From a paper by Oscar Arias-Carrión, 2008 In an embryonic rat brain, GAD67-binding marker tends to concentrate in subventricular zone. An image from Popp et al., 2009. [1] The subventricular zone (SVZ) is a region situated on the outside wall of each lateral ventricle of the vertebrate brain. [2] It is present in both the embryonic and adult ...
The pathway consists of a para-arterial influx mechanism for CSF driven primarily by arterial pulsation, [2] which "massages" the low-pressure CSF into the denser brain parenchyma, and the CSF flow is regulated during sleep by changes in parenchyma resistance due to expansion and contraction of the extracellular space.
Lung parenchyma showing damage due to large subpleural bullae. Parenchyma (/ p ə ˈ r ɛ ŋ k ɪ m ə /) [1] [2] is the bulk of functional substance in an animal organ or structure such as a tumour. In zoology, it is the tissue that fills the interior of flatworms. In botany, it is some layers in the cross-section of the leaf. [3]

In a multicellular organism, an organ is a collection of tissues joined in a structural unit to serve a common function. [1] In the hierarchy of life, an organ lies between tissue and an organ system. Tissues are formed from same type cells to act together in a function. Tissues of different types combine to form an organ which has a specific ...
The two layers of the dura mater separate at several places, with the meningeal layer projecting deeper into the brain parenchyma forming fibrous septa that compartmentalize the brain tissue. At these sites, the epidural space is wide enough to house the epidural venous sinuses. [2] [4] [5]
Information about the structure and function of the human brain comes from a variety of experimental methods, including animals and humans. Information about brain trauma and stroke has provided information about the function of parts of the brain and the effects of brain damage. Neuroimaging is used to visualise the brain and record brain ...
