Cultured Kenyon cells from the mushroom body of the honeybee, Apis mellifera, show a voltage-gated, fast transient K1 current that is sensitive to 4-aminopyridine, an A current. The kinetic properties of this A current and its modulation by extracellular K1 ions were investigated in vitro with the whole cell patch-clamp technique. The A current was isolated from other voltage-gated currents either pharmacologically or with suitable voltage-clamp protocols. Hodgkin- and Huxley-style mathematical equations were used for the description of this current and for the simulation of action potentials in a Kenyon cell model. The data of the A current were incorporated into a reduced computational model of the voltage-gated currents of Kenyon cells. In addition, the model contained a delayed rectifier K current, a Na current, and a leakage current. The model reproduces several experimental features and makes predictions. See paper for details and results.

Example use:

Start SNNAP (double click on the SNNAP.jar file)
click on "Run Simulation"
Then in the new window "File"->"Load Simulation"
browse to and load Kenyon_Ka_VC.smu file to load a simulation
then and click "Run Batch" and open Ka_VC.bch to generate
a figure similar to Fig 12 in the above publication
(see Fig12Model.jpg for what it should look like when done).
