Aunger cites someone named Juan Delius in an endnote. He calls Delius "a prominent neuroethologist" (page 347). Not familiar with Delius firsthand yet. In this endnote Aunger also references the Hebbian synapse.
For Calvin's work Aunger says "my schematic approach
to replication shares little with Calvin's
sophisticated neuroscientfic approach".
BTW, as you might have read, I've been reading grandpa
Hebb's work on the cell assembly. Doesn't Calvin
fashion himself after Hebb in a way?
All neuromemetic roads will lead back to the problems
Hebb and Lashley grappled with and I'd hope that
someone who calls themselves a neuromemeticist would
address the work of these pioneers adequately, by some
detailed treatment of the original source material.
Lashley's classic "In search of the engram" can be
found in Orbach's _The Neuropsychological Theories of
Lashley and Hebb_. Lashley talks about multiple
representation towards the end of that article and
says, "Somehow, equivalent traces are established
throughout the functional area." He makes an analogy
to wave action and patterns of interference, but his
notion of reduplication is quite curious as it seems
to imply a redundancy of the engram(s). Aunger should
address stuff like this before he dismisses Lashley's
work with the magical wave of a hand and goes on to
talk about the distributed nature of memory. Lashley
was well aware of localization
problems...ummm...that's what he was addressing in his
work! He even has an article exploring electric field
theories via placing gold foil ribbons upon the cortex
of monkeys. Another article addresses evolution of the
mind, oh my!
And if Lashley asked himself about what reduplication
of the memory trace might entail, could the resultant
equivalent traces be considered "replicated" through
the cortex in a sense? That's what multiple
representation implies to me. Maybe Kate could chime
in since representation is her forte.
Just a mutant thought...
