Question 1

Terminal buttons are the ends of axon that hold ______.

Accepted Answer

The answer of Terminal buttons are the ends of axon...

Question 2

The hypothalamus area of the brain is associated with basic emotions.To separate these emotions into emotional learning, fear, and memory, this information is transmitted by the amygdala.

Accepted Answer

The hypothalamus plays a role in basic emotions such as hunger, thirst, and sex drive. The amygdala is responsible for emotional learning, fear, and memory.

Question 3

The olfactory bulb is the primary organ in the brain for processing memory.

Accepted Answer

The primary organ in the brain for processing memory is the hippocampus, not the olfactory bulb. The olfactory bulb is mainly involved in the sense of smell.

Question 4

To a behavioral neuroscientist the brain is a complex assortment of separate areas and regions, each of which has its own unique function.

Accepted Answer

The answer of To a behavioral neuroscientist the brain is...

Question 5

Benzodiazepines are usually used because of their effects on anxiety, insomnia, and muscle relaxation.

Accepted Answer

Benzodiazepines are commonly prescribed for their anxiolytic (anxiety-reducing), sedative/hypnotic (insomnia-inducing), and muscle relaxant effects.

Question 6

Engram is the hypothetical physical unit of ______ of a memory.

Accepted Answer

The answer of Engram is the hypothetical physical unit of...

Question 7

The electrochemical process of transmission in an axon is known as action ______.

Accepted Answer

The answer of The electrochemical process of transmission in an...

Question 8

Magnetoencephalography (MEG) uses an electrical sensor to detect small magnetic fields produced by electrical activity in the brain.

Accepted Answer

Magnetoencephalography (MEG) uses highly sensitive devices called SQUIDs (superconducting quantum interference devices) to detect the small magnetic fields produced by neuronal activity, not electrical sensors.

Question 9

Engram is the hypothetical physical unit of storage of a memory.

Accepted Answer

Engram is a term used in neuroscience to refer to the physical and biological basis of a memory, essentially the physical storage unit for memories in the brain. However, it is important to note that the existence of engrams is still a matter of debate and research in the field of neuroscience.

Question 10

Retrograde amnesia is the inability to tolerate benzodiazepines during sleep-enhanced episodic memory.

Accepted Answer

Retrograde amnesia refers to the loss of memories that occurred before the onset of amnesia. It is not related to the ability to tolerate benzodiazepines or sleep-enhanced episodic memory.

Question 11

Intracranial EEGs measure brain activity when electrodes are placed directly on the surface of the brain.

Accepted Answer

Intracranial EEGs (iEEGs) are a type of electroencephalogram that measures brain activity by placing electrodes directly on the surface of the brain.

Question 12

The parts of the neuron that receive sensory receptors are called ______.

Accepted Answer

The answer of The parts of the neuron that receive...

Question 13

Memory can be enhanced, however, to date, no drug has been shown to improve memory efficiency in normal adults.On the other hand, there is no doubt that some drugs prevent the formation of new memories.The only prescription drugs available to improve memory are chloinergics.

Accepted Answer

While no drug has been shown to improve memory efficiency in normal adults, cholinergics are prescription drugs that can improve memory. However, some drugs can prevent the formation of new memories.

Question 14

Deep brain stimulation does not require an implanted device.

Accepted Answer

Deep brain stimulation (DBS) requires an implanted device, typically a small electrode that is surgically placed into specific regions of the brain. The electrode is connected to a device called a neurostimulator, which is implanted under the skin of the chest or abdomen. The neurostimulator sends electrical impulses to the brain to help regulate abnormal activity and alleviate symptoms of conditions such as Parkinson's disease or essential tremor.

Question 15

It is suggested that music may be good at eliciting a strong connection between it and memory.

Accepted Answer

Various studies have suggested that music can activate multiple regions of the brain, including those involved in memory processing. This may explain the strong connection between music and memory.

Question 16

Diffusion tensor imaging (DTI) is another MRI technique.

Accepted Answer

DTI is a type of MRI technique that is used to assess the orientation, shape, and integrity of white matter tracts in the brain.

Question 17

The thalamus is an area of the brain heavily connected to other areas of the brain.It appears to serve as a routing center, however, this routing center must have connected relay points to human memory circuits.The routing centers are known as diencephalons.

Accepted Answer

The statement accurately describes the thalamus as a heavily connected area of the brain that serves as a routing center, with connected relay points known as diencephalons.

Question 18

The medial temporal lobe is associated with higher emotions, decision-making, metacognition, and memory.Damage to this area affects the fight or flight emotional response.This response can be associated with the prefrontal cortex.

Accepted Answer

The medial temporal lobe is primarily associated with memory formation. The fight or flight response is more directly linked to the amygdala, which is part of the limbic system, and the prefrontal cortex is involved in decision-making and moderating social behavior, not directly triggering the fight or flight response.

Question 19

Positron Emission Tomography (PET) allows scientists to get a detailed image of a living human brain without damaging living tissue.It does involve injecting a small amount of radioactive substance into a person's blood, which does have potentially negative effects.

Accepted Answer

PET does involve injecting a small amount of radioactive substance into a person's blood, which can have potentially negative effects.

Question 20

Sudden and devastating injuries to the brain are called ______ brain injuries.

Accepted Answer

The answer of Sudden and devastating injuries to the brain...
