These stimuli were 20 repeated trials of 84-second flashes of orientated drifting gratings presented at0.05 cycles perdegree and2Hz. We simulate 20 trials of 24 Poisson neurons. We next perform inference on these simulated data using both models. To select the dimensionality for this paper, we proceed by first analysing each single region, andthen usethatinformation totestthemulti-region model. That is, first we identify the optimal signal dimensionality of the V1 data alone and to the optimal signal dimensionality oftheALdataalone, determined viaaveraging overfive-fold cross validation.
