Exam 3: A:The Biological Bases of Behaviour

What do synaptic vesicles do?

Omar suffered a stroke, and even though he has recovered many functions, he finds he is still relatively insensitive to pain signals from his right leg. In this case, which lobe is damaged?

Imagine that you and Charles Darwin are standing in a barn, looking at a newborn litter of kittens. There are differences in the kittens in terms of size, colouring, temperament and appetite. As you observe the kittens, you ask Mr. Darwin which of the kittens will be most "fit" in terms of natural selection. What would Mr. Darwin be most likely to say in response to your question?

Which of the following does NOT belong with the others?

Caitlin has taken a drug that has reduced the levels of GABA in her nervous system. What side effect is Caitlin likely to experience?

Donavon was adopted at birth by Mr. and Mrs. Erndt. Although neither of his biological parents had much musical ability, Donavon has become an excellent pianist, just like Mr. Erndt. What would this evidence suggest if this pattern held up across multiple adoption studies?

As far as we know, which humans have the same genotype?

Which of the following techniques is likely to be most useful for locating specific neurotransmitter activity in the brain?

What do we call the member of a gene pair that is more influential in terms of expressing a trait?

What is the key advantage to using fMRI rather than just an MRI?

Assume that developing a sixth toe is a recessive trait that is controlled by a single pair of genes. If a child has six toes, but both the child's biological parents have normal feet, what can you conclude?

The neurons in Noor's arm just sent a neural impulse. It will be 1-2 milliseconds before another neural impulse can be generated. What do we call this brief time increment, when another neural impulse cannot occur?

Which division of the nervous system is necessary if you need to stand up or scratch your nose?

What is the term for the minimum length of time between action potentials?

What occurs when gene frequencies in a population shift because some individuals leave the population (emigration) and others enter it (immigration)?

Sharif suffered a stroke recently, and now he finds he constantly hears a buzzing sound in his ear. Where is the damage located?

Peggy smells a very strong odour; Harry smells an odour that is barely detectable. Based on what is known about neural transmission, what should we predict about each of their action potentials?

Which of the following is a characteristic of both sodium and potassium ions?

By altering brain structures, an evil scientist has created superheroes who have specialized powers or abilities. One of these superheroes has a fantastic memory and is able to form new memories incredibly well. In this case, which brain structure was likely altered?

Johann took some medication for his flu symptoms. Later, Johann began to feel a little faint because the medication caused his heart to beat more slowly and his blood pressure to fall. What system was likely activated by the medication?
