adaptive filtering

[frederic manseau]

Hello,

I am a researcher in neuroscience working on cortical interneuronal network
connectivity and dynamics.

I have electrophysiological recordings of neurons which spike at more or
less the same time (with some jitter) over multiple episodes when stimulated
repeatedly with the same injected current waveform.

 

After detection of the spike timing, I can construct Peri-stimulus histogram
(PSTH):

 

I would like to smooth the distribution of these PSTH using an "adaptive
filter" (which I think should be centered on each time step and widened to
capture something like 5-10 spikes)

 

Does anyone have any idea of how to do that with Octave ?

 

p.s. I tried to insert some figures in my email to make my question clearer
but the email bounced back, so I guess I cannot put figures

 

Thanks in advance for your answers.

Best regards,

 

Frederic Manseau (Ph.D.)
