After reading Georg and David's proposal I am struck by how many names we will probably agree on. Three terms, hyperstriatum, neostriatum, and archistriatum, cause the most controversy and urgently need changing. Several have suggested replacing misleading names with the letters of those names. A major disadvantage with this approach is that the letters alone have no logic unless they are associated with the inappropriate homologies. They are not distributed alphabetically, and by themselves will be as difficult to learn and remember as the numerical nomenclature for Brodmann's cortical areas. It's likely that new students would learn the misleading names as mnemonics for the new abbreviations, in which case we will not accomplish our goal. If at all possible I prefer to replace names with descriptive terms that retain the original abbreviations. My second choice is to minimally alter names using as much of the original term as is reasonable. And so I would like to offer the following minor modifications of previous suggestions for discussion.
Archistriatum: "Arcipallium" was previously suggested, but ensuing discussions make it clear that we do not yet know enough to include "striatum" or "pallium" as the suffix. However, an appropriate term meaning "arched structure" seems reasonable, especially if it starts with "A". Would Arcos or Arcium be appropriate? Is there someone in our group with a solid Latin/Greek background that can provide the correct term for this?
Wulst, including all parts of the hyperstriatum except HV: Wulst is a reasonable descriptive term that has historical use and no evolutionary biases, so I have no objections to adopting the term. If we do choose to use it, it seems that the word "hyperstriatum" should also be replaced with "Wulst" in the subdivisions of the Wulst, giving WIA, WIS, WA, and WD".
The functional regions V1, S1, and M1 are useful concepts for avian studies, and it's appropriate to recognize the similarities with their mammalian counterparts. It's premature, however, to say that these regions are homologous in mammals and birds without a lot of qualifications about what is meant by "homology".
Neostriatum: Life would be easier if we could find an appropriate term starting with "N". Taking into consideration the suggested term "nidopallium" and the reluctance of some to include "pallium" in the term, I would like to add yet another suggestion of "nidium" (or whatever the appropriate scientific term would be). On consulting my dictionary I found two other Latin root words that might be appropriate: "nodo- or nodu-" - meaning nodus, knot, node. Perhaps one of these is easier to modify into an appropriate scientific term?
