Athos Antoniades is the only martial artist I personally have ever seen post anything regarding training for this sort of thing, and he mentions it only briefly. Check it out and see what you guys think. This is a section of the article he wrote; it's the only place in the article that he really mentions this at all. I posted a link to the article as well so you guys can read the whole thing. This guy teaches a version of Kenpo by the way.

"A subconscious reaction"
Something which I stress in my Kenpo classes, is the fact that fighting is a subconscious reaction. You cannot rely on the conscious thinking part of the brain to see you through a fight as it is too logical and fighting is not a logical process. We therefore train in methods to occupy our conscious mind so that the subconscious can take over.
This is known as the 'no mind' state of mind, or the state of 'doing without doing'. The years of training in our basics teach us mind and body co-ordination. We instinctively become spontaneous masters of adaptability with all our action being both defensive and offensive. The years of solo and two-person training in our techniques, forms, sets and sparring give us the ability to act calmly and spontaneously in a flash when the situation warants it. We will instinctively strike vital targets and Dim Mak points without thinking about it.
At a more advanced level, and certainly not before students have reached brown belt level, I will acquaint them with the 'reptilian brain' which can be thought of as the ultimate 'no mind' state. I have taught about the reptilian brain in the Chinese internal art of Tai Chi Chuan training and have incorporated it into my Kenpo with great success. Kenpo's rapid succession of strikes makes it very adaptable to the reptilian brain.
Humans have three brains inside their heads. The reptilian brain was the first that anything ever had. Reptiles, such as snakes and crocodiles, still only have this brain. Then there is the mammalian brain, which all animals have, and then we, as humans, also have the neo-mammalian or human brain. Humans have all three brains.
The reptilian brain is the survival brain. However, the modern way of life has really made this part of our brain - which modern science has identified as the brain stem - virtually redundant. In order to attain the highest level of martial arts, we must make use of this brain, as it is by nature our survival brain.
By training in both the external and internal arts, we will quite naturally go into this brain in an altercation. By internalising American Kenpo, students will learn to take advantage of this part of their brain. There are certain ways in which we can bring the reptilian brain into action, but this will only be taught to senior students, as it may cause problems if the student has not had an adequate training. Once the reptile brain has come into play, you are in a different world; everything around you seems to move in slow motion.
