ModelDB: Febrile seizure-induced modifications to Ih (Chen et al 2001)

Febrile seizure-induced modifications to Ih (Chen et al 2001)

Accession: 8284

Modeling and experiments in the paper Chen K,Aradi I, Thom N,Eghbal-Ahmadi M, Baram TZ, and Soltesz I (2001) support the hypothesis that modified Ih currents strongly influence inhibitory inputs in CA1 cells and that the depolarizing shift in Ih activation plays a primary role in this process. Please see the paper for details. Some modeling details are available at http://www.ucihs.uci.edu/anatomy/soltesz/supp.htm Correspondance should be addressed to isoltesz@uci.edu (modeling was done by Ildiko Aradi, iaradi@uci.edu)

Ccellsyn.hoc - CONTROL cell
HTcellsyn.hoc - HT cell

To simulate these cells, we need all of the following mechanisms:

ichan.mod - Na and K channel kinetics in HT and Control cells
hyperso.mod - HT and Control Ih channels in the soma
hyperde1.mod - HT and Control Ih channels in the proximal dendrites
hyperde2.mod - HT and Control Ih channels in the middle dendrites
hyperde3.mod - HT and Control Ih channels in the distal dendrites
ppsyn.mod - inducing synaptic currents in HT and Control cells
