The klt.mod
file implements a computational model describing the kinetics of the low-threshold transient potassium current found in ventral cochlear nucleus neurons, particularly in "Type I" cells. These neurons are typically stellate or multipolar cells. The model captures the dynamics of a specific type of potassium channel, believed to be mediated by Kv4.2 subunits, but not definitively proven to be so.

): The model references a standard potassium reversal potential, critical for defining the driving force for potassium ion flow across the membrane.The klt.mod
file models the low-threshold potassium conductance in cochlear nucleus neurons, capturing the essence of transient potassium currents that influence neuronal firing properties. By simulating the kinetics of potassium channel activation, inactivation, and their temperature dependence, the model allows for exploration and understanding of how these currents contribute to the auditory processing capabilities of cochlear nucleus neurons.
