- The _____ is an area of the hypothalamus that initiates eating and controls several aspects of feeding behavior and metabolic processes. It controls chewing and swallowing, salivation, gastric juice secretion, and insulin production. It also arouses the cortex, causing increased locomotion and food-seeking behavior. A) lateral hypothalamus B) suprachiasmatic nucleus C) subfornical nucleusThe brain uses approximately what percent of the body's energy? 1% 5% 20% 50%The memory trend shown as humans increase in age is: recognition stays the same, while recall increases recognition decreases, while recall stays the same recognition stays the same, while recall decreases recognition and recall decrease
- What is mind map? How do we do it?A long time ago, there once was an anti-drug public service announcement campaign that showed fried eggs in a pan with the voiceover, "This is your brain on drugs." Let's find out why that ad campaign is true. 1) Pick a non-legal drug. 2) Research what it does to the brain in detail. 3) Are addicts of this drug's brains different from brains of non-addicts? 4) Why or why not? 5) What treatments are used for addicts of this drug? 6) What helps people recover from this drug's addiction besides medicines?. A classmate claims that when an organism is scared, the brain tries to prepare the body to run away. How does the evidence provided support this argument? (a) An increased heart rate means that the organism is paying more attention to their surroundings (b) The brain is telling the heart to beat faster, sending more oxygen to the muscles (c) The brain tries to calm the body down so that it doesn’t hyperventilate and faint (d) The brain is telling the eyes to see better, so the organism can find an escape route
- Let's say you are making a new recipe for the first time. You'll need to read the recipe, measure ingredients, mix your batter, and bake it. Describe four parts of the nervous system you will use and how you will use them while you are making the cake. (There is more than 4, but only need to four).The processing, which allows the same kinds of information to be processed in different brain structures, is called: Stream segregation Serial processing Distributed processing Parallel processing Notice it says "allows the same kind of information"Researchers investigating the effect of exercise on cognitive functions conducted a con- trolled experiment in which rats were randomly assigned to sedentary (Sed), low-intensity exercise (Low-Ex), or high-intensity exercise (High-Ex) groups. During this exercise regi- ment, rats were also trained to navigate a specialized water maze, and their escape la tency, the time it took them to escape the maze, was recorded. The results of this experi- ment are depicted in the figure below. escape latency (sec) 100 80 60- 40- 20 0- day 10 day 11 Escape latencies during the training phase Based on the data above, day 12 (b) Identify the control group in the experiment. sed -- low-ex -- high-ex (a) Identify the dependent and independent variables in the experiment. day 13 Respond to each part in 3 to 4 complete sentences. (c) Compare the effects of low-intensity and high-intensity exercise on the rats' cognitive func- tion during the training period.
