PSY 101 Lecture Notes - Lecture 3: Functional Magnetic Resonance Imaging, Positron Emission Tomography, Highlight (Band)
Document Summary
Highlight = look over notes when he puts them up/missed some. The way your brain works is through the interconnectedness of neurons. When you learn something, you"re creating, activating and/or strengthening those pathways between neurons. This is why practice makes you better at almost everything /// practice reinforces those neuronal links and makes future activation easier and more reliable. Everything you do has its origin somewhere in the brain. Research on the brain is difficult, because it"s very well protected by the body. The skull is the first, main barrier. The brain is also protected by the blood-brain barrier. This allows the diffusion of some compounds from the blood, but selectively. The brain is also quite complex, so there"s no clean one to one relationship with action. One method of measuring brain activation is seeing where the blood is flowing. The more blood in an area, the more activity.
