Origins of NSC
What difference is there between dualism and monism?
Dualism is where the mind and body are separate (Plato and Descartes), monism is where the mind and body are the same entity?
Which part of the neuron integrates/ combines signals from the dendrites
the soma
What CNS protection is described as “cling wrap”?
Which behavior is implicated in the myelination process that moves rostrally?
Teenagers’ impulsivity
Which NT is excitatory and which is inhibitory?
Glutamate; GABA
What is the difference between the reticulum theory and the neuron doctrine?
RT proposed nervous system is a continuous network of cells, while the ND stated that it is made of discrete cells with gaps in between.
The most common type of neuron is
multipolar
What is the difference between fMRI and PET scan?
fMRI detects blood flow/oxygenation without any use of dye while PET scan uses radioactive chemicals to shows brain function
The entire nervous system develops from which outermost cell layer of the embryo?
Ectoderm
The idea that the closer in time the potentials arrive has a greater impact on the likelihood of producing an action potential is known as
Temporal summation
Which philosopher saw the heart as the seat of the mind and the brain as a cooling system for the blood?
Aristotle
What do oligodendrocytes do and what other glia is similar that’s produced in the peripheral nervous system?
It creates the myelin sheath on the axon and Schwann cells
A ganglion is
a cluster of cell bodies within the PNS
What structures are found at the tips of growing axons to guide them toward their target cells during circuit formation?
Growth Cones
What is the mesolimbocortical pathway and which neurotransmitter does it transport?
VTA to nucleus accumbens + cortex; dopamine
Who used staining to see individual cells?
Ramon y Cajal

auditory inputs and memory formation
Our "first brain" in human evolution which contains:
diencephalon: powers reflexive control of our behavior
thalamus, hypothalamus, pineal gland
What is the correct order of nervous system development?
1.Neurogenesis
2.Cell Migration
3.Cell Differentiation
4.Circuit Formation
5.Neuronal Cell Death
6.Synaptic Rearrangement
What is the difference in the synthesize of classical neurotransmitters, neuropeptides, and gas/lipid neurotransmitters?
synthesized from dietary precursors that cross BBB; synthesized in the soma/ packaged in large vesicles and then transported down the axon to the terminals; produced outside axon terminals (mostly dendrites) and not held in vesicles
Is phrenology an entirely reliable source to indicate someone’s character?
No, it only helped start localizing functions for the brain in the early ages, not to base someone off of

At approximately 25 days of development, the rostral portion of the neural tube forms three buds. Which of these is the midbrain and forebrain, respectively?
Mesencephalon, Prosencephalon
Neuropeptides are involved in
analgesia and reward
