spectrogram graph that measures time vs frequency- colored graph
PSD plot graph that measures frequency vs amplitude- graphs the waves
what does the colored bar on the side of the spectrogram measure? amplitude
what do the pink splotches in the back of the spectrogram represent? noise
what is the x axis of a spectrogram? time (seconds or minutes)
what is the y axis of a spectrogram? frequency (Hz)
what is the x axis of a PSD plot? frequency (Hz)
what is the y axis of a PSD plot? amplitude (mV or uV)
what does the color represent in the spectrogram? amplitude or power (mV or uV)
where are we likely to see alpha waves? 10 Hz
can spectrograms and PSD plots be matched together? yes
what do EEG values represent? (6-80 Hz) firing rate
high frequency/ high amplitude waves will look like what? lots of waves that are very tall
and narrow- like very tall hills and steep valleys
