Accepted Answer

PET stands for positron emission tomography and is a brain imaging technique that detects the uptake of certain molecules in the brain, such as glucose or oxygen.

Answer: B
 EEG stands for electroencephalography and is a brain imaging technique that detects changes in the electrical activity of the brain over time, often measured using electrodes placed on the scalp. It is also able to detect changes in blood flow in the brain.

Answer: A
 fMRI stands for functional magnetic resonance imaging and is a brain imaging technique that measures changes in blood flow in the brain to infer neural activity. It does not record the brain's electrical activity from the scalp.

Question 3

Although split brain patients show deficits in processing in laboratory experiments,they appear to have few problems in the real world.

Accepted Answer

Split brain patients have been shown to have some deficits in laboratory experiments, such as difficulties with visual-spatial tasks and processing certain types of information. However, in the real world, these deficits seem to have little impact on their daily functioning. In fact, many split brain patients are able to lead normal lives and perform complex tasks without any significant issues.

Question 4

Dr.Draco wants to study attentional processes in a healthy,intact,normal human brain.What is the best technique for her to use to accomplish this goal?

Accepted Answer

Neuroimaging techniques, such as functional magnetic resonance imaging (fMRI), allow researchers to observe brain activity in healthy individuals without manipulating or damaging the brain. This would be the best technique for Dr. Draco to use to study attentional processes in a healthy, intact, normal human brain.

Question 5

Lesioning is to ___ as TMS is to ___.

Accepted Answer

Lesioning is typically performed on animals to study the effects of brain damage, while TMS can be used on both humans and animals but is more commonly used on human subjects in neuroscientific research.

Accepted Answer

The answer of The number of eyespots on the peacock's...

Question 7

Canadian and American statistics suggest that males are more likely to kill children who are genetically related to them than those who are NOT.

Accepted Answer

Statistics and research in both Canada and the United States indicate that males are more likely to harm or kill children who are not genetically related to them (i.e., stepchildren) than their own biological children, a phenomenon often related to the "Cinderella Effect."

Question 8

Dr.Kensington is a neuropsychologist conducting a case study with a patient who lost the ability to speak after a stroke.What will he be able to learn by studying this patient's brain?

Accepted Answer

By studying the patient's brain, Dr.Kensington will be able to learn which specific brain areas are involved in the speech function that the patient lost. This information can help in developing targeted interventions for the patient and understanding more about the brain's language processes. The other options (A, B, and D) are not directly related to studying the patient's brain, but rather involve different aspects such as determining the cause of the stroke, prevention, and life expectancy.

Question 9

Women are less intelligent than men because their brains are smaller.

Accepted Answer

This statement is false. Brain size is not necessarily an indicator of intelligence, as there are many other factors that contribute to intelligence such as neural connections and overall brain activity. Additionally, studies have shown that there is no significant difference in overall intelligence between men and women.

Question 10

Broca's area is critical for speech production.

Accepted Answer

Broca's area, located in the left frontal lobe of the brain, is responsible for speech production, including motor planning and execution of speech movements. Damage to Broca's area can result in a type of aphasia called Broca's aphasia, which is characterized by difficulty in producing language and forming complete sentences.

Question 11

Left-handed individuals are more likely to have their language areas located on the right side of their brains than are right-handed individuals.

Accepted Answer

Studies have shown that left-handed individuals are more likely to have their language areas located on the right side of their brains, indicating a higher degree of brain plasticity and flexibility. However, this does not mean that all left-handed individuals have right-lateralized language areas, and there is still variability within both left- and right-handed individuals.

Question 12

Dr.Baker is studying the activity in the brain of a participant when they are in REM sleep and comparing that to the activity when they're fully alert.Given this goal,what is the best technique for Dr.Baker to use?

Accepted Answer

Electroencephalogram (EEG) is the most appropriate technique for studying brain activity during sleep and comparing it to alertness as it measures the electrical activity in the brain. EEG is non-invasive and has a high temporal resolution, which allows for measuring millisecond-level changes in brain activity. In contrast, diffusion tensor imaging and magnetic resonance imaging mainly capture structural images of the brain, while positron emission tomography is more suitable for studying metabolic and neurotransmitter changes in the brain, but it involves exposing the participant to radiation.

Question 13

Dr.Baku is investigating the function of the amygdala,and comparing activation when participants view emotionally charged photos versus serene scenery photos.Given the choices below,what is the best technique for Dr.Baku to use for this project?

Accepted Answer

Positron emission tomography (PET) is the best choice for this project because it can measure brain activity by detecting changes in blood flow and can provide a 3D image of brain function. PET scans can show which areas of the brain are activated when participants view emotionally charged photos and serene scenery photos, enabling Dr.Baku to investigate the function of the amygdala. Other neuroimaging techniques like MRI, diffusion tensor imaging, and event-related potential are not as effective as PET for measuring brain activity while participants are viewing emotional stimuli.

Question 14

Jack's uncle had Alzheimer's disease and when he died,he left his brain to medical science Which of the following techniques would be used to study Jack's uncle's brain?

Accepted Answer

Autopsy is the only technique mentioned that is able to directly examine the brain tissue itself, which would be necessary for studying the effects of Alzheimer's disease on the brain. The other techniques listed (neuroimaging, transcranial magnetic stimulation, and evoked related potentials) all indirectly measure activity in the brain, but do not provide information about the physical structure or composition of the brain tissue.

Question 15

Dr.Alfine wants to know about the activity of the brain when someone is meditating and compare that to the activity when they're hypnotized.What would be the best technique for Dr.Alfine to use for this project?

Accepted Answer

The best technique for Dr.Alfine to use for this project would be electroencephalogram (EEG), as it is a non-invasive method to measure brain activity by recording electrical signals from the brain using electrodes placed on the scalp. This technique can be used to detect brain waves during meditation and hypnosis and compare the activity between the two states. Diffusion tensor imaging (DTI) and magnetic resonance imaging (MRI) mainly focus on imaging the structure of the brain and may not provide enough detailed information on the activity of the brain during these states. Positron emission tomography (PET) is useful in measuring blood flow and metabolism in the brain, but EEG may provide more specific and sensitive data in this case.

Question 16

What technological advance allows scientists to study brain activity in healthy,awake humans?

Accepted Answer

Neuroimaging techniques such as fMRI, PET, and EEG allow scientists to study brain activity in healthy, awake humans. Lesioning involves damaging or destroying a part of the brain to observe its effects, but this is typically done in animal studies or in rare cases with patients who have already suffered a brain injury. Autopsy involves examining the brain after death, which does not allow for the study of brain activity in a living human. Psychoanalysis is a form of therapy and does not involve the direct study of brain activity.

Question 17

Dr.Fargas is interested in investigating the memory processes in a healthy,intact,normal human brain.Given what you know about techniques for studying the brain,what technique would you recommend?

Accepted Answer

Neuroimaging techniques such as fMRI, PET, and EEG can provide insight into the memory processes in a healthy human brain by detecting the areas of the brain that are activated during memory tasks. This non-invasive technique allows for the study of brain function without causing any harm or altering the brain in any way.

Question 18

Which of the following ways to study the brain is NOT a neuroimaging technique?

Accepted Answer

Lesioning is not a neuroimaging technique. It involves purposefully damaging or removing specific areas of the brain to observe resulting changes in behavior or function. The other three options (functional magnetic resonance imaging, diffusion tensor imaging, and positron emission tomography) are neuroimaging techniques that involve using various technologies to visualize brain activity or structure.

Question 19

Which of the following brain study techniques is correctly matched with a disadvantage?

Accepted Answer
