NEU 402 Exam 1 || 100% Accurate Answers.
Define behavior correct answers a detailed act or process -anywhere from simple acts to complex
results or function
Dualism vs Monism correct answers Dualism: the mind and brain (body) are separate
Monism: the mind is a product of brain activity
define hereditary trait correct answers trait is passed down genetically to the next generation
~referred to as "nature"
ex: presence of the lactase gene
define learned trait correct answers trait is passed down to the next generation in a non-genetic
way ~nurture or environment
ex: daily consumption of lactose
What is CRISPR technology? correct answers Clustered Regularly Interspaced Short
Palindromic Repeats; refers to a family of DNA sequences found in the prokaryotic genome and
is most known as a genetic tool to edit genes; requires the use of an enzyme (caspase) which has
the ability to edit, remove, or replace DNA sequences with the help of a guide RNA
What is the human genome project? correct answers began in 1990 and the aim was to sequence
the entire human genome ~map location of all genes on human chromosomes and determine the
order of bases within each gene; project was completed in 2006
According to somatosensory homunculus, what area is most represented? correct answers hands
and face; indicates that tehre are more sensory receptors in these areas
The superior colliculi are part of the? correct answers The Midbrain
Which area from the visual path is common to the auditory path? correct answers Thalamus
Which area if not subjected to hemispheric specialization?
a. planum temporale
b. Broca's area
c. somatosensory cortex
d. wernicke's area correct answers c. Somatosensory cortex
When reading a written word, the first region to be activated in the brain is correct answers
visual area
Which one does not occur int he adult brain?
a. regeneration of damaged axons
b. neurogenesis
c. compensation
d. synaptic plasticity correct answers a. regeneration of damaged axons
, a chemoattractant guidance factor is primarily involved in correct answers sprouting of filopodia
a chemorepellent guidance factor is primarily involved in correct answers axon growth collapse
Where is CSF produced? correct answers choroid plexus (specialized ependymal cell) within
each ventricle and flows undirectionally (each ventricle adds more CFS along the way)
What is the path of cerebral spinal fluid? correct answers lateral ventricles -> intraventricular
foramen -> third ventricle -> cerebral aqueduct -> fourth ventricle -> subarachnoid space -> two
lateral apertures -> one median aperture (midline) -> then it surrounds/cushions the brain and
spinal cord
What structures in the basal ganglia play a large role in motor control? correct answers caudate
nucleus
putamen
globus pallidus
substantia nigra
Which part of the brain is responsible for our most automatic functions such as the regulation of
heart rate and respiratory rate? correct answers The brainstrem (comprised of the midbrain, pons,
and medulla)
Describe the function of the corpus callosum correct answers brain's largest set of commissural
fibers (axons/white matter tracts) that allows for communication between the left and right
hemispheres of the brain
What is agenesis of the corpus callosum? correct answers individuals are born with either partial
or totally lacking corpus callosums (roughly 1 in every 4000)
The language center of the brain is in which hemisphere? correct answers left hemisphere
Words in the right visual field can easily be read and communicated by split-brain patients,
whereas words in the left visual field cannot. Explain correct answers info from the left visual
field is processed by the right visual cortex, but cannot travel to the left side to be verbalized;
info in the right visual field is processed by the left visual cortex and is already on the same side
as the language center, so info does not need to cross sides to be verbalized
What is the "right ear advantage"? correct answers subjects will only repeat info from the right
ear when conflicting info is presented to the left and right ear; follows the idea that info from one
ear will be processed by the auditory cortex on the other side; left ear -> right auditory cortex,
info has to cross hemispheres to be verbalized; right ear -> left auditory cortex, info does not
have to cross hemispheres to be verbalized and it reaches language center faster
