When we talk about measuring brain activity in hospitals, it's important to know the difference between two kinds of techniques: invasive and non-invasive.
Invasive Techniques are those that go inside the body. Here are two examples:
Intracranial EEG (iEEG): This involves placing small sensors directly on the brain. This gives very detailed information about how the brain is working. It is often used when doctors are preparing for epilepsy surgery.
Depth Electrodes: These are devices that are put into specific parts of the brain. They help doctors learn about areas of the brain that cannot be seen from the surface.
Advantages: These invasive methods can find brain activity very accurately and quickly.
Disadvantages: However, they can be risky. There is a chance of infection, and they need surgery, which means they are only used in certain situations.
On the other hand, we have Non-Invasive Techniques. These methods are safer and easier to do. Here are two examples:
EEG (Electroencephalography): This technique records brain activity from sensors placed on the scalp. It's commonly used for diagnosing conditions like epilepsy and sleep problems.
fMRI (Functional Magnetic Resonance Imaging): This method looks at changes in blood flow to understand brain activity. It is great for figuring out how different parts of the brain work together before surgery.
Advantages: Non-invasive techniques are safer and more comfortable for patients. They can also be done multiple times to track changes over time.
Disadvantages: But, they might not be as detailed or accurate as invasive techniques.
In short, choosing between these methods depends on the situation. Doctors have to weigh how much they need precise information against keeping patients safe.
