Question 1

Somatosensory cortex is to auditory cortex as the _______ lobe is to the _______ lobe.

Accepted Answer

The somatosensory cortex, responsible for processing sensory information from the body, is located in the parietal lobe, while the auditory cortex, responsible for processing sound, is located in the temporal lobe.

Question 2

Which of the following approximate correlation coefficients is a researcher most likely to obtain between IQ score and ratio of brain weight to body weight

Accepted Answer

The answer of Which of the following approximate correlation coefficients...

Question 3

Which of the following statements best describes the relationship between the amount of motor cortex devoted to the control of a particular movement and the degree of precision required by the movement

Accepted Answer

There is a positive correlation between the amount of motor cortex devoted to the control of a particular movement and the degree of precision required by the movement. This means that movements requiring more precision, such as those involving fine motor skills, will require a larger area of motor cortex to control them compared to movements that require less precision. This relationship has been supported by studies examining the organization of the motor cortex and the size of its representations for different body parts.

Question 4

Which of the following defines brain lateralization

Accepted Answer

Brain lateralization refers to the specialization of different tasks or abilities in each hemisphere of the brain. The left hemisphere is typically associated with language, math, and logical reasoning while the right hemisphere is associated with spatial awareness, creativity, and emotion. While both hemispheres work together for most daily activities, certain tasks may be dominated by one hemisphere.

Question 5

The outer bark-like layer of the brain is termed the _________.

Accepted Answer

The outer layer of the brain is called the cerebral cortex. It is responsible for complex functions such as sensation, perception, voluntary movement, and thought. The other options, brain stem, association area, and cerebellum, are all parts of the brain but they do not refer to the outer bark-like layer.

Question 6

The production of new neurons is called __________.

Accepted Answer

The production of new neurons is specifically referred to as neurogenesis. Therefore, the best choice is B. A, C, and D are incorrect as they do not accurately describe the process of producing new neurons.

Question 7

In the ________ areas of the cortex,sensory and motor information is combined and linked with stored knowledge.

Accepted Answer

Association areas of the cortex are responsible for combining sensory and motor information and linking it with stored knowledge. This allows for higher cognitive processes such as perception, memory, and language. Correlation, comparison, and relational areas of the cortex are not established or recognized categories.

Question 8

If Gina is standing facing toward you,which of the following sequences correctly orders the lobes of her cortex,from the region that is closest to you to the region that is farthest away from you

Accepted Answer

When someone is facing towards you, the frontal lobe is closest to you and the occipital lobe is farthest away from you. Therefore, the correct sequence is frontal → temporal and parietal → occipital. Choice C correctly orders the lobes in this sequence.

Question 9

The nervous system contains not only neurons,but also other cells called ___________.

Accepted Answer

Glia, also known as glial cells, are non-neuronal cells that provide support and protection for neurons in the nervous system. They also play a role in neural communication and can influence neuronal signaling. Axons, dendrites, and myelin cells are all types of neurons, not non-neuronal support cells.

Question 10

In a roller-blading mishap,Wendy fell down and injured the very back of her head.Which of her senses is most likely impaired

Accepted Answer

Since Wendy injured the back of her head, the occipital lobe of her brain is most likely affected. The occipital lobe is responsible for processing visual information, so impaired vision is the most likely outcome of the injury.

Question 11

According to your text,our brains are most adaptable during:

Accepted Answer

The text states that "our brains are most adaptable during early childhood, as synapses are forming and being pruned most rapidly during this time".

Question 12

A monkey makes an involuntary gesture when a portion of its brain is electrically stimulated.The area of the brain that was most likely stimulated is the:

Accepted Answer

The motor cortex controls voluntary movements, and electrical stimulation of this area would likely result in involuntary gestures. The sensory cortex receives and processes sensory information, the amygdala is involved in emotion and memory, and the occipital lobe is primarily involved in visual processing.

Question 13

The process by which the brain responds to experience or damage is termed ___________.

Accepted Answer

Neuroplasticity refers to the brain's ability to change and adapt in response to experience or damage. This includes the growth of new connections between neurons (neurogenesis) and the ability of neurons to change their connections (neuromutability or neuroflexibility). However, neuroplasticity is the most commonly used term to describe this process.

Question 14

Which of the following defines neuroplasticity

Accepted Answer

Neuroplasticity refers to the brain's ability to adapt to the effects of experience or damage, including the ability to form new neural connections and reorganize existing ones. Options A, B, and C describe the lateralization of brain function and the specialization of each hemisphere, which are separate concepts from neuroplasticity.

Question 15

Your text suggests that the correlation between the surface area of the cortex and intelligence is probably:

Accepted Answer

The text states that "research has suggested that there is a positive correlation between the surface area of the cortex and intelligence." Therefore, the most likely choice is D, positive.

Question 16

Below the frontal lobe is the _______ lobe.

Accepted Answer

The temporal lobe is located below the frontal lobe, primarily involved in processing auditory information and encoding memory.

Question 17

The "new brain" is the:

Accepted Answer

The "new brain" refers to the cerebral cortex, which is the outermost layer of the brain and is responsible for higher cognitive processes such as thinking, reasoning, and decision-making. The hindbrain (A) and cerebellum (D) are involved with basic bodily functions such as balance, movement, and breathing. The limbic system (B) is involved in emotions and memory. While important, these areas are not considered part of the "new brain."

Question 18

Which of the following defines contralateral control

Accepted Answer

Contralateral control is the phenomenon where the left side of the brain is responsible for controlling the movement and receiving sensory information from the right side of the body, and the right side of the brain is responsible for controlling the movement and receiving sensory information from the left side of the body. This means that the brain hemispheres control the opposite side of the body. Choice B describes lateralization, Choice C describes functional specialization, and Choice D describes neuroplasticity.

Question 19

In which lobe is the motor cortex located

Accepted Answer

The motor cortex is located in the frontal lobe of the brain. It is responsible for planning, executing, and controlling voluntary movements in the body.

Question 20

Which of the following is NOT one of the functions of glial cells

Accepted Answer

Glial cells do not communicate messages within the nervous system. This is the primary function of neurons. Glial cells provide support and protection to neurons, as well as aiding in the communication of messages through regulation of neurotransmitters and nourishment of nerve cells.
