lTechnology paved the way for understanding how bring works. 
 lEnabled researchers to understand and see inside the brain. 
 lBrain scanners developed - Brain Imaging Technology
 
 ¡Magnetic Resonance Imaging (MRI) 
 ¡Positron Emission Tomography (PET) – Radioactive glucose
 used to determine
 activity in different parts of the brain 
 ¡Electroencephalography (EEG) – Electrodes give us
 readings about electrical output
 of the brain
