Question 1

Which of the following best describes the difference between correlational studies and experimental studies in behavioral neuroscience?

Accepted Answer

Experimental studies provide evidence for causality, while correlational studies do not.

Question 2

In an experiment testing the effect of a new drug on memory performance in mice, what is the independent variable?

Accepted Answer

The dose of the new drug administered to the mice

Question 3

Which research method would be most appropriate for identifying the connections between different brain regions in a living animal?

Accepted Answer

Tract tracing with a chemical tracer

Question 4

A scientist wants to study the effect of visual stimuli on neural activity in the occipital cortex. Which method would provide the best temporal resolution?

Accepted Answer

Electroencephalography (EEG)

Question 5

Which of the following is a key advantage of using animal models in neuroscience research?

Accepted Answer

Animal models allow for more invasive techniques such as ablation and optogenetics.

Question 6

What is the main purpose of a control group in an experimental design?

Accepted Answer

To account for confounding variables and provide a baseline for comparison.

Question 7

Which imaging technique is best suited for measuring the fixed anatomy of the brain?

Accepted Answer

Structural MRI

Question 8

A researcher uses optogenetics to activate specific neurons in a mouse brain. What is the primary advantage of this technique?

Accepted Answer

It allows for millisecond temporal precision in manipulating neuronal activity.

Question 9

Which of the following best defines reductionism in neuroscience?

Accepted Answer

The attempt to explain complex events in terms of simpler, lower-level ones.

Question 10

Which method is most appropriate for mapping brain function before epilepsy surgery?

Accepted Answer

Electrocorticography (ECoG)

Question 11

A study measures the relationship between hours of sleep and reaction time in college students without manipulating any variables. What type of study is this?

Accepted Answer

Correlational study

Question 12

Which of the following techniques is considered invasive and typically limited to animal models or medical need?

Accepted Answer

Single-cell recording

Question 13

What is the main difference between in vivo and in vitro experiments?

Accepted Answer

In vivo experiments are performed in living organisms, while in vitro are performed on cultured cells or isolated molecules.

Question 14

Which of the following methods would be best for identifying the expression of a specific protein in neurons?

Accepted Answer

Immunohistochemistry

Question 15

A researcher wants to silence a specific population of neurons temporarily in a mouse. Which technique should they use?

Accepted Answer

Chemogenetics (DREADDs)

Question 16

Which of the following is a key feature of functional MRI (fMRI)?

Accepted Answer

It detects changes in blood oxygenation related to neural activity.

Question 17

What is the main limitation of EEG compared to MEG?

Accepted Answer

EEG has lower spatial resolution than MEG.

Question 18

Which of the following best describes a crossover study design?

Accepted Answer

Each participant receives both treatments in a sequential order.

Question 19

A scientist uses CRISPR/Cas9 to modify a gene in mice and observes changes in behavior. What type of genetic manipulation is this?

Accepted Answer

Gene editing

Question 20

Which of the following methods is best for studying the dynamics of the brain in action?

Accepted Answer

Functional imaging (e.g., fMRI, PET)
