Extracted text: A group of psychologists wondered if inhaling pure oxygen could enhance a person's mental capacity. They tested forty-five students. These students breathed through a face mask for one minute. They were either given pure oxygen or normal air, but they did not know which. Those receiving pure oxygen could recall twice as many words as those receiving normal air (from Mihill, 1996). Using your knowledge of the nervous system, sensory system and endocrine system, suggests reasons for memory improvement as well as which structures may be involved. Be sure to prove your argument!*
