hc-3: Is there an explanation for missing spikecounts at 40 spks/s?

Posted by Tristan Stoeber at July 02. 2017

Hey crcns-community,

this example is taken from the hc-3 data set:

animal_id = 'ec014'
day = 29
session = 468

I separated each passage from one end to the other on the linear track, then i bin the track into 10 cm bins and count the spikes that occur in each bin for each passage. i divide the number of spikes by the time the animal was in that bin during each passage. I plot the number of spikes/s for each passage through a single bin as a single dot for two neurons. Because of the many passages I do get a distribution (see attachment). For potentially excitatory neurons, I observe that most cells never exceed 40 spks/s (first plot), for some interneurons (second plot), the 40 spks/s values are almost completely lacking. Is there some explanation for this, lets say in the filter settings or so? I have been searching intensively for a bug in my code, but without success.

thanks in advance,

tristan
