Metadata generic

• Authors: M Migliore
• Comments: K-a channel from migliore et al. (1999), model no. 2796 (from klee, ficker and heinemann (1995) as well as hoffman et al (1997)), modified by t brannon and y poirazi to account for hoffman et al (1997) proximal region kinetics. Used only in locations <100 microns from the soma and in the soma. It is not clear if kinetics have been altered from the ancestor model. Not used in main model implementation [found in not-currently-used folder]. 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: 8.029
