I hope this link works. This is what i was referring to in the glove weight /punch power post i made in the mayweather/mcgregor thread. I managed to find the book at my desk and snapped a pic or the page with my phone but there was no way to get it on to the board because it overshoots the limits on attachments. The book was called beyond the ring and it included this graphic and description originally created in a medical journal.

Anyway on page 234 of this book you should be able to see the graphic and description. It describes the type of force and the part of the brain it damages. This journal and the book were published back in the 80's so more has probably been tested on the subjects as the links provided above , show...
