In neuroscience, tractography is a 3D modeling technique used to visually represent nerve tracts using data collected by diffusion MRI. [1] It uses special techniques of magnetic resonance imaging (MRI) and computer-based diffusion MRI.
If the large sample approximation is used (and not the exact distribution), b is required to be "large". The blocks were randomly selected from the population of all possible blocks. The outcomes of the treatments can be coded as binary responses (i.e., a "0" or "1") in a way that is common to all treatments within each block.
Free response tests are a relatively effective test of higher-level reasoning, as the format requires test-takers to provide more of their reasoning in the answer than multiple choice questions. [4] Students, however, report higher levels of anxiety when taking essay questions as compared to short-response or multiple choice exams. [5]
Neuroimaging is the use of quantitative (computational) techniques to study the structure and function of the central nervous system, developed as an objective way of scientifically studying the healthy human brain in a non-invasive manner.
The documents contained in the document-based questions are rarely familiar texts (for example, the Emancipation Proclamation and Declaration of Independence are not likely to be on a U.S. history test), though the documents' authors may be major historical figures. The documents vary in length and format.
Computational neuroscience (also known as theoretical neuroscience or mathematical neuroscience) is a branch of neuroscience which employs mathematics, computer science, theoretical analysis and abstractions of the brain to understand the principles that govern the development, structure, physiology and cognitive abilities of the nervous system.
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 ...
Deviations from a straight line suggest departures from normality. The plotting can be manually performed by using a special graph paper, called normal probability paper. With modern computers normal plots are commonly made with software. The normal probability plot is a special case of the Q–Q probability plot for a normal distribution.
