what does the color represent in the spectrogram? Answer: amplitude
or power (mV or uV)
where are we likely to see alpha waves? Answer: 10 Hz
can spectrograms and PSD plots be matched together? Answer: yes
what do EEG values represent? (6-80 Hz) Answer: firing rate
high frequency/ high amplitude waves will look like what? Answer: lots
of waves that are very tall and narrow- like very tall hills and steep
valleys
low frequency/ low amplitude waves will look like what? Answer: only a
couple of waves, which are very short and long. not tall or steep-
almost a straight line
how do you convert EEG amplitude into power? Answer: square the
value of amplitude
which conditions in the fly PD model contained DMSO Answer: all of
the conditions
rotenone effects: Answer: impairs mitochondria
