, COMPREHENSIVE EXAMINATION Questions 1 – 35
1. What is neuroscience?
A. The study of only the brain's anatomical structures
B. The study of all aspects of nervous system function from molecular to cognitive levels
C. The study of psychological disorders and their treatments
D. The study of only neuron electrical activity
CORRECT ANSWER B — The study of all aspects of nervous system function from molecular to
cognitive levels.
RATIONALE Neuroscience is an inherently multidisciplinary field that examines the nervous
system at every level of analysis — from genes and molecules to cells, synapses,
neural circuits, systems, behavior, and cognition. It integrates biology, chemistry,
physics, psychology, and computer science. This breadth allows researchers to
understand both how individual neurons function and how they collectively
produce complex behaviors, emotions, and consciousness. The goal is to derive
general principles that apply across species.
,2. What are the main levels involved in building a nervous system, from most basic to most
complex?
A. Cells, Molecules, Genes, Neural Circuits, Synaptic Connections, Behavioral Systems,
Cognitive Input
B. Genes, Molecules, Cells, Synaptic Connections, Neural Circuits, Behavioral Circuit
Systems, Cognitive Input
C. Cognitive Input, Behavioral Systems, Neural Circuits, Cells, Molecules, Genes
D. Molecules, Genes, Neural Circuits, Cells, Synaptic Connections, Behavioral Systems
CORRECT ANSWER B — Genes → Molecules → Cells → Synaptic Connections → Neural
Circuits → Behavioral Circuit Systems → Cognitive Input.
RATIONALE The nervous system is built hierarchically: (1) Genes encode the molecular
machinery. (2) Molecules (neurotransmitters, receptors, ion channels) mediate
cellular function. (3) Cells (neurons and glia) form the basic units. (4) Synaptic
connections allow communication between cells. (5) Neural circuits integrate
multiple synaptic connections into functional networks. (6) Behavioral circuit
systems produce coordinated behaviors. (7) Cognitive input represents the
highest level — thoughts, emotions, and consciousness emerging from these
systems. Each level constrains and enables the level above it, creating the
complexity of brain function.
, 3. What is the goal of neuroscience research across different species?
A. To prove that humans are fundamentally different from all other animals
B. To derive general principles of the nervous system that apply across species
C. To develop treatments only for human neurological disorders
D. To map every neuron in every species individually
CORRECT ANSWER B — To derive general principles of the nervous system that apply across
species.
RATIONALE Comparative neuroscience studies diverse species because fundamental neural
mechanisms are evolutionarily conserved. From the simple nervous system of C.
elegans (302 neurons) to the complex human brain (86 billion neurons), basic
principles of synaptic transmission, action potentials, neural circuit organization,
and plasticity are remarkably similar. Discoveries in animal models (mice, fruit
flies, jellyfish) have been foundational to understanding human brain function
and developing treatments for neurological and psychiatric disorders.
4. Which of the following animals are commonly used in neuroscience research?
A. Only humans and chimpanzees
B. Mouse, C. elegans, Monkey, Jellyfish, Drosophila melanogaster, and Human
C. Only rodents and primates
D. Only vertebrate animals
CORRECT ANSWER B — Mouse, C. elegans, Monkey, Jellyfish, Drosophila melanogaster, and
Human.
RATIONALE Neuroscience uses a wide range of model organisms, each offering unique
advantages: (1) Mouse — mammalian brain with genetic tools for manipulating
specific genes. (2) C. elegans (roundworm) — exactly 302 neurons, fully mapped
connectome. (3) Monkey — closest to human brain organization for studying
higher cognition. (4) Jellyfish — simple nervous system for studying basic neural
principles. (5) Drosophila melanogaster (fruit fly) — powerful genetic tools and
complex behaviors. (6) Human — studied through neuroimaging,
neuropsychology, and post-mortem analysis. This diversity allows triangulation
of findings across species.
