□EEG in sleep studies gives us information of sleep architecture□ □Video-EEG/Stereo-EEG is used for "catching up" and examining seizures and can be quite a long (days/weeks) study. Non-urgent EEG-study can also be part of another study (PET-EEG, TMS-EEG) and it is also used when examining the function of the optic nerve located in the brain (VEP). □ Non-urgent EEG-studies are done at an outpatient clinic with an appointment. ❗️Urgent EEGs are done for example in the Emergency Room, department of neurology or intensive care unit (adult and neonatal). Electrodes can also be implanted into the brain, when examining possibilities for epilepsy surgery.ĭuring the years I have involved with different types of EEGs in urgent and non-urgent cases: This is the most common way of performing EEG-study. □EEG can be measured with electrodes placed on the scalp surface. It would be the most entertaining study for technicians, if thoughts could be read. □People, who are having an EEG-study, often ask "Can you see what I am thinking right now"? From behind of the screen where EEG-waves are "running", I unfortunately have to say that this device can't read your mind. For me, EEG-studies, which I have done for newborns, have affected me the most. ❤️There's always the person and the story behind the EEG-study, for example elderly person found at home unconscious and brought to the hospital, a newborn with suspected seizures, a toddler with suspicious fallings, just to mention a few. It is usually needed when diagnosing brain disorders, especially epilepsy, but also in other situations like head injuries, headaches, dizziness, brain tumors and sleep problems. □EEG (electroencephalography) is a technique used to measure the electrical activity of the brain. #BCI #EEG #gtecmedical #braincomputerinterface #ghisys #gtecsuite2020ĮEG: One of the main tools in my tool kit Great to use Simulink for such visualizations, because it is very flexible. We created the video with g.HIsys sending data to g.SCOPE (right) and into a Simulink scope (left) at the same time. This makes it easy to interpret alpha, beta, delta, theta, power line ✅ The video on the right shows that the simple rules are correctly done:ġ) The data scope updates from left to right and gives a stable visualization.Ģ) All channels are scaled with +/-100 µV -> this makes a comparison between channels very easy! EEG channels next to each other must look pretty similar.ģ) The raw data keeps visible on the screen for 6-8 seconds. For some channels it is even impossible to determine what's EEG or just noise. ❌❌ Even worse is that the signal is auto-scaled and therefore channels cannot be compared to each other. ❌ The video on the left side shows signals that update from right to left and this keeps the signal flowing all the time and makes it really difficult to interpret what we are seeing. What is your worst ever opponent player (leader of the player statistics) in your sleep game?ĭid you know that EEG data visualization is done in two different ways □□? It has a strong impact on data quality and on how neurologists will see us ⁉️⁉️. If I try to play a dirty game (like blocking the Cat), I get a 2 minute penalty (Relaxed Mind goes to the penalty box). If I have an injured player (for example the goalie is sick), I have a penalty kill all night. Player: the Cat (leader of the player statistics)Įvery night when I sleep, I have a game. Player is the goalie: Arousal (a phenomenon in EEG when sleep breaks)Ģ. My worst case scenario opponent is a team built like this:ġ. Player is the goalie: Spindels (a phenomenon seen in EEG when sleeping) Then there is the opponent's team, which tries to ruin your sleep in every possible way.ġ. You have your hockey team, and its goal is to catch as many sleep cycles as possible (score). One night, when I was at work monitoring ongoing sleep studies, I realized that sleeping is like an ice-hockey game.
