Summary
Brain graphs model the human connectome using graph theory. This review guides neuroimaging analysis, focusing on assumptions and trade-offs in studying brain networks.
Area of Science:
- Neuroscience
- Graph Theory
- Network Science
Background:
- Brain graphs abstractly model the human connectome, representing anatomical regions as nodes and connections as edges.
- This approach is increasingly popular for analyzing complex brain structures and functions.
Purpose of the Study:
- To provide a conceptual review and methodological guide for graphical analysis of human neuroimaging data.
- To highlight key assumptions, issues, and trade-offs in brain graph analysis.
Main Methods:
- Utilizing graph theory to define nervous systems as networks of nodes and edges.
- Measuring and comparing topological and geometrical properties of brain graphs.
- Analyzing both structural and functional human brain graphs.
Main Results:
- Human brain graphs consistently exhibit properties like small-worldness, modularity, and heterogeneous degree distributions.
- Brain graphs demonstrate a near-minimization of wiring cost, a significant geometric property.
Conclusions:
- Graphical analysis offers a powerful framework for understanding the human brain connectome.
- Investigators must carefully consider assumptions and trade-offs when applying these methods to neuroimaging data.

Organization of the Brain
The brain is an integral component of the nervous system and serves as the center for processing sensory inputs, making decisions, and directing bodily actions. This complex organ is organized into three primary sections: the hindbrain, midbrain, and forebrain, each responsible for a range of vital functions.
Hindbrain
The hindbrain, located at the base of the brain, plays a vital role in regulating automatic processes that sustain life. It includes the medulla oblongata, which is essential for...

Anatomy of the Brain: Major Regions
The brain is the most complex organ in the human body. It consists of four main parts: the cerebrum, diencephalon, cerebellum, and brainstem.
The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect various areas...

Cerebrum: Anatomical Overview II
Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters thick) made up of gray matter, consisting of neuron cell bodies, dendrites, glial cells, and blood vessels. The middle region, or white matter, is primarily composed of myelinated nerve fibers organized into three types of large tracts: association fibers, commissures, and projection fibers. Association fibers connect different areas within the same...
Brain Imaging
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Neural Circuits
Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

Anatomy of the Brain: Ventricles
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
