Models considered in this paper

ModelSMRP?Power ratio in SMRP range?
Noisy, leaky integrate-and-fire (NLIF)NoNo (except for low contrasts)
Poisson-resampled spike trainYesYes
Modified Poisson processYesYes
Modulated Poisson processYesYes
Modulated gamma processYesYes
Non-leaky integrate-and-fireYesYes
SMRP with fixed absolute refractory periodNoYes (except for excessively long refractory periods)
• For each model, we ask two questions: (1) Is the model a simply modulated renewal process (SMRP)? and (2) Does the power ratio fall in the range expected for an SMRP?
