The Brain-Body Connection
What is the relationship between the brain and the body? The brain’s significance is evident in the concept of brain death. While organs like the heart, lungs, or liver can be transplanted, brain death signifies the end of a person. Brain activity, measured by an electroencephalogram (EEG), indicates the level of cellular activity in the brain, specifically the neurons and their synapses.
Brain Regions and Functions
