What you are describing is a classic example of the SKIN effect at 
work :)  NOT to be confused with voltage. 10:1 the 30kV was at 60Hz.
As frequency rises, current penetration becomes less (inversely 
proportional to square root of the frequency). I don't think nervous 
responses play any part in this.
