Vagus Nerve Stimulation Explained! (VNS/tVNS) | Neuroscience Methods 101

In this video we explaine (transcutaneous) vagus nerve stimulation (VNS/tVNS). The vagus nerve is one of the most crucial nerves of the parasympathetic nervous system. It is involved in contoling heart rate, blood pressure, breathing, digestion, hunger, thirst and much more. It also has been related to affective processing and dysfunction of the vagus nerve has been related to various psychiatric disorders, including depression. Stimulation of the vagus nerve can be done with an implanted device, which is placed inside the chest and directly connects to the vagus nerve. It sends very brief pulses to the vagus nerve. Stimulation consists of several seconds of current pulses, followed by several minutes of no stimulation. Implanted VNS is FDA approved for epilepsy and depression. Stimulation of the vagus nerve can also be achieved non-invasively via transcutaneous vagus nerve stimulation (tVNS). There are two kinds: One stimulates the vagus nerve through the neck, called transcutaneous cervical VNS (ctVNS / tcVNS). The other stimulates the vagus nerve via the auricular branch in the ear. This is known as transcutaneous auricular VNS (taVNS). These non-invasive ways are promising, but more research is required to find the optimal parameters. References: Thompson, S. L., O'Leary, G.

Discussions    / Канал   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.
