Avian Pallium
In the neuroanatomy of animals, an avian pallium is the dorsal telencephalon of a bird's brain. The subpallium is the ventral telencephalon. The pallium of avian species tends to be relatively large, comprising ~75% of the telencephalic volume. Birds have a unique pallial structure known as the hyperpallium, once called the ''hyperstriatum''. A 2002 conference at Duke University (Avian Brain Nomenclature Consortium) established a standard nomenclature for describing the avian pallium as follows: * Pallium ** pyriform cortex ** olfactory bulb ** hippocampus ** corticoid area **hyperpallium *** apicale *** intercalatum *** densocellulare ** mesopallium *** dorsale *** ventrale ** nidopallium *** field L2 *** entopallium *** basorostralis ** arcopallium ** amygdaloid complex *** posterior amygdala *** nucleus taeniae * Subpallium **striatum *** lateral ***medial ** pallidum ***globus pallidus or dorsal pallidum *** ventral pallidum Notable researchers *Stanley Cobb *Onur G ...

Striatum
The striatum, or corpus striatum (also called the striate nucleus), is a nucleus (a cluster of neurons) in the subcortical basal ganglia of the forebrain. The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia. Functionally, the striatum coordinates multiple aspects of cognition, including both motor and action planning, decision-making, motivation, reinforcement, and reward perception. The striatum is made up of the caudate nucleus and the lentiform nucleus. The lentiform nucleus is made up of the larger putamen, and the smaller globus pallidus. Strictly speaking the globus pallidus is part of the striatum. It is common practice, however, to implicitly exclude the globus pallidus when referring to striatal structures. In primates, the striatum is divided into a ventral striatum, and a dorsal striatum, subdivisions that are ...

Posterior Amygdala
Posterior may refer to: * Posterior (anatomy), the end of an organism opposite to its head ** Buttocks, as a euphemism * Posterior horn (other) * Posterior probability, the conditional probability that is assigned when the relevant evidence is taken into account * Posterior tense Relative tense and absolute tense are distinct possible uses of the grammatical category of Grammatical tense, tense.

It is within the boundary of Isle Royale National Park, a national park A national park is a nature park, natural park in use for conservation ( ...

Arcopallium
The arcopallium refers to regions of the avian brain which partially overlap regions homologous to the amygdala of mammals. These regions have formerly been referred to as archistriatum, and before this epistriatum or amygdaloid complex, and a recent change of nomenclature has divided the region into the arcopallium and posterior pallial amygdala. The new nomenclature, adopted in 2004, reflects a modern understanding that the avian brain is broadly similar to the mammalian brain, containing large regions homologous to the mammalian neocortex The neocortex, also called the neopallium, isocortex, or the six-layered cortex, is a set of layers of the mammalian cerebral cortex involved in higher-order brain functions such as sensory perception, cognition, generation of motor commands, sp ..., claustrum, and pallial amygdala. The outdated nomenclature it replaced perceived the avian brain as consisting almost entirely of enlarged basal ganglia, to which more complex outer l ...

Nidopallium
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 primitive functions as the neostriatum in mammalian brains is sub-cortical. Anatomy The avian nidopallium is an area of the cortical telencephalon of the avian forebrain, and is itself subdivided into smaller regions as a result of further functional localisation. It has been apportioned along the rostrocaudal (anteroposterior) axis into three hypothetical segments: the rostral, intermediate and caudal nidopallium. These three regions are themselves trichotomised: the caudal nidopallium, for example, aggregates the nidopallium caudocentral (NCC), caudomedial (NCM) and caudolateral (NCL). It is the nidopallium caudolaterale which is though ...
