Exam 3: A:The Biological Bases of Behaviour

Zoe has a small brain tumour that is pressing on areas in her right frontal lobe. Which of the following would you expect to be the most difficult for Zoe as a result of this tumour?

Which gland secretes hormones associated with the development of secondary sex characteristics?

Which of the following would the use of a drug that functions as a dopamine agonist probably lead to?

Ricardo just came back from seeing a neurologist. Ricardo tells you that he will be having a test in which images of his brain will be recorded after radioactive chemicals have been injected into his bloodstream. What test will his neurologist be using?

Which of the following is a hindbrain structure involved with sleep and arousal?

According to the Hebbian Learning Rule, if an axon of Cell A is near enough to repeatedly stimulate Cell B (causing it to fire often) then what will happen to Cell B?

Which of the following procedures is done in order to study the functional specialization of the two sides of the brain?

What is the so-called "master gland" of the endocrine system?

In which of the following conditions do abnormalities at norepinephrine and serotonin synapses appear to play a role?

Which part of the nervous system mobilizes the body when one needs to exert tremendous energy, such as when fleeing from an attacker?

Which of the following hormones is associated with bonding and trust?

Dr. Ferracane has just discovered a new drug named GL8 that produces side effects such as paralysis and memory loss. Based on this information, how might this drug be acting on the nervous system?

If you destroy one area of the brain, an animal will lose all interest in food and may well starve to death. Which area is it?

Research by Olds and Milner identified a "pleasure centre" in rat brains and researchers have determined that rats will press a lever thousands of times in order to have a tiny electrode stimulate this area of the brain. What brain area is it?

Which cells in the nervous system do the work of receiving, integrating, and transmitting information?

Imagine the following scenario: Administrators at the local high school have been impressed by recent media reports of cerebral hemispheric specialization, and are considering curricular reform to achieve a better balance between "left-brained" and "right-brained" activities. You have been hired to advise them on this issue. What would your recommendation be, and why?

If a brain has several synapses that are not particularly active, and those synapses are eliminated, what does this reflect?

Which of the following statements most accurately reflects the roles of heredity and environment in shaping our behaviour?

You are planning to conduct a study using children and adolescents of various ages, in order to examine their performance in tasks involving perceptual asymmetries. In these tasks, each hemisphere receives different pieces of information. What issue might you need to consider in terms of experimental control before you conduct your study?

Which part of the nervous system controls digestion and the flow of blood?
