I was unclear. My comment was just a tongue in cheek way of saying: it's not odd that we don't have much electrophysiological knowledge of single human neurons because of the practical and ethical problems that come with brain slice electrophysiology on humans -- you need live tissue which is hard to get.

What you've linked to deals with "in vivo" rather than brain slice ("in vitro") electrophysiology, which in humans would encounter the same issues. Cool techniques though nonetheless.
