molecule to the electrical and chemical properties of the brain.
B. Understanding the brain is a focused area in natural science with the brain serving as the common
point of focus.
C. Understanding the brain requires the analysis of one approach at a time to yield a new synthesis.
D. Understanding the brain requires the study of the different species of the brain. - Answer-A.
Understanding the brain requires knowledge about many things, from the structure of the water
molecule to the electrical and chemical properties of the brain.
A neuroscientist investigates how different neural circuits in the brain analyze sensory information, form
perceptions of the external world, make decisions, and execute movements. At what level of analysis is
this research conducted? Choose the correct option.
A. Cognitive neuroscience level
B. Cellular neuroscience level
C. Molecular neuroscience level
D. Systems neuroscience level - Answer-D. Systems neuroscience level
,At which level of analysis do neuroscientists study the different types of neurons and their functions?
Choose the correct option.
A. Cellular neuroscience
B. Cognitive neuroscience
C. Molecular neuroscience
D. Behavioral neuroscience - Answer-A. Cellular neuroscience
What is the rationale behind the use of animal models to understand the human brain?
A. The nervous systems of different species of animals and humans share many common mechanisms.
B. Brain mechanisms that motivate any reaction are identical in animal and human brains.
C. Animal brains are identical to human brains but only smaller in size.
D. Animal brains are easier to obtain than human brains. - Answer-A. The nervous systems of different
species of animals and humans share many common mechanisms.
What is the difference between replication and verification?
A. Replication can only be done once whereas verification can be done many times.
B. Replication and verification are not essentially different.
C. Replication tests a hypothesis whereas verification rechecks the hypothesis.
D. Replication is repeating the experiment in other subjects to rule out the possibility of chance. In
verification, the experiment is repeated and the same observations are obtained by any scientist
following the same protocol as the original observer. - Answer-D. Replication is repeating the
experiment in other subjects to rule out the possibility of chance. In verification, the experiment is
repeated and the same observations are obtained by any scientist following the same protocol as the
original observer.
An example of an observation in the scientific process would be (select all that apply):
A. cutting nerve fibers to see what happens to movement
B. repeating an experiment on a different group of patients
, C. verifying an observation
D. lesioning the hippocampus to see what happens to memory - Answer-A & D

A. True
B. False - Answer-B. False
Which of the following statements are true? Select all that apply.
A.Living conditions of animals should be appropriate for their species and contribute to their health and
comfort.
B.Proper use of animals, including the avoidance or minimization of discomfort, distress, and pain when
consistent with sound scientific practices, is imperative.
C.Procedures involving animals should be designed and performed with due consideration of their
relevance to human or animal health, the advancement of knowledge, or the good of society
D.Investigators and other personnel do not need any training to conduct animal experiments.
E.Animals selected for procedures should be of an appropriate species, quality, and the minimum
number required to obtain valid results. - Answer-A, B, C, & E
