Add a definition This may indeed represent one of the events that triggered the great development of the dorsalpalliumand associated structures in the mammalian radiation. From theCambridge English Corpus The exclusive presence of a six-layered cortex in the dorsalpalliumof mammals and its enormous expansion during evolution has long intrigued many scientists. From theCambridge English Corpus Thus, alterations in different genes have distinct effects on thepallium, which may help to explain the different models found in vertebrates. From theCambridge English Corpus First, the dorsalpalliumof stem amniotes acquired sensory inputs from the dorsal thalamus (and descending motor projections). From theCambridge English Corpus Because the visual cortices of synapsids and sauropsids derive from different portions of the dorsalpallium, they cannot be homologous as visual cortices. From theCambridge English Corpus This model requires an invasion of collothalamic projections into the lateral part of the dorsalpallium. From theCambridge English Corpus We are certainly in agreement with these proposals, especially considering that these associative networks may have been widespread in the early mammalian dorsalpallium. From theCambridge English Corpus The dorsal thalamus projects bilaterally to the medialpalliumand receives an ipsilateral reciprocal projection back from it. From theCambridge English Corpus As discussed in the target article such a tangential migration, if it exists, might be a consequence of a dorsalizing influence over the ventralpallium. From theCambridge English Corpus The small dorsalpalliumin amphibians is likely to be homologous to the dorsal cortex of reptiles and the hyperpallium of birds. From theCambridge English Corpus This possibility is certainly consistent with the concept of a dorsalizedpalliumin mammals with respect to reptiles. From theCambridge English Corpus Unfortunately, at this point there is no evidence indicative of a migratory process from the ventralpalliuminto the dorsalpallium. From theCambridge English Corpus However, different homology hypotheses may imply specific mechanisms of dorsalization (tangential migration, change of identity of ventral pallial cells, or expansion of the dorsalpallium). From theCambridge English Corpus Therefore, the confluence of lemnothalamic and collothalamic pathways in the dorsalpalliumis not an innovation of mammalian brains, as postulated in the target article. From theCambridge English Corpus Another interesting aspect in isocortical evolution is the correlation between an enlargement in the dorsalpalliumand a parallel enlargement in the dorsal thalamus. From theCambridge English Corpus The development of visualolfactory associative networks involving the hippocampus may have a favored selection of an expanded dorsalpallium. From theCambridge English Corpus In this case, the most likely candidate for homology with the isocortex is the reptilian dorsal cortex, which derives from the dorsalpallium.
