A) electrode.
B) inductor.
C) neuralizer.
D) telemetry instrument.

Accepted Answer

An electrode is a device used to electrically stimulate or destroy nerve tissue or to record its activity. The other options, inductor, neuralizer, and telemetry instrument, do not accurately describe this function.

Question 3

In order to detect the electrical activity of a single neuron, a scientist would most likely use
A) ESB.
B) a microelectrode.
C) PET.
D) fMRI.

Accepted Answer

A microelectrode is a thin, hair-like electrode that can be inserted into a single neuron to detect its electrical activity. ESB (electrical stimulation of the brain), PET (positron emission tomography), and fMRI (functional magnetic resonance imaging) are imaging techniques that do not directly measure the electrical activity of a single neuron.

Question 4

The destruction of brain tissue occurs with both deep lesioning and with surgical
A) fMRI.
B) PET.
C) electroencephalography.
D) ablation.

Accepted Answer

Ablation refers to the intentional destruction of brain tissue and is a surgical technique used in neuroscience research. Lesioning may refer to intentionally damaging or removing brain tissue through a variety of methods, which can include ablation but also other techniques such as radiofrequency or chemical lesioning. fMRI, PET, and electroencephalography are all imaging techniques used to measure brain activity and do not involve the intentional destruction of brain tissue.

Question 5

PET scans and EEGs are considered __________ imaging techniques.
A) structural
B) functional
C) hemispheric
D) subcortical

Accepted Answer

PET scans and EEGs are considered functional imaging techniques because they measure brain activity and function, rather than just the physical structures of the brain.

Question 6

The use of an electrode to destroy small areas of the brain beneath the surface is called
A) PET.
B) neural induction.
C) deep lesioning.
D) electroencephalography.

Accepted Answer

The use of an electrode to destroy small areas of the brain beneath the surface is called deep lesioning. PET (A) is a brain imaging technique that uses a radioactive tracer to produce a 3D image of brain activity. Neural induction (B) is the process by which an embryonic cell develops into a neural precursor cell. Electroencephalography (D) is a non-invasive method for recording electrical activity in the brain using electrodes placed on the scalp.

Question 7

Biopsychologists are able to pinpoint areas in the brain responsible for thoughts, feelings, and actions using all of the following EXCEPT for the
A) EEG.
B) fMRI.
C) PET scan.
D) CT scan.

Accepted Answer

CT scans, while useful for revealing brain structures, do not directly show brain activity or how different areas of the brain engage in thoughts, feelings, and actions. EEG, fMRI, and PET scans are all used to study brain function and can help identify areas responsible for specific cognitive and emotional processes.

Question 8

Three of these techniques allow scientists to observe the activity of parts of the brain without doing any damage at all.Which technique would cause some degree of damage to the living brain?
A) EEG
B) fMRI
C) PET scan
D) ablation

Accepted Answer

Ablation involves the intentional removal or destruction of a part of the brain, and therefore would cause damage to the living brain. EEG, fMRI, and PET scans are all non-invasive techniques that do not cause any physical damage to the brain.

Question 9

Scientists implanted an electrode into a specific area of a rat's brain.When the electrode was activated, which in turn activated the target area, the rat aggressively attacked a cat within the same cage.The technique being utilized by the scientists is known as
A) ESB.
B) ablation.
C) deep lesioning.
D) PET.

Accepted Answer

ESB (Electrical Stimulation of the Brain) involves the implantation of an electrode into specific areas of the brain in order to study the function of those areas. In this case, activating the electrode led to aggressive behavior in the rat, indicating that the targeted area is involved in aggression. Ablation involves removing or destroying specific areas of the brain, while deep lesioning involves damaging specific areas of the brain. PET (Positron Emission Tomography) is a brain imaging technique that involves injecting a tracer substance into the bloodstream and tracking its movement through the brain. None of these techniques involve implanting electrodes into the brain to directly activate specific areas.

Question 10

An extremely thin glass tube filled with a salty fluid with its tip being small enough to detect the electrical activity of a single neuron would be referred to as a(n)
A) pixel.
B) microelectrode.
C) PET scan.
D) fMRI.

Accepted Answer

A microelectrode is a very small electrode used to record electrical activity from single neurons or other units in the central or peripheral nervous system. The tip of the electrode is small enough to penetrate a single cell and the solution inside the electrode allows for the detection of changes in electrical activity.

Question 11

Scientists destroyed a tiny area of a cat's limbic system by inserting a tiny electrode into this target area and then passing an electric current through the electrode.They then observed the cat for any changes in its behavior, which wouldprovide clues about the function of this affected area.The procedure that was used to destroy the tiny area in the cat's brain is known as
A) ESB.
B) neural induction.
C) deep lesioning.
D) FMRI.

Accepted Answer

Deep lesioning involves destroying a tiny area of the brain by passing an electric current through an electrode, as described in the scenario. ESB (Electrical Stimulation of the Brain) is a different procedure that involves stimulating rather than destroying brain tissue. Neural induction is a process that occurs naturally during embryonic development and is not related to the scenario. FMRI (Functional Magnetic Resonance Imaging) is a different technique that uses magnetic fields to detect changes in blood flow in the brain and is not related to the scenario.

