Anisotropic diffusion is expected to be increased in areas of high mature axonal order. Conditions where the myelin or the structure of the axon are disrupted, such as trauma, [5] tumors, and inflammation reduce anisotropy, as the barriers are affected by destruction or disorganization. Anisotropy is measured in several ways.
In biochemistry, a Ramachandran plot (also known as a Rama plot, a Ramachandran diagram or a [φ,ψ] plot), originally developed in 1963 by G. N. Ramachandran, C. Ramakrishnan, and V. Sasisekharan, [1] is a way to visualize energetically allowed regions for backbone dihedral angles ( also called as torsional angles , phi and psi angles ) ψ ...
Example of APP immunoreactive neurons (arrow heads) observed in the cortex underneath the impact site (E, G). No APP staining was observed in healthy control animals (D). [23] Axons are normally elastic, but when rapidly stretched they become brittle, and the axonal cytoskeleton can be broken. Misalignment of cytoskeletal elements after stretch ...
The hippocampal formation is a compound structure in the medial temporal lobe of the brain. It forms a c-shaped bulge on the floor of the inferior horn of the lateral ventricle . [ 1 ] Typically, the hippocampal formation is said to included the dentate gyrus , the hippocampus , and the subiculum . [ 2 ]
The five-paragraph essay is a mainstay of high school writing instruction, designed to teach students how to compose a simple thesis and defend it in a methodical, easily graded package.
As an example, biological activity can be expressed quantitatively as the concentration of a substance required to give a certain biological response. Additionally, when physicochemical properties or structures are expressed by numbers, one can find a mathematical relationship, or quantitative structure-activity relationship, between the two.
An example forest plot of five odds ratios (squares, proportional to weights used in meta-analysis), with the summary measure (centre line of diamond) and associated confidence intervals (lateral tips of diamond), and solid vertical line of no effect. Names of (fictional) studies are shown on the left, odds ratios and confidence intervals on ...
In geology, a rock composed of different minerals may be a compositional data point in a sample of rocks; a rock of which 10% is the first mineral, 30% is the second, and the remaining 60% is the third would correspond to the triple [0.1, 0.3, 0.6]. A data set would contain one such triple for each rock in a sample of rocks.
