Insights

Diffusion MRI offers insights into brain structure and connectivity. The CONNECT project combined tractography and micro-structural measures for a more accurate brain connectome estimate and validation.

Area of Science:

  • Neuroimaging
  • Neuroscience
  • Biomedical Engineering

Background:

  • Diffusion MRI is crucial for studying living brain tissue morphology, macrostructure, and microstructure.
  • Tractography infers brain connectivity, while advanced frameworks (CHARMED, AxCaliber, ActiveAx) extract micro-structural parameters like axon diameter and density.
  • Understanding brain microstructure and connectivity is vital for neuroscience and disease research.

Purpose of the Study:

  • To combine tractography and micro-structural measures for improved human brain connectome estimation.
  • To extend the validation of diffusion MRI-based micro-structural measurements.
  • To summarize the CONNECT project's efforts and future perspectives.

Main Methods:

  • Utilizing diffusion MRI for non-invasive assessment of brain macrostructure and microstructure.
  • Employing tractography to map structural connectivity between brain regions.
  • Applying advanced diffusion MRI frameworks (CHARMED, AxCaliber, ActiveAx) for micro-structural parameter extraction.

Main Results:

  • The CONNECT project successfully integrated tractography and micro-structural measures.
  • Enhanced estimation of the brain's structural connectome was achieved.
  • Validation of micro-structural measurements was extended.

Conclusions:

  • Combining tractography and micro-structural measures provides a comprehensive view of the brain's connectome.
  • This integrated approach holds significant potential for understanding brain organization and disease.
  • Further validation and application of these techniques are promising for future research.

Coordinates and Map Projections01:29

Coordinates and Map Projections

Coordinates and map projections are essential tools in accurately representing the Earth's surface for various applications, ranging from navigation to spatial analysis. The latitude and longitude coordinate system is a universally recognized framework for defining locations. Latitude specifies the distance of a point north or south of the equator, measured in degrees from 0° at the equator to 90° at the poles. Longitude indicates a location's position east or west of the prime meridian,...

Fischer Projections

Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A Fischer projection is a two-dimensional projection on a planar surface to simplify the three-dimensional wedge–dash representation of molecules. This is especially helpful in the case of molecules with multiple chiral centers that can be difficult to draw. Here, all the bonds of interest are represented as horizontal or vertical lines. While...

Newman Projections

Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as...

Dietary Connections

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...

Introduction to Connective Tissues01:11

Introduction to Connective Tissues

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,...

Classification of Connective Tissues01:30

Classification of Connective Tissues

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....
