Neuroimaging techniques help us learn more about how our brains work by showing us what’s happening inside. Here are some important methods used in this field:

1. fMRI (Functional Magnetic Resonance Imaging):

   • This technique measures brain activity by looking at how blood flows.
   • It can pinpoint which areas of the brain are active with an accuracy of about 1-3 millimeters.

2. PET (Positron Emission Tomography):

   • This method checks how the brain uses energy by following special radioactive markers.
   • It can show changes in brain activity every 30 seconds, which is great for watching how the brain changes quickly.

3. EEG (Electroencephalography):

   • This technique tracks electrical signals from the brain using small sensors placed on the scalp.
   • It provides very fast results, measuring changes in just milliseconds. This is really important for studying how quickly the brain reacts.

In research about how we think and learn, neuroimaging has shown that around 80% of complex thinking tasks use many different networks in the brain. This helps us understand how various parts of our brain work together to manage memory, focus, and solving problems.
