How is the hypothalamus involved in sleep? A. Cell clusters in the hypothalamus stimulate the production of relatively slow alpha waves, signaling the transition from deep relaxation to sleep. B. The hypothalamus triggers the pituitary gland in the endocrine system to produce the hormone thyroxin, which leads you to sleep. C. During sleep, the hypothalamus stimulates the production of free radicals, molecules that are toxic to neurons, which weakens unused connections D. In response to decreasing light, the hypothalamus' suprachiasmatic nucleus causes the pineal gland to increase the production of melatonin, leading you to sleep E. The action of the hypothalamus suppresses immune cell production that fights off viral infections and cancer
D. In response to decreasing light, the hypothalamus' suprachiasmatic nucleus causes the pineal gland to increase the production of melatonin, leading you to sleep

Every day as she walks to school, Mamie passes a mural painted on the side of a building. However, when asked, she says she does not remember ever seeing it. Which of the following is the best explanation for this occurrence? a. Such implicit memory is stored in the cerebellum, thus Mamie must have experienced damage to that brain region. b. Mamie has not paid attention to the incoming information so it was not encoded into long-term memory. c. Because of the time span between being exposed to the mural, the spacing effect has interrupted memory formation. d. The memory of the mural has decayed over time. e. Mamie is experiencing retroactive interference, leading to her forgetting past information.
b. Mamie has not paid attention to the incoming information so it was not encoded
