Take home quiz 2.
This is a take home, open book and collaborative quiz. Each question can have multiple correct answers,
you need to circle all correct answers. If you are partially correct but miss one or more correct answers
you will receive proportional credit. Short answers have equal value. Do not write outside the box,
writing outside the box will not be considered. If you detect a flaw in the questions I will remove it from
the grading and the class will get full credit for that item. The completed quiz is due by class time on
September 17th
C.
1) Homosynaptic and heterosynaptic plasticity differ in that:
a. Heterosynaptic plasticity drives homosynaptic depression
b. Homosynaptic plasticity is only observed in insects and other invertebrates
C. Homosynaptic plasticity can result in depression of the postsynaptic response
d. Heterosynaptic plasticity can result in depression of the postsynaptic response
e. Homosynaptic plasticity is the basis of facilitation and habituation
f. Heterosynaptic plasticity can result in depression of the presynaptic response
g. Heterosynaptic plasticity requires an intervening neuron to mediate change in the
postsynaptic response
h. Heterosynaptic plasticity can result in inhibition of the postsynaptic response
i. None of the above
2) According to lecture discussion, oscillations, which can be measured by electrodes:
a.
Are often referred to as brainwaves or local field potentials
b. Are the consequence or byproduct of the subthreshold (IPSPs and EPSPs) and spiking
activity in a region around the electrode.
Are not a means for communication between brain areas, that is, there are no
oscillation receptors
d. Are the best indicator of the spiking behavior of individual neurons.
e. None of the above
3) To establish a causal relationship between a neuron (or neurons) and a specific behavior, what
all does a neuroscientist need to establish:
a. Simply a correlation between neuron (or neurons) and a specific behavior but nothing
more.
b. Demonstrate that even if you suppress the neurons activity the behavior can persist
C. Show that activating the neuron (or neurons) is sufficient to drive a specific behavior
d. Demonstrate that suppressing the neuron (or neurons) activity renders the animal
incapable of producing the behavior
e. None of the above
4) According to the textbook, the stomatogastric ganglion:
Is responsible for driving the pyloric but not the gastric rhythm
b. is an uncomplicated neural network
C. Is responsible for driving both the pyloric and gastric rhythms
d. Drives both escape behaviors and defense responses
e. is an example of a central pattern generator
f. Is composed of only 30 neurons
g. None of the above
5) Finish the sentence echo locating bats determine the absolute size of a target by.
a.
6) The FM sweep call and echo is best suited to:
a. Allow the chasing bat to determine if a prey target is traveling relatively faster and
getting away
b. Is ideal to handle doppler shift
C. Is a broadband in its frequency content
d. is best for long distance detection of prey items.
e. Discriminate low from high frequency
f. Determine absolute size of a target
8.
Determine textural features of the target
h. None of the above
7) According to Moss and Sinha, a complex circuit of interconnected brain nuclei control the timing
and spectro-temporal details of bat vocalizations and that many of these brain regions receive
input from auditory sensory nuclei
a. True
b. False
8) CF bats
Produce a relatively narrow band frequency call
b. Have an enhanced sensitivity that manifests as an increased density of the hair cells in
the region of the cochlea that encodes the returning echo
Have an enhanced sensitivity that manifests as a physical elongation of the region of the
cochlea that encodes the returning echo
d. Can detect prey targets from a greater distance than FM bats
e. Cannot detect prey targets from a greater distance than FM bats
f.
Use doppler shift information to modulate their calls
9) The inferior colliculus
Responds only to very large amplitude calls
b. Responds to stimulus pulses that replicate the call and returning echo
C. Respond the same independent of the amplitude of the call or the echo
d. Faithfully represents the timing of the call and echo independent of their amplitude
e. Individually respond to the entire FM sweep
f. Require a population response to encode the entire FM sweep
10) In the FM-FM region of the cortex cells in specific columns respond to:
A specific combination of pulse echo delays
b. Prefer specific amplitudes
C. Encode the relative velocity of the target
d. Depending on the subregion, respond to the call and specific harmonics of the echo
e. the acoustic fovea frequencies only
f. Only respond to specific frequencies
C.
a.
a.
