Unformatted text preview: Dr. Pozos just listed 7 one-word facts on how water is essential to life. Approximately how long can you potentially remember all 7 facts without looking or studying them again? 2-3 years after he lists them 2-3 hours after he lists them 2-3 minutes after he lists them 2-3 days after he lists them 2-3 months after he lists them The main part of the brain involved in making short-term memories is the frontal cortex basal forebrain hypothalamus hippocampus temporal cortex Neurotransmitters are made from RNA or proteins part of synapses caffeine and alcohol chemical messages activated neurons What kind of information is stored in your long-term memory? autobiographical information phone numbers new information social interactions places youve searched for a missing object What processes contribute to long-term potentiation? signaling through neurotransmitters communication between the presynaptic and the postsynaptic neurons activation of the presynaptic and the postsynaptic neurons all of these are correct none of these are correct What is not a potential way to lose your short-term memory? a car accident damages your basal forebrain structures Alzheimers disease blocks neuronal communication in your basal forebrain drinking a lot of caffeine boosts acetylcholine production in your basal forebrain a stroke causes neuronal cell death in your hippocampus drinking alcohol disrupts activity in the hippocampus Dr. Pozos partied like a rock star the night before, but now cant remember that he danced on the table with a lampshade on his head. How did the alcohol affect his ability to remember? alcohol blocks long-term potentiation alcohol affects the brains ability to transfer information from short to long-term memory alcohol disrupts activity in the hippocampus all of these are correct none of these are correct Which beverage would affect memory recall tasks? a 8.3 oz. Red Bull a 12 oz. can of Pepsi or Coca Cola a 16 oz. Monster Energy drink a 1 oz. Starbucks Espresso shot a 8 oz. cup of green tea You are studying for finals and just pulled an all-nighter. You have one more exam to take in 2 days. Knowing what you learned about how memories are formed, what is your best strategy for studying? rely on the fact that you have a photographic memory order a Venti latte from Starbucks to boost your acetylcholine levels, then study reapeat the information to yourself over and over study over the next 2 days, then get a good nights sleep before the exam pull another all-nighter to study for the exam How does sleep help improve our memories? the number of synapses in our brains increases during sleep the acetylcholine levels in our brains increases during sleep your mind replays the events of the day, reinforcing new memories long-term potentiation occurs during sleep levels of neurotransmitters increase during sleep How does alcohol cause blackouts for social drinkers?...
