I made a Vine taking the same video and manually adding a timer.
   I proved, to my satisfaction, the N400 neurological negative
   spike, as well as a possibility that the P300 is also true. As
   I'm a total amateur in the realm of cognitive psychology (or is
   that computational psychology? I dunno)... I'm fascinated by
   that time-scale, so it was a pleasure to be able to forensically
   analyze my own reaction time. I just... hope I don't have it
   happen again, 'cause I don't like lightening
