Repetitive transcranial magnetic stimulation, or rTMS, can be used to activate or deactive a brain region. But how does it work.
Whereas single pulses of TMS can activate a brain region for a fraction of a second, repetitive TMS pulses can have effects after stimulation has ended. There are several protocol. Conventional rTMS protocols include low frequency rTMS and high frequency rTMS. More recent, patterned rTMS protocols include intermittent theta burst stimulation, or iTBS and continuous theta burst stimulation or cTBS.
Generally high frequency rTMS and iTBS are thought to help neuroplasticity and activate the brain. Low frequency rTMS and cTBS are though to decrease brain activity. However, this should be taken with a grain of salt, since the results of rTMS can be variable. Effects differ between people and can differ from day to day. That is because rTMS effects depend on the current brain state.

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.
