly inflict pain, without letting their victim faint. They learn how to monitor another's thoughts and memories, and if needed, to manipulate them. They learn how to show their own memories to others. It is unknown that if it has ever been needed, but they also learn to manipulate the feelings such as pleasure too.
The Neuronic powers are fascinating, but it is probably the second most dangerous ability to master - first being the Psionic Powers. During training candidate may stop his own heartbeat, crush his internal organs with the pressure inflicted by spasms, break their own bones apart, again, by the pressure inflicted by spasms, manipulate themselves into madness, manipulate themselves into a retard, stopping some or all their brain functions, and all of above to an another individual, in a wrong attempt. And these are but a fraction of what can happen if something goes wrong. It requires focus and hundreds of thousands of hours of training to master it.
