Exam 3: The Biological and Evolutionary Bases of Behavior

If we can apply Mark Rosenzweig's research on rats raised in impoverished or enriched environments to humans, then we would encourage humans to live in a(n)

A doctor on television is discussing the curious case of G.R., a patient who has suffered damage to his brain. G.R. believes that it is still 1970 and that the last Olympic games were held in Mexico in 1968, even though it is now the 21st century. Before the doctor divulges the part of the brain that is damaged in this individual, you predict that it is the

During the absolute refractory period,

Imagine that you have gone to the garden to pick a rose. Unfortunately, when reaching for a flower, your thumb encounters a thorn and you jerk your hand away. What is the order in which information is communicated, from the time of the prick through withdrawal of your hand and realization of pain?

While surfing the Web, you stop at an anthropology website. There, you learn that natural selection favored two major adaptations in the evolution of the human species:

Heritability is measured on a scale of

The majority of the cerebral cortex is involved in

A mystery writer can't decide how the victim will meet his end. One possibility is to have him suffer botulism poisoning, but curare, a poison used by Amazon Indians, is also a possibility. In either case, the victim's death will involve the neurotransmitter

You arrive at class late, and walk in during the part of the lecture describing how action potentials work. The professor says, "the channels that allow sodium to flow into the neuron have just closed and the channels that allow potassium to flow out have opened." You can conclude that the cell is

Sex chromosomes

The cerebrum is divided into two almost symmetrical halves, called the ________, which are connected by a mass of fibers called the ________.

Taking a shortcut through the park late one night, you catch a glimpse of movement in the shadows. Automatically, your ________ mobilizes your body into action and your ________ tells the muscles in your legs to run.

Imagine that you have been asked to give a short talk on the functioning of the auditory cortex. Make sure NOT to tell your audience that

When the neuron is inactive, we say it is in a resting state. When it is in such a state,

Diagram a neuron, label its parts, and describe how it works. In your description, be sure to provide a brief explanation of the resting potential and the action potential. Then, explain how information flows from neuron to neuron. How does information transmission in the nervous system differ from the information transmission that takes place in the endocrine system?

The image of a key fitting into a keyhole is most useful in understanding how

The myelin sheath, which is found around some types of axons,

A classmate is working on her presentation on the endocrine system for class. You overhear her as she says, "This gland is often called the 'master gland' because it has an effect on the secretions of all the other endocrine glands." It sounds as though she is talking about the

The ________ shows where different types of activity are occurring in the brain and involves the use of a safe radioactive substance that is given to participants.

Charles Darwin noted that among the finches on the various Galápagos Islands, the factor that differentiated those that survived from those that didn't was
