Cognitive Neuroscience Talks
Synchronization and causality between biological oscillations
Synchronization phenomena are often encountered in living nature. The concept of synchronization is widely used in experimental studies and in the modeling of interactions between different physiological subsystems demonstrating oscillatory behavior. The examples range from the modeling of the heart to phase locking of respiration with a mechanical ventilator or with locomotory rhythms, coordinated movement, animal gaits and monitoring depth of anaesthesia. In the first part of the talk the basic methods for synchronization analysis will be presented, while, in the second part the use of these methods will be illustrated on results from a study, where the interactions between heart, respiration and brain waves in humans were investigated during general anaesthesia.
