Brain Connectivity

Magnetoencephalography (MEG) and Electroencephalography (EEG)

The Human Connectome Project uses Magnetoencephalography (MEG) and Electroencephalography (EEG) to study the brain’s electrical and magnetic activity. These techniques give us deep insights into how the brain’s networks talk to each other in real-time.

Principles of MEG and EEG

MEG tracks the magnetic fields from the brain’s electrical activity. EEG measures the electrical signals on the scalp. Both methods give us detailed information about the brain’s workings in real-time.

When combined with other neuroimaging data, we get a full picture of the brain’s complex networks.

Acquisition of MEG/EEG Data

The Human Connectome Project uses top-notch MEG and EEG setups to get high-quality data. For instance, Saint Louis University’s MEG facility has 248 magnetometers and 64 EEG channels. It captures signals from less than 1 Hz to over 100 Hz.

This range gives us detailed information on how information moves through the brain. The resolution of MEG/EEG is about 1–2 cm, which helps us understand brain activity patterns.

Even with some limitations, the data from the Human Connectome Project helps us see how brain activity is inherited. It also sheds light on how cognitive networks work together.

By using MEG, EEG, and other neuroimaging tools, the Human Connectome Project aims to fully map the brain’s wiring and how it works. This will help us understand human brain connectivity better, benefiting neuroscience research and clinical practices.

Computational Methods and Analysis

The Human Connectome Project generates a lot of data. To handle this, researchers use advanced methods and analysis. They use tractography to map the brain’s fibers from imaging data. This helps us see and understand the brain’s connections.

Fiber clustering groups these fibers, making it easier to see the brain’s structure. This is key for understanding how the brain works.

Researchers also use network analysis to study the brain’s networks. This helps us learn about the brain’s complex structure and function. These methods are vital for discovering the brain’s connections and patterns.

Tractography and Fiber Clustering

Diffusion imaging data lets researchers create detailed maps of the brain’s fibers. Tractography algorithms trace these fibers, showing how the brain connects. Fiber clustering then groups these fibers, making the brain’s wiring clearer.

Brain Network Analysis

The project also looks at how different brain areas talk to each other. This is done through resting-state fMRI and MEG/EEG. Brain network analysis helps us understand how these networks work together.

“The Human Connectome Project has set a new standard in neuroimaging research, with the potential to influence future studies in human brain mapping and disease research.”
