Selectivity to slowly rising stimuli in frog auditory neurons
|| Many acoustic communication signals, including phonemes of human
speech, are differentiated in the time from onset to peak amplitude
(rise time). Correspondingly, there are neurons that respond selectively
to slowly rising pulses. We investigate possible mechanisms that
underlie this selectivity.
I will present methods for input reconstructions from in vivo data as well as
three computational models of possible slow rise-time selectivity mechanisms.
Finally, I will show model predictions, which will allow to
distinguish between the proposed mechanisms as more data becomes
