I would agree that temporal coding is often overlooked, but in my opinion, the
most inovative aspect about Cariani's ideas is that he's beginning to look at
all the ways neurons can code information in a parallel way. There's a figure
on his web site entitled "Three complementary types of neural codes" that
speaks to this. I differ with Cariani in that I believe that such coding is
overlapping and simultaneous. Much of the sensory integration that I study is
composed of at least a combination of two of the types listed (time-of-arrival,
spatio-temporal, channel, and latency). I'm currently working on tools to
evaluate temporal pattern coding independent of common stimulus input, so I
can't yet speak to that end.
