- You have received a $500,000 grant from the National Science Foundation to study male signalling in peacock spiders. After your university takes most of that money for overhead costs, you now have a small amount left over to spend on peacock spider research over the next 3 years. What is the first question that you would focus on that you think would increase our understanding of peacock spider male displays the most? State a relevant hypothesis and explain briefly how you would go about testing it.To study the control of sex hormones on behavior, researchers may remove an animal’s ovaries or testes and then inject the animal with an estrogen or androgen of interest to see what behavioral effects they have. What advantage does this technique have over another approach, which is simply to measure the concentrations of specific hormones in the blood of animal subjects from time to time?Write a essay in the form of an introduction to the research area of the topic 'Neuroscience of social behaviour'. write an overview of 4 research articles explaining the contribution of these articles to research in the topic area. the 4 research articles are: orebrain control of behaviorally-driven social orienting in zebrafish by Sarah J. Stednitz perceptual mechanisms of social affiliation in zebrafish by Ana Rita nunes1 Genetic variation in the social environment affects behavioral phenotypes of oxytocin receptor mutants in zebrafish by Diogo Ribeiro1 Biological Motion as an Innate Perceptual Mechanism Driving Social Affiliation by Johannes Larsch
- Innate behavior allows animals to respond instantly. The simplest innate behaviors are reflex actions. Discuss the difference between an animal reflex from an instinct. Cite specific examples to illustrate your concepts.The prefrontal cortex receives extensive input from the amygdala, and it uses information about emotion to make the final determination about whether to engage in a specific behavior. Bechara and his colleagues conducted a study on decision-making that compared healthy individuals to patients with damage to the prefrontal cortex. Which of the following statements about this research is FALSE? A) Over time, patients with prefrontal injuries did not produce anticipatory reactions (sweating) before making a "risky" decision. B) At first, both groups of individuals chose the "risky" option more often. C) Both the healthy individuals and the patients eventually switched to the "safer" option once they figured out how the game worked. D) Over time, healthy individuals began to produce a strong anticipatory reaction (sweating) before making a "risky" decision.Long-term methamphetamine use leads to changes in the brain. Think about how methamphetamine changed where dopamine was found in the cell. What are some changes that you might expect based on this simulation?
- A study was done to see why crickets chirp and the reactions to stimulus that caused the audible sound to occur. Throughout the experiment they tested how a target (male) cricket interacts with different stimuli in the form of both male and female cricket. Their methods revolved around getting quantitive data on three separate behaviors that occurred in the target male: locomotion(any time the target did a continuous movement), contact(counted when the target touched a stimulus with any part of its body), and chirping(audible, chirp sound with leg or wing movement from the target). The target was rotated each test, so each data point came from a different cricket with the female stimulus, being the same each time, and their previous target becoming the male stimulus. They would place the two male crickets in the target bin and let them acclimate for two minutes before they began collecting data from the target for three minutes. Then the female stimulus was placed in the bin and left…An experiment with squirrels revealed that they make alarm sounds when a model of an owl is placed near them. When a red cube, about the same size as an owl is placed there, there seems to be no alarm. Which of the following best explains this reaction? The owl model is the ultimate cause of alarm vocalization behavior. The owl model, but not the red cube, triggers the fixed action pattern of alarm vocalizations. The squirrel is trying to attract the owl into its territory. The squirrels cannot see red objects, and so do not make alarm sounds. 0000Many neurotoxins have been used extensively in physiological studies of neurons. When comparing tetrodotoxin found in puffer fish and batrachotoxins from poison dart-frogs, the former had no effect on a neurons resting potential but completely stopped its action potential, whereas the later toxin immediately initiates depolarization of a neuron but prevents repolarization. Can your group hypothesize how these toxins affect the nerve transmission differently?
- What do these results suggest about the role of PKA in insects that are always gregarious? Insects that are always gregarious show an aberrant PKA activation cycle. PKA plays a role in modifying behavior patterns, but not in establishing the patterns. Gregarious insects do not express the PKA protein. PKA affects behavior only in solitary insects.Conventional signals are not costly because they often entail slight visible variations in only a small portion of the body, but they can be rendered honest through social reinforcement. Which example best demonstrates this case? A. Birds with large throat patches with poor fighting ability are attacked more often by dominant birds. B. Aggressive wasps with facial patterns indicating their fighting ability are less likely to be attacked. C. A dominant lion is able to evict younger chalengers from the pride. D. Female chimps will not mate with a male defeated in combat.Write a Worm neuronal function assay paragraph about a worm neuronal function and find an experiment that could test why the worm may have this worm neuronal function. Such as a worm spiraling. One robust assay of worm behavior is…. “Finish the sentence” and find an experiment that could determine why the worm behavior is this way.
