"The Functional Organisation of the Human Brain derived from 
Resting-State fMRI Time Series"


zum Inhalt:

The Human Brain can be considered as a complex network. Consciousness, 
memory, thought and behaviour become possible because nerve cells are 
organised in a dense web of intricate connectivity, continually 
producing complex patterns on several spatial scales from coherent cell 
populations up to interacting brain regions. Several studies over the 
last decades gave evidence that Cognition mainly exhibits two 
fundamental principles, Functional Segregation and Functional 
Integration, suggesting that the brain's functional network exhibits a 
modular-hierarchical structure. In the presented work, the brain's 
functional network was derived on a macroscopic scale from BOLD-fMRI 
time series, acquired by functional Magnetic Resonance Imaging. The 
recorded time series reflect oxygenation changes in blood vessels that 
are related to neuronal activity. Unfortunately, time series are biased 
by non-neuronal related physiological activity from respiration and 
cardiac pulsation creating the need for an appropriate Pre-Processing. 
The subsequent obtained network possessed a modular structure and graph 
properties that were as well discovered in several real-world-networks.


Alle Interessierten sind im Namen von Prof. Dr. Scheuermann herzlich 
eingeladen.
