Transcranial magnetic stimulation (TMS) over the motor cortex
When transcranial magnetic stimulation (TMS) is applied over the primary motor cortex, it will induce motor-evoked potentials (MEPs). The magnetic impulse to the motor cortex activates neurons that have connections to muscles throughout the body.
Motor-evoked potentials are often used to measure the excitability of the motor cortex. This is particularly interesting to study in volunteers with movement disabilities, such as after a stroke. Furthermore, the participant in this video is wearing an electroencephalography (EEG) cap, which measures brain oscillations.

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.

Should We Really Trust Our Gut? - The Neuroscience of the Gut-Brain Relationship | Neuroscience 101
zhlédnutí 639Před 9 měsíci
In this episode of Neuroscience 101, we at Psyched! discuss the fascinating relationship between the gut and the brain. Throughout our digestive system, there is a large network of neurons and nerves that allows our brain and gut to communicate with each other. This network of roughly 500-600 million (!) neurons is called the enteric nervous system, and is the largest and most complex neural un...
Predictive Coding: Why Our Brain Is Constantly Predicting The Future
zhlédnutí 4,1KPřed 11 měsíci
Predictive coding is an influential theory in psychology and neuroscience that explains how our brain learns from mistakes. Our brain constantly makes predictions about the future. Then, incoming information (sensory or cognitive) is compared to this prediction. If there is a mismatch between actual information and the prediction, this leads to a prediction error. Prediction errors tell our bra...
Sleep Stages Explained! | Neuroscience 101

Our sleep is characterized by different stages from shallow sleep, to deep sleep, to REM sleep. What happens in the brain during these stages? In this videos we discuss the four sleep stages. The first stage is characterized by oscillatory theta waves which reflect a state of drowsiness. When we just fall a sleep and before we wake up we are in this stage, but most of the night we are in the ot...

The evidence for that is less clear, but most research suggests t...

    • @real.psyched
      @real.psyched Před 17 dny

      The first letter indicates whether a componentvis positive or negative. N meaning negative and P meaning positive. There is however no exact meaning. Whether a component is positive or negative depends on the region and the neural orientation. This will determind the direction of the dipole which in turn causes the electriclal fluctuations on the scalp. I explain this in more detail in the 101 video about EEG.

    I can't understand, it's totally irrational, even after 1 week of seeing nothing, she can't think like have a real reflection on herself adding every clue that she's blind ?? is she a zombie or a robot without any consciousness, just acting with her memories and knowingness how to live normally but without the ability to have a real step back on her situation ? Human are very rational, they are 100% rational every time and even the cognitive bias can be understand by us and we can recognize logically that we have them and stop acting wrong. But that, for my opinion is maybe link with consciousness

(Otherwise, all life on and from this Earth, real and artificial, eventually dies and goes extinct, is ultimately meaningless in the grand scheme of things, and are all a waste of spacetime in this universal existence.) * Mission Impossible of the Highest Order: MIHO. * Nature is our greatest ally in so far as Nature gives us life and a place to live it, AND Nature is also our greatest enemy that is going to take it all away.

      The two motor cortices, left and right, are strongly connected. There are studies that show positive effects on the "weak" side even when targeting the "strong" side. Of course, I do not know the exact protocol and set that is used in your case, so I can't fully judge.

So i showed him & the nurse bring me a piece of paper and a pen. So i wrote "dad please i wanna go home now" .. but my dad couldn't read it neither the nurse. I was sooo angry why they wouldn't understand what i wrote. Like 2 weeks later i was allowed to go home and i found that piece of paper. I just made scratches on it...but 2 weeks before when i wrote it i was 100% sure i wrote sentences. The anton syndrom seems very familiar...

I have TRD and along with that, I deal with constant dizziness (I live off of like 8 motion sickness pills a day.) I'm very treatment resistant when it comes to AD meds but, when they did work, the dizziness was the first thing to go away. (As the meds stopped working, everything came back including the dizziness). All I can think is that maybe my mental issues, are causing me to be more dizzy in some way. Still not really sure how. I'm looking into getting into a clinical trial for VNS so, I hope that clears away the major depression and dizziness!
