The arbor vitae / ˌ ɑːr b ɔːr ˈ v aɪ t iː / (Latin for "tree of life") is the cerebellar white matter, so called for its branched, tree-like appearance. In some ways it more resembles a fern and is present in both cerebellar hemispheres. [1] It brings sensory and motor information to and from the cerebellum. The arbor vitae is located ...
Dandy Walker malformation is a relatively common congenital brain malformation with a prevalence of 1:30,000 live births. [17] Dandy Walker malformation is characterized by enlarged posterior fossa and in which the cerebellar vermis is completely absent, or present in a rudimentary form, sometimes rotated accompanied by an elevation of the ...
The cerebellum is structured in a similar manner as the cerebrum, with a superficial mantle of cerebellar cortex, deep cerebellar white matter (called the "arbor vitae") and aggregates of grey matter surrounded by deep cerebellar white matter (dentate nucleus, globose nucleus, emboliform nucleus, and fastigial nucleus).
While smoothing can increase the signal-to-noise ratio of the image, it reduces image resolution. [12] [13] Mask: Removes any non-brain areas, such as skull, from the fMRI image. Scale: Scale each voxel so that changes in intensity represent percentage of signal change over the course of the scan. The default sets the mean of each voxel equal ...
Hence, the raw images contain noise from various sources—namely head movements (a scan suitable for morphometry typically takes on the order of 10 min) that can hardly be corrected or modeled, and bias fields (neither of the electromagnetic fields involved is homogeneous across the whole head nor brain) which can be modeled.
The Brain Care Score could help you better care for your brain to prevent dementia and stroke later in life, a new study has found. ... The Good Brigade/Digital Vision/Getty Images.
Embedded within the white matter—which is sometimes called the arbor vitae (tree of life) because of its branched, tree-like appearance in cross-section—are four deep cerebellar nuclei, composed of gray matter. [14] Connecting the cerebellum to different parts of the nervous system are three paired cerebellar peduncles.
This study provides evidence of the genetic influence of the brain structure and size, which are believed to both influence intelligence in some way. Another study in 2006 examined 100 postmortem brains, seeking a relationship between an individual’s Full Scale Wechsler Adult Intelligence Scale score and the volume of their brain regions ...
