To understand how our brains change and adapt, we need to look at some important ways to measure brain activity. Here are the main methods:

1. Electrophysiological Techniques:

   • EEG (Electroencephalography): This tool checks the electrical signals in the brain. It shows how pathways in the brain adjust when we learn new things.
   • MEG (Magnetoencephalography): This method finds the magnetic fields that come from brain activity. It's great for spotting changes in brain circuits.

2. Imaging Techniques:

   • fMRI (Functional Magnetic Resonance Imaging): This technique shows how blood flows in the brain when we learn. It helps us see which parts of the brain are active during learning.

3. Neurotransmitter Tests:

   • By measuring chemicals in the brain, like glutamate, we can learn about changes at the connections between brain cells. This is important for understanding learning and memory.

These measurement techniques help us see how the brain changes in response to new experiences.
