Event-related potentials or ERP represent the analysis of brain wave signals related to a particular event. Here, we explain how they work.
Electroencephalography and magnetoencephalography, or EEG and MEG pick up brain wave signals, or neural oscillations. These brain oscillations reflect different brain processes. It is particularly interesting to look at these signals when something triggers the brain. For example, how do the brain waves look like when we give someone a reward? or when they act surprised?
The analysis of brain waves signals at a specific point in time, when a stimulus is presented, are called event related potentials. Each wave, or potential often reflects a distinct brain process. Positive peaks and negative peaks can be observed which are abbreviated with P or N. A number represents at what time the peak occurs.

USE OF STOCK IMAGES AND VIDEOS
Occasionally we make use of stock images and videos (pixabay.com or pexels.com). We use these to make our videos more lively (better than looking at a blank screen). These stock videos should not be taken as an exact scientific reflection of the discussed content. In some cases they are not fully accurate. We try to have a high viewing pleasure, while at the same time create as little confusion as possible. Thus we aim to only use them when it is clear that they are not directly related to the discussed content.
CHANNEL GOALS
The Psyched! channel focuses on providing education about psychology and neuroscience. Here you learn all about human behavior, the mind and the brain. It is our goal to reach everyone, from people who are casually interested to academic researchers. As such we provide simple explanation videos as well as profound lectures.
