Question 1

A study contrasting normal rats and ADX rats (which had their adrenal glands removed) observed that:

Accepted Answer

ADX rats, which lack adrenal glands, have difficulty remembering objects due to the absence of corticosterone, a hormone involved in memory processes.

Question 2

_____ is a technique that allows researchers to label different neurons by marking them with distinct colors using genetic manipulation.

Accepted Answer

Brainbow is a technique that allows researchers to label different neurons by marking them with distinct colors using genetic manipulation.

Question 3

Lashley made lesions on the cortices of rats in his search for the location of memory. He found that:

Accepted Answer

Lashley's experiments led him to conclude that memory is not localized to a specific area of the brain but is instead distributed across various regions of the cortex.

Question 4

In a study on infant language, researchers found that when newborn infants listened to a familiar language, there was a(n) _____ in oxygenated hemoglobin, and when they listened to an unfamiliar language, there was _____ in oxygenated hemoglobin.

Accepted Answer

When newborn infants listened to a familiar language, there was an increase in oxygenated hemoglobin, indicating brain activity and recognition. Conversely, when they listened to an unfamiliar language, there was a decrease, suggesting less engagement or recognition.

Question 5

The first field to study the relationship between brain function and behavior was:

Accepted Answer

Neuropsychology was the first field to specifically study the relationship between brain function and behavior, focusing on how brain injuries and abnormalities affect cognitive functions and behaviors.

Question 6

To ablate means to:

Accepted Answer

Ablation is the process of removing or destroying material from a surface.

Question 7

Broca's area is located in the:

Accepted Answer

Broca's area is located in the frontal lobe of the brain, typically in the left hemisphere, and is associated with speech production.

Question 8

Why are rats often used in research studies on behavior?

Accepted Answer

Rats have complex and varied behaviors, making them suitable for studying a wide range of behavioral phenomena.

Question 9

Modifying the brain and observing the effects on behavior is a valuable experimental tool because it allows:

Accepted Answer

Modifying the brain and observing the effects on behavior allows researchers to develop testable hypotheses, test these hypotheses experimentally, and develop animal models of human disorders, making all the options correct.

Question 10

_____ is the study of the biological bases of behavior.

Accepted Answer

Behavioral neuroscience is the field that studies the biological bases of behavior, focusing on how the brain and nervous system influence actions, thoughts, and emotions.

Question 11

The Corsi test measures:

Accepted Answer

The Corsi test is designed to assess spatial memory, which involves the ability to remember the locations and sequences of visual stimuli.

Question 12

For measuring spatial memory in rats, the platform is placed in one location for numerous trials to measure _____, whereas for measuring _____, the platform is placed in a new location on each trial.

Accepted Answer

Place learning involves the platform being in the same location to assess the rat's ability to remember that specific location. Matching-to-place learning involves changing the platform's location to assess the rat's ability to adapt and remember new locations.

Question 13

The mirror-drawing task measures:

Accepted Answer

The mirror-drawing task is used to assess motor memory, as it involves learning and remembering motor skills to trace a shape while looking at its reflection in a mirror.

Question 14

What does Brainbow allow researchers to do?

Accepted Answer

Brainbow is a technique that allows researchers to visualize individual neurons in the brain by labeling them with different fluorescent proteins, enabling them to see where neurons send their processes and how they connect with other neurons.

Question 15

A three-dimensional image of living tissue can be generated by:

Accepted Answer

Multiphoton imaging is a technique that allows for the visualization of living tissues in three dimensions by using multiple photons to excite fluorescent dyes within the tissue.

Question 16

The _____ memory task measures whether subjects have seen an item before and, if so, how recently.

Accepted Answer

The recency memory task assesses whether subjects can recognize an item as familiar and determine how recently they encountered it.

Question 17

What is functional near-infrared spectroscopy?

Accepted Answer

Functional near-infrared spectroscopy (fNIRS) is a noninvasive technique that uses light to measure brain activity by detecting changes in blood oxygenation and blood volume in the cortex.

Question 18

_____ stains show cell bodies, whereas _____ stains show cell bodies and processes (e.g., dendrites).

Accepted Answer

Nissl stains highlight cell bodies by staining RNA in the rough endoplasmic reticulum, while Golgi stains fill entire neurons, including cell bodies and processes like dendrites and axons.

Question 19

The electroencephalograph (EEG) was invented by:

Accepted Answer

Hans Berger was the inventor of the electroencephalograph (EEG), which is used to measure electrical activity in the brain.

Question 20

In rats, place learning is measured using:

Accepted Answer

Place learning in rats is commonly measured using the Morris water maze, which involves a hidden escape platform in a swimming pool.
