Examples of pallial

pallial
They almost always occur at the insertions of the levator and pallial muscles.
In the more laminar pallia of some sharks, medial (hippocampal), dorsal (nonlimbic) and lateral (olfactory) pallial regions can be identified.
In any case, the isocortex may have originated partly as a consequence of an overall "dorsalizing" effect (that is, an expansion of the territories expressing dorsal-specific genes) during pallial development.
A pallial enlargement in evolution may be due to either alteration in genes regulating patterning or growth, or to an increase in the mitogenic activity or number of ingrowing axons.
Briefly, our suggestion is that the mammalian isocortex originated in large part as a consequence of a "dorsalizing" influence in pallial development.
Because the thalamus interacts so extensively with the telencephalon, pallial development across vertebrates is of crucial relevance for understanding it.
Reciprocal projections from pallial regions to dorsal thalamic nuclei are substantially less abundant in sauropsids than they are in mammals.
Furthermore, there is extensive interneuronal migration in tangential direction opposite to that of pallial orientation all across the cerebral wall.
A key issue regarding isocortical evolution is whether a ventral pallial division can be separately distinguished on gene-expression criteria.
Amphibians are thus markedly different from amniotes in terms of both their dorsal thalamic organization and their pallial features.
This mutation could have gathered, in the same neurogenetic territory, cells that express pallial or intermediate territory-related homeotic genes.
For pallial relationships, several major issues are unresolved, one of which is identification of the pallial areas in cyclostomes.
However, different homology hypotheses may imply specific mechanisms of dorsalization (tangential migration, change of identity of ventral pallial cells, or expansion of the dorsal pallium).
In the embryonic mammalian telencephalon, distinct markers for pallial and subpallial regions have been detected.
As for the mammalian diagram, the pallial circuitry is somewhat simplified.
