What kind of conclusion *couldn’t* be deduced from a PSTH?

20 points

time of maximal firing rate after stimulus onset

time of stimulus onset

if the neuron responds to the stimulus

differences between trials

Why do we use shift predictor in JPSTH?

20 points

to normalize the JPSTH to the joint baseline of the two neurons

to reduce the JPSTH only to the stimulus relevant information

to compute the correlation between the two neurons

to check possible excitatory relations between the two neurons

Given the following spike triggered average of a neuron in the igniting system of the Electrical Dragon, what stimulus will produce the maximal response of the neuron?

20 points

sine wave with amplitude of 220V and a frequency of 5 Hz

sine wave with amplitude of 220V and a frequency of 7.5 Hz

sine wave with amplitude of 220V and a frequency of 10 Hz

constant input of 220V

Given that the baseline firing rate of neuron is 10 spykes/sec which its linear kernel is [3,1,4], what is its estimated rate function to a stimulus of [1,3,4,6,7,8]?

20 points
