Below is Henry Markram's response to my e-mail (exact text). Less blunt, but still tries to mislead. "characteristic pattern" is vague enough that with some plausible interpretations it is not false, but the natural interpretation of "very characteristic pattern" suggests that you can predict connections from one circuit to another pretty accurately, which is false.
From: Henry MarkramTo: Yehouda Harpaz Subject: Re: "precise interconnections" Date: Tue, 01 Apr 2003 12:40:52 +0200 Dear Yehouda, The neocortical microcircuit is constructed with synaptic connections (defined as several synaptic contacts) between neurons exhibiting a very characteristic pattern according to the types of neurons connected. There is also a non-random selection of target cells by any particular cell which is characteristic. So there is clearly a specific plan - just how precise it is we still do not know.
