In return, Hopper apologized to Eleven and told her that it was his fault and that he was sorry for everything, as he thought he would have lost Eleven just like he'd lost his daughter. At the lab, Eleven and Hopper came across many dead bodies and ultimately found Dr. Owens, wounded but still . alive.
We begin with a brief review of the major structural and functional neuroimaging. research methods that are commonly in use, including computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), functional. magnetic resonance imaging (fMRI), and diffusion-weighted magnetic resonance.
Similarly our heart and our brain have wave patterns. The wave pattern of the heart is measured by ECG (electro cardiograph). The brain waves are measured by EEG (electro encephalograph). Using the brain wave studies, scientists have discovered that our brain waves are of four types. The brain waves also have peaks that are similar to the peaks we see in water waves.
