Summary
Researchers visualized human brain
Area of Science:
- Neuroscience
- Medical Imaging
- Biophysics
Background:
- Understanding brain connectivity is crucial for neuroscience.
- Brain white matter, composed of axons (nerve fibers), forms key neuronal pathways.
- Axon size (micrometer scale) challenges imaging with conventional X-ray systems.
Purpose of the Study:
- To develop and demonstrate a novel 3D imaging method for visualizing brain white matter structure.
- To reconstruct the orientations of brain fiber connectivity non-invasively.
Main Methods:
- Utilized a grating interferometer setup.
- Employed Anisotropic X-ray Dark-field Tomography (AXDT) for imaging.
- Generated a three-dimensional tomographic reconstruction of neural pathways.
Main Results:
- Successfully reconstructed the orientations of brain fiber connectivity.
- Demonstrated the feasibility of AXDT for microscale neural structure imaging.
- Preclinical survey confirmed the effectiveness of the developed approach.
Conclusions:
- Anisotropic X-ray Dark-field Tomography (AXDT) enables visualization of micrometer-scale neural structures.

26.2K
The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

01:29Dark Triad and Person Perception
302
Person perception is influenced by both external behaviors and the observer’s internal characteristics, including personality traits. Individuals with dark personality traits, comprising psychopathy, Machiavellianism, and narcissism — collectively known as the dark triad – exhibit manipulative and exploitative tendencies in social contexts. These traits affect how they perceive others and how they are perceived.The Role of Dark Personality Traits in Person PerceptionBlack et...

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

01:11Introduction to Connective Tissues
15.0K
Connective tissues are one of the four main tissue types in humans that are extensively present in the body. They are characterized by cells embedded in an extracellular matrix (ECM) composed of a ground substance and three main types of protein fibers— collagen, elastic, and reticular fibers. The ground substance of connective tissues can range from a watery and jelly-like consistency to mineralized and hard. The wide variety of cells in the connective tissues include fibroblasts,...

01:30Classification of Connective Tissues
16.0K
The connective tissues have different properties and functions in the human body. They are broadly categorized into proper, supporting, or fluid connective tissues.
Connective Tissue Proper
Connective tissue proper is the most abundant class of connective tissues. As its name implies, it predominantly connects different tissues in the body. Depending on the cell types, ground substance, viscosity, and fiber types in the ECM, connective tissue proper is further categorized into loose and dense....
