tuning curves and post stimulus time histograms Flashcards
tuning curves
a plot that represents the tuning or frequency specificity of responses
what does CF means in relation to a tuning curve
characteristic frequency
what does it mean for a sound with a tuning curve
the sound will disappear after it has reaches the CF for the certain sound
how does a a high vs. low frequency affect the tuning curve action
playing a high frequency will trigger then goes through round window BUT with a low frequency, it has to pass through the whole area to get to the specific CF
upward spread of masking
low frequencies mask high frequencies more effectively and efficiently than high frequencies masking low
tuning curves are a great way to assess the ______ function
normal
what can a tuning curve map out
tonotopic organization
post-stimulus time histograms (PSTH)
plots the spikes of a neuron (neural firing)
-over time
-following a stimulus
PSTH are meant to plot for a ________ stimulus
specific
what does it mean by measuring post stimulus awareness
immediately after the stimulus, there will be a spike
-before the stimulus there will be a resting rate/resting potential
fusiform/pyramidal cell
spike, pause, then another build up
octopus cell
onset responsers
-resting rate, spike, resting rate again
primary like with notch
spike, plateau, then back down
stellate cell
sustained or chopper responses
-resting rate, onset and has a plateau but every now and then it is choppy
spherical and globular cell
primary like
-spike, plateau, drop off
