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 available.
