Trying gamely to field the topic....

I recall that providing a variable delay to headphones
relaying one's voice is an effective way of invoking stuttering.

I recall that extra-cranial electrodes can provide a signal
with a characteristic delay evoked as a visual response.
 this delay was said to correlate with IQ measures
(a most unPC finding...)

I recall that a group at Lucent/Bell Labs recently reported a
neural net arrangement of a self organizing kind (Kohanen)
that differed from the usual silhouette of feature set clusters,
when they arranged input vector weighting to be unipolar - like
the variable repetition rate characteristic of neuronal activity
is unipolar, in that it can't pulse slower than never!
(rather than the positve and negative values of weights
otherwise allowed)

Sincerely
(from my evil twin...)
