The provided code is a computational model describing the dynamics of h-channels (hyperpolarization-activated cyclic nucleotide-gated channels or HCN channels) in neurons. H-channels play critical roles in regulating neuronal excitability and rhythmic activity. The model focuses on the somatic Ih current kinetics in two scenarios: control animals and those with heightened excitability due to complex febrile seizures.

factor representing the temperature dependence of the ion channels. It models how channel kinetics are affected by changes in temperature, reflecting physiological realities such as febrile conditions.inf
) and time constants (tau
) are voltage-dependent, capturing the behavior of h-channels in response to changes in the membrane potential, crucial for simulating neuronal excitability in different thermal states.This code provides insights into how changes in h-channel parameters alter neuronal excitability, particularly in the context of thermal changes and seizure activities. By focusing on the differential behavior of fast and slow components under control and hyperthermic conditions, it seeks to model the biophysical basis of seizure-related changes in neuronal function.