Question 12

A doctor activates the surface of a patient's brain by touching it with a small electrified wire and the patient tells the doctor what effect the stimulation had.Regarding this procedure, which of the following statements is TRUE?
A) This procedure is impossible because patients cannot be awake during brain procedures.
B) The doctor is performing an ablation.
C) The doctor is using an electrode to "turn on" brain structures.
D) The doctor is using an EEG to "turn on" brain structures.

Accepted Answer

The doctor is using an electrode to "turn on" brain structures. This procedure is known as direct brain stimulation and can be used to map the functions of different areas of the brain. Patients can be awake during brain procedures if anesthesia is used to numb the scalp and skull, but not the brain itself. The doctor is not performing an ablation, which is the removal of tissue, and is not using an EEG, which is a non-invasive technique that records brain activity from the scalp.

Question 13

Which of the following techniques provides a fascinating glimpse into the true origins of behavior by allowing scientists to view the action potentials of a single neuron?
A) ablation
B) deep lesioning
C) PET scans
D) microelectrode recording

Accepted Answer

Microelectrode recording is the technique that allows scientists to view the action potentials of a single neuron, providing insight into the origins of behavior. Ablation and deep lesioning involve damaging parts of the brain to study the resulting effects, while PET scans use radiation to measure brain activity.

Question 14

The procedure that detects, amplifies, and records electrical activity in the brain is known as
A) electrical stimulation of the brain (ESB).
B) functional MRI (fMRI).
C) electroencephalography (EEG).
D) positron emission tomography (PET).

Accepted Answer

The procedure that detects, amplifies, and records electrical activity in the brain is known as electroencephalography (EEG). Electrical stimulation of the brain (ESB) refers to the use of electrical current to stimulate specific regions of the brain, while functional MRI (fMRI) and positron emission tomography (PET) are imaging techniques that measure changes in blood flow or metabolism in the brain.

Question 15

The use of an electrode to stimulate small areas of the brain beneath the surface is called
A) ESB.
B) deep lesioning.
C) fMRI.
D) electroencephalography.

B) Electrical stimulation of the brain (ESB)has been used to instantly call forth euphoria, aggression, or tears in a person.
C) Electrical stimulation of the brain (ESB)is done during brain surgery while the patient is awake, so they can describe the effect of the stimulation.
D) Electrical stimulation of the brain (ESB)cannot be used to bring forth behaviors, such as eating, sleeping, or speech in a person.

Accepted Answer

Electrical stimulation of the brain (ESB) has been used to bring forth behaviors such as eating, sleeping, or speech, making statement D false.

Question 17

Dr.Anton removed a tumor from the back surface area of a patient's brain.After removal of this brain tissue, the patient experienced extreme visual problems.This type of surgical removal of brain tissue is called
A) deep lesioning.
B) ablation.
C) ESB.
D) fMRI.

Accepted Answer

Ablation is the surgical removal of brain tissue, often used to treat tumors or other abnormalities. However, it can result in significant changes in brain function, including sensory and motor deficits, as well as cognitive or emotional changes. In this case, the patient experienced visual problems after the removal of tissue from the back surface area of the brain, which is responsible for visual processing.

Question 18

In biopsychology, the surgical removal of tissue from the surface of the brain is called
A) ablation.
B) neuroplasticity.
C) the clinical method.
D) neural induction.

Accepted Answer

Ablation refers to the removal of tissue from the surface of the brain, typically done in research to investigate the function of specific brain areas. Neuroplasticity refers to the brain's ability to change and adapt, while the clinical method is a general approach to studying behavior and disorders, and neural induction refers to the process by which cells differentiate into neurons.

Question 19

An electroencephalograph (EEG)records
A) the number of neurons in the brain.
B) electrical impulses from the brain.
C) chemical activity in the cranial nerves.
D) the amount of glucose being utilized by the brain.

Accepted Answer

An electroencephalograph (EEG) is a device used to record electrical impulses from the brain. These impulses are generated by the activity of neurons and can be used to diagnose various neurological disorders. EEG does not record the number of neurons in the brain, chemical activity in the cranial nerves, or the amount of glucose being utilized by the brain.

Question 20

Pierre Flourens surgically removed portions of a rabbit's cerebellum with the rabbit subsequently showing extreme problems with motor coordination.This surgical removal of the surface portions of the cerebellum is an example of
A) ablation.
B) deep lesioning.
C) ESB.
D) fMRI.

Accepted Answer

Ablation refers to the surgical removal or destruction of a particular brain region. In this case, Flourens surgically removed portions of the rabbit's cerebellum, leading to motor coordination problems. Deep lesioning refers to the insertion of an electrode deep into the brain to destroy tissue, which was not the case in this experiment. ESB (electrical stimulation of the brain) and fMRI (functional magnetic resonance imaging) were not used in this experiment.
