// Ri18 model that includes Ih (Kole 2006) and reproduces dendritic spikes in
// response to somatic AP burst. This version includes Schaefer et al mod files
// and Maarten's Ih mod file and init_vm. The firing threshold was set to -63 mV
// (Gulledge 2003). Changes to Ca channels were adopted from Schaefer et al (2003).
// No change to it channel parameters. No slow Ca channels (HVA) were included.
//
// Simulation plots distal NMDA conductance as in figure 8 in Letzkus (2006)
// J Neurosci 26(41):10420–10429.
