NEU 311L Midterm Questions With Complete Solutions
___ in K+ concentration = ___ drive for K+ to leave cell -->
buildup of ___ charge, resulting in ____ in MP Correct Answer
increase
decrease
positive
decrease
are we likely to see other EEG waves at the same frequency as
alpha waves? Correct Answer no
can spectrograms and PSD plots be matched together? Correct
Answer yes
conditions and concentrations for fly PD model Correct
Answer control
rotenone (62.5uM)
rotenone (62.5uM) + melatonin (5mM)
melatonin (5mM)
high frequency/ high amplitude waves will look like what?
Correct Answer lots of waves that are very tall and narrow-
like very tall hills and steep valleys
how do authors report EEG signal strength? Correct Answer
power
how do you convert EEG amplitude into power? Correct
Answer square the value of amplitude
, how does the amplitude and frequency band in the spectrogram
compare to the values you obtained from the PSD plot for the
same record? Correct Answer they are very similar
increasing extracellular potassium will significantly _____ RMP
of the cell Correct Answer decrease
low frequency/ low amplitude waves will look like what?
Correct Answer only a couple of waves, which are very short
and long. not tall or steep- almost a straight line
PSD plot Correct Answer graph that measures frequency vs
amplitude- graphs the waves
rotenone effects: Correct Answer impairs mitochondria
increases free radicals
spectrogram Correct Answer graph that measures time vs
frequency- colored graph
stat value that compares significance Correct Answer p value
was almond oil independent or dependent? Correct Answer
dependent
was lavender oil independent or dependent? Correct Answer
independent
was lavender oil the control or experimental variable? Correct
Answer experimental
