Metadata generic

• Authors: Y Poirazi
• Comments: Ca r-type (hvam) channel with medium threshold for activation used in distal dendritic regions, together with calh.mod, to help the generation of ca2+ spikes in these regions, uses channel conductance. Written by y poirazi nov 2000. Adapted from magee and johnston (1995), modified to account for ca2+ spikes. No model db ancestors. This is a modeling study, and the animal model is considered to be rat. The authors compare the model to experimental results mostly in rats (e.g. Magee 1998, spruston et al. 1995) and the morphology used is also from rat (2 months old, cannon et al. 1998, n123). Channel kinetics come from various sources.
• Runtime: 7.409
• Temperature: Model has temperature dependence. Simulations were done at 34 deg C.
