In the classic Oddball paradigm, two types of stimuli affecting the same sensory channel are presented randomly within an experiment, with a significant difference in the probability of occurrence. The more frequently occurring stimulus is called the standard stimulus, which serves as the background of the entire experiment; the less frequent ...
The participants in the experimental group were connected before the start of the experiment to an apparatus which allegedly recorded their heartbeat. [2] At the same time, the subjects received the feigned feedback of their heartbeat rate via headphones. However, the distorted heart rhythm recorded via headphones was not his own. The ...
By adding the fluid surrounding the first heart to the second heart, he caused the heart rate of the second heart to slow down. This proved that stimulation of the vagus nerve caused the release of a substance which acted upon the heart tissue and directly caused the heart rate to slow down. (Figure 2) This substance was called vagusstoff.

Heart rate variability visualized with R-R interval changes Electrocardiogram (ECG) recording of a canine heart that illustrates beat-to-beat variability in R–R interval (top) and heart rate (bottom). Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the ...
