The context of the target article is delimited again, underlining the
intended location of the argument in the bottom-up hierarchy of brain
study. The central message is that collective delay activity distribut
ions (reverberations) in cortical modules extend the role of a spike (
a potential information carrier across long distances) to an active me
mory of structured, learned information that can be carried across lon
g time intervals. Moreover, the population code of the reverberations
makes them readable down the cortical processing stream. Most of the c
ritical comments are then interpreted and addressed in relation to mis
reading of the proper context. The price for the limitation of the con
text (in cognitive, behavioral, and computational terms) is compared w
ith the advantages of a clear, direct contact with experiment on the o
ne hand and with a well controlled body of modeling and analysis on th
e other.
