TABLE 7.
New Terminology for Telencephalic Fiber Tracts and Intratelencephalic Boundaries
| Structure and Karten-Hodos (or other) term for structure (abbreviation) | Latin name adopted by Forum (abbreviation) | English name adopted by Forum (abbreviation) | Comments | Refs. pertinent to the new name |
|---|---|---|---|---|
| Intratelencephalic lamina and boundaries | ||||
| Lamina medullaris dorsalis (LMD) | Lamina pallio-subpallialis (LPS) | Pallial-subpallial lamina (PSL) | Change to a clear descriptive name | Puelles et al., 2000 |
| Lamina archistriatalis dorsalis in Zeier and Karten, 1971 (LAD) | Lamina arcopallialis dorsalis (LAD) | Dorsal arcopallial lamina (LAD) | Abbreviation retained if Latin used | Zeier and Karten, 1971 Kuenzel and Masson, 1988 |
| Lamina hyperstriatica (LH) | Lamina mesopallialis (LaM) | Mesopallial lamina (LaM) | Change needed since region above lamina now the mesopallium | |
| Lamina frontalis superior (LFS) | Lamina frontalis superior (LFS) | Superior frontal lamina (SFL) | No reason to change | |
| Lamina frontalis suprema (LFM) | Lamina frontalis suprema (LFM) | Supreme frontal lamina (MFL) | No reason to change | |
| Telencephalic fiber tracts | ||||
| Tractus thalamostriaticus (TTS) | Tractus thalamopallialis (TTP) | Thalamopallial tract (TTP) | Changed because pallial structures are targets of tract | Karten and Hodos, 1970 Karten et al., 1973 Gamlin and Cohen, 1986 |
| Tractus archistriatalis dorsalis (DA) | Tractus dorso-arcopallialis (DA) | Dorsal arcopallial tract (DA) | Abbreviation retained | |
| Tractus fronto-archistriatalis (FA) | Tractus fronto-arcopallialis (FA) | Fronto-arcopallial tract (FA) | Abbreviation retained | |
| Tractus septomesencephalicus (TSM) | Tractus septopallio-mesencephalicus (TSM) | Septopallio-mesencephalic tract (TSM) | Not of purely septal origin; abbreviation retained with Latin term | Karten et al., 1973 Reiner and Karten, 1983 Wild and Williams, 2000 |
| Tractus occipitomesencephalicus (OM) | Tractus occipito-mesencephalicus (OM) | Occipito-mesencephalic tract (OM) | No reason to change | Zeier and Karten, 1971 |
| Tractus occipito-mesencephalicus, pars hypothalami in Zeier and Karten, 1971 (HOM) | Tractus occipito-mesencephalicus, pars hypothalamica (HOM) | Hypothalamic part of Occipitomesencephalic tract (HOM) | No reason to change | Zeier and Karten, 1971 |
Summary of the nomenclature recommendations of the Forum for major cell free lamina and fiber bundles of the telencephalon in birds. For each structure considered, the first column of the table shows the original name assigned (typically from Karten and Hodos, 1967) and the original abbreviation, the next column shows the Latin variant and abbreviation of the new (or carried over) term recommended by the Forum, the next shows the English variant and abbreviation of the new (or carried over) recommended term, and the final two columns present any noteworthy comments about the change and key references pertinent to the change
