The medial pallium is the progenitor of the mammalian hippocampus, and is thought to be involved in spatial cognitive mapping and memory formation across a broad range of species. The lateral and ventral pallium is the progenitor of the mammalian piriform cortex, and has an olfactory function in every species in which it has been studied. The ...
This area of the basal ganglia receives input from another area, called the striatum, which has two parts, the caudate nucleus and the putamen. This data is routed to the thalamus, either directly or indirectly. In the case of the interna, one area of the globus pallidus, the structure can feed directly to the thalamus.
The pallium (derived from the Roman pallium or palla, a woolen cloak; pl.: pallia) is an ecclesiastical vestment in the Catholic Church, [n 1] originally peculiar to the pope, but for many centuries bestowed by the Holy See upon metropolitans and primates as a symbol of their conferred jurisdictional authorities, [1] [2] and still remains a ...
Only mammals have a fully developed cortex, but the structure it evolved from, called the pallium, is present in all vertebrates, even the most primitive ones such as the lamprey or hagfish. [182] [183] The pallium is usually divided into three zones: medial, lateral and dorsal. The medial pallium forms the precursor of the hippocampus.
The limbic loop is a functional pathway of the basal ganglia, in which the ventral pallidum is involved. It (and the internal globus pallidus and substantia nigra pars reticulata) receives input from the temporal lobes, and the hippocampus via the ventral striatum.
The basic form of the pallium is a cylindrical layer enclosing fluid-filled ventricles. Around the circumference of the cylinder are four zones, the dorsal pallium, medial pallium, ventral pallium, and lateral pallium, which are thought to be homologous to the neocortex, hippocampus, amygdala, and olfactory cortex, respectively.
Public health experts are warning of a ‘quad-demic’ this winter. Here’s where flu, COVID, RSV, and norovirus are spreading
The nidopallium, meaning nested pallium, is the region of the avian brain that is used mostly for some types of executive functions but also for other higher cognitive tasks. The region was renamed nidopallium in 2002 during the Avian Brain Nomenclature Consortium because the prior name, neostriatum , suggested that the region was used for more ...
