Subcallosal Area
The subcallosal area (parolfactory area of Broca) is a small triangular field on the medial surface of the hemisphere in front of the subcallosal gyrus, from which it is separated by the posterior parolfactory sulcus; it is continuous below with the olfactory trigone, and above and in front with the cingulate gyrus; it is limited anteriorly by the anterior parolfactory sulcus. The subcallosal area is also known as "Zuckerkandl's gyrus", for Emil Zuckerkandl. The parahippocampal gyrus, subcallosal area, and cingulate gyrus have been described together as the periarcheocortex. The "subcallosal area" and "parolfactory area" are considered equivalent in BrainInfo, but in Terminologia Anatomica ''Terminologia Anatomica'' is the international standard for human anatomical terminology. It is developed by the Federative International Programme on Anatomical Terminology, a program of the International Federation of Associations of Anatomis ... they are considered distinct structu ...

Rhinencephalon
In animal anatomy, the rhinencephalon (from the Greek, ῥίς, ''rhis'' = "nose", and ἐγκέφαλος, ''enkephalos'' = "brain"), also called the smell-brain or olfactory brain, is a part of the brain involved with smell (i.e. olfaction). It forms the paleocortex and is rudimentary in the human brain. Components The term ''rhinencephalon'' has been used to describe different structures at different points in time. One definition includes the olfactory bulb, olfactory tract, anterior olfactory nucleus, anterior perforated substance, medial olfactory stria, lateral olfactory stria, parts of the amygdala and prepyriform area. Some references classify other areas of the brain related to perception of smell as rhinencephalon, but areas of the human brain that receive fibers strictly from the olfactory bulb are limited to those of the paleopallium. As such, the rhinencephalon includes the olfactory bulb, the olfactory tract, the olfactory tubercle and striae, the anterio ...

Subcallosal Gyrus
The subcallosal gyrus (paraterminal gyrus, peduncle of the corpus callosum) is a narrow lamina on the medial surface of the hemisphere in front of the lamina terminalis, behind the parolfactory area, and below the rostrum of the corpus callosum. It is continuous around the genu of the corpus callosum The corpus callosum ( Latin for "tough body"), also callosal commissure, is a wide, thick nerve tract, consisting of a flat bundle of commissural fibers, beneath the cerebral cortex in the brain. The corpus callosum is only found in placental ... with the indusium griseum. It's also considered a part of limbic system of the brain.

Olfactory Trigone
The olfactory trigone is a small triangular area in front of the anterior perforated substance. Its apex, directed forward, occupies the posterior part of the olfactory sulcus, and is brought into view by throwing back the olfactory tract. It is part of the olfactory system, olfactory pathway.

Cingulate Gyrus
The cingulate cortex is a part of the brain situated in the medial aspect of the cerebral cortex. The cingulate cortex includes the entire cingulate gyrus, which lies immediately above the corpus callosum, and the continuation of this in the cingulate sulcus. The cingulate cortex is usually considered part of the limbic lobe. It receives inputs from the thalamus and the neocortex, and projects to the entorhinal cortex via the cingulum. It is an integral part of the limbic system, which is involved with emotion formation and processing, learning, and memory. The combination of these three functions makes the cingulate gyrus highly influential in linking motivational outcomes to behavior (e.g. a certain action induced a positive emotional response, which results in learning). This role makes the cingulate cortex highly important in disorders such as depression and schizophrenia. It also plays a role in executive function and respiratory control.

Anterior Parolfactory Sulcus
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

Emil Zuckerkandl
Emil Zuckerkandl (1 September 1849 in Győr, Hungary – 28 May 1910 in Vienna, Austria) was a Hungarian anatomist. Biography Zuckerkandl was born in Győr on 1 September 1849, to a Jewish family. He had two brothers: the industrialist Victor Zuckerkandl, and the urologist Otto Zuckerkandl (1861–1921). He was educated at the University of Vienna ( MD, 1874) and was an admiring student of Josef Hyrtl, and an anatomical assistant to Karl von Rokitansky (1804–1878) and Karl Langer (1819–1887). In 1875, he became privatdozent of anatomy at the University of Utrecht, and he was appointed assistant professor at the University of Vienna in 1879, being made professor at Graz in 1882. Beginning in 1888, he was a professor of descriptive and topographical anatomy at the University of Vienna. He conducted research in almost all fields of morphology, making contributions to the normal and pathological anatomy of the nasal cavity, the anatomy of the facial skeleton, bloo ...

Parahippocampal Gyrus
The parahippocampal gyrus (or hippocampal gyrus') is a grey matter cortical region of the brain that surrounds the hippocampus and is part of the limbic system. The region plays an important role in memory encoding and retrieval. It has been involved in some cases of hippocampal sclerosis. Asymmetry has been observed in schizophrenia. Structure The anterior part of the gyrus includes the perirhinal and entorhinal cortices. The term parahippocampal cortex is used to refer to an area that encompasses both the posterior parahippocampal gyrus and the medial portion of the fusiform gyrus. Function Scene recognition The parahippocampal place area (PPA) is a sub-region of the parahippocampal cortex that lies medially in the inferior temporo-occipital cortex. PPA plays an important role in the encoding and recognition of environmental scenes (rather than faces). fMRI studies indicate that this region of the brain becomes highly active when human subjects view topographical scene s ...

BrainInfo
''NeuroNames'' is an integrated nomenclature for structures in the brain and spinal cord of the four species most studied by neuroscientists: human, macaque, rat and mouse. It offers a standard, controlled vocabulary of common names for structures, which is suitable for unambiguous neuroanatomical indexing of information in digital databases. Terms in the standard vocabulary have been selected for ease of pronunciation, mnemonic value, and frequency of use in recent neuroscientific publications. Structures and their relations to each other are defined in terms of the standard vocabulary. Currently NeuroNames contains standard names, synonyms and definitions of some 2,500 neuroanatomical entities. The nomenclature is maintained by the University of Washington and is the core component of a tool called "BrainInfo". BrainInfo helps one identify structures in the brain. One can either search by a structure name or locate the structure in a brain atlas and get information such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terminologia Anatomica
''Terminologia Anatomica'' is the international standard for human anatomical terminology. It is developed by the Federative International Programme on Anatomical Terminology, a program of the International Federation of Associations of Anatomists (IFAA). The second edition was released in 2019 and approved and adopted by the IFAA General Assembly in 2020. ''Terminologia Anatomica'' supersedes the previous standard, ''Nomina Anatomica''. It contains terminology for about 7500 human anatomical structures. Categories of anatomical structures ''Terminologia Anatomica'' is divided into 16 chapters grouped into five parts. The official terms are in Latin. Although equivalent English-language terms are provided, as shown below, only the official Latin terms are used as the basis for creating lists of equivalent terms in other languages.
