Add a definition It is likely that the mammal-like reptiles emerged quite early from the ancestralamniotestock. From theCambridge English Corpus Therefore, theamniotetectorotundal pathway might relay to the telencephalon information on those features that indicate relevancy of visual objects. From theCambridge English Corpus First, the dorsal pallium of stem amniotes acquired sensory inputs from the dorsal thalamus (and descending motor projections). From theCambridge English Corpus Therefore, the similarity between modern reptiles and mammals in the topology of these "cortical" sensory areas may be due to common inheritance from stem amniotes. From theCambridge English Corpus This hypothesis intends to provide a partial account for the major difference in sensory connectivity in the major groups of amniotes. From theCambridge English Corpus In primitive amniotes (subclass anapsida), there are no openings and the roof of the skull is completely covered by bone. From theCambridge English Corpus Synapsid reptiles were the first group of amniotes to be abundant and diversified, and their relations with the presumed ancestral anapsid stock are obscure. From theCambridge English Corpus Their components are noted in the discussion of anamniotes, and the rationale for recognizing them in amniotes is discussed in detail below. From theCambridge English Corpus These projections may have served as precursors for the development of olfactory-hippocampal circuits in amniotes. From theCambridge English Corpus A vomeronasal nerve and system is present in amphibians and most amniotes, whereas in amniotes the lateral line nerves are lost completely. From theCambridge English Corpus Therefore, understanding the origin of the sensory cortices requires analyzing how thalamo-pallial projections evolved during earlyamnioteevolutionary history. From theCambridge English Corpus In the dorsal pallium of amniotes, the degree of similarities at multiple functional levels is also notable. From theCambridge English Corpus These differences have impelled the recurrent suggestion that the functional similarities of the hippocampal and dorsal pallium in amniotes are examples of convergent evolution. From theCambridge English Corpus The basic constituent forebrain neuron populations and their interconnections could have evolved early in vertebrate phylogenesis and, being present in everyamniotegroup, could support the observed common functional characteristics. From theCambridge English Corpus The latter include the extant ray-finned fishes (the actinopterygians) and lobe-finned fishes (the sarcopterygians) including their four-legged descendants (the tetrapods), which comprise amphibians and the amniotes. From theCambridge English Corpus The hypothesis of convergent evolution concerning several functional traits in amniotes might be the most parsimonious alternative if the feature essential for isocortical processing is lamination. From theCambridge English Corpus Amphibians represent an intermediate condition between fishes and amniotes, many of which retain the lateral line system. From theCambridge English Corpus Fitzgerald et al. raises the possibility that increases in choroidal thickness followed by a sharp decline may be age-related phenomena common to many sightedamniotespecies. From theCambridge English Corpus Whether their preglomerularpallial circuitry sufficiently resemblesamniotethalamocortical circuitry and supports this high-level cognitive ability and the working memory-conscious processing that this implies remains to be elucidated. From theCambridge English Corpus These examples are from corpora and from sources on the web.
