Question 1

Brain mapping is done by __________.

Accepted Answer

Brain mapping is often done by stimulating the brain to observe the effects on behavior and function, helping to identify the roles of different brain areas.

Question 2

Doctors believe that Sarka has a tumor in her brain, because she is having trouble speaking and remembering. Based on the doctors' prediction, which of the following techniques will they most likely use to make a diagnosis?

Accepted Answer

Computed tomography (CT) is commonly used to detect brain tumors as it provides detailed images of the brain's structure, helping doctors identify abnormalities such as tumors.

Question 3

Researchers want to determine what part of the brain is most involved when a person is reading. Which of the following techniques are they most likely to use to study this question?

Accepted Answer

PET scans are often used to observe metabolic processes in the brain, making them suitable for studying brain activity during tasks like reading.

Question 4

Damage to the __________ will most likely result in death or the need to be placed on life-sustaining machines.

Accepted Answer

The medulla, part of the brainstem, controls vital functions such as breathing, heart rate, and blood pressure. Damage to it can be life-threatening, often necessitating life support or resulting in death.

Question 5

An auto accident has rendered Chris's nervous system unable to send messages for him to balance his body when standing up. What part of Chris's brain has most likely been damaged?

Accepted Answer

The cerebellum is primarily responsible for coordinating voluntary movements, including balance, coordination, and posture. Damage to this area can impair the ability to balance the body when standing up.

Question 6

Joel has been in an accident, and doctors have declared him to be in a coma because he is unable to respond to his surroundings. Unfortunately, the doctors cannot tell that he is actually aware of everything that is happening to him. Joel most likely has damaged his __________.

Accepted Answer

The answer of Joel has been in an accident, and...

Question 7

Kai is a soccer player. The motor impulses he needs to kick the ball originate in which lobe of the cerebral cortex?

Accepted Answer

The motor impulses required for physical movements such as kicking a ball originate in the frontal lobe of the cerebral cortex, specifically in the primary motor cortex. This area is responsible for planning, controlling, and executing voluntary movements.

Question 8

Split-brain surgery is often done to treat __________.

Accepted Answer

Split-brain surgery, also known as corpus callosotomy, is primarily performed to treat severe epileptic seizures that cannot be controlled with medication. It involves severing the corpus callosum, which connects the two hemispheres of the brain, to prevent the spread of seizure activity from one hemisphere to the other.

Question 9

Learning something new is represented by neural connections getting __________ in the brain.

Accepted Answer

Learning something new is represented by neural connections getting stronger in the brain, as this process involves the strengthening of synapses through mechanisms such as long-term potentiation.

Question 10

Which of the following is necessary for new cells in the brain to survive?

Accepted Answer

For new cells in the brain to survive, it is crucial that they are able to build connections with other neurons. This connectivity allows them to integrate into the existing neural networks and contribute to brain function.

Question 11

Gazzaniga and Sperry conducted research on epileptics who needed a specific surgery to hopefully help reduce the number of seizures they were having. This surgical procedure is called the __________.

Accepted Answer

Gazzaniga and Sperry conducted research on patients who had undergone a split-brain procedure, a surgery that involves severing the corpus callosum to reduce the severity of epileptic seizures. This procedure effectively splits the brain into two halves, which significantly impacts how the brain processes information.

Question 12

In the study conducted by Gazzaniga and Sperry, when patients were asked to report on information presented only to the right hemisphere, what happened?

Accepted Answer

The answer of In the study conducted by Gazzaniga and...

Question 13

What were the conclusions of the Gazzaniga and Sperry study?

Accepted Answer

The Gazzaniga and Sperry study concluded that while the brain can operate as a whole, the two hemispheres can function independently, each with its own specialized functions.

Question 14

In the Gazzaniga and Sperry study, what was the independent variable?

Accepted Answer

The answer of In the Gazzaniga and Sperry study, what...

Question 15

Compare and contrast the reductionist and holistic models of studying human behavior.

Accepted Answer

The answer of Compare and contrast the reductionist and holistic...

Question 16

Critique the biopsychosocial model for explaining behavior. Why might it be helpful and more accurate than other models, or why might it overcomplicate the evaluation of behavior? In your critique, include a definition of the model and provide examples of each of its elements.

Accepted Answer

The answer of Critique the biopsychosocial model for explaining behavior....

Question 17

Analyze the four main parts of the human neuron by explaining how they are related in structure and function. Clearly identify the role that each plays in the transmission of neural communication.

Accepted Answer

The answer of Analyze the four main parts of the...

Question 18

Identify the primary neurotransmitters discussed in your text. Distinguish between them based on their proposed functions. Propose one potential impact if a person has particularly low levels of each neurotransmitter.

Accepted Answer

The answer of Identify the primary neurotransmitters discussed in your...

Question 19

Compare and contrast the roles of the various divisions of the nervous system.

Accepted Answer

The answer of Compare and contrast the roles of the...

Question 20

Distinguish between the organizational and activational functions of the endocrine system.
