A model of baroreceptor transduction of blood pressure


A model of baroreceptor transduction of blood pressure consisting of
   i.)   A linear viscoelastic description of arterial wall strain taken from [1]
   ii.)  A linear viscoelastic coupling of arterial wall strain to nerve ending 
         strain from [1]
   iii.) A Hodgkin-Huxley type neuron model consisting of voltage gated sodium and 
         potassium channels with kinetics parameterized by [2], a mechanosensitive 
         ion channel and a sodium leakage current.
   iv.)  The action potential peaks are detected and an instantaneous firing rate is 





The equations for this model may be viewed by running the JSim model applet and clicking on the Source tab at the bottom left of JSim's Run Time graphical user interface. The equations are written in JSim's Mathematical Modeling Language (MML). See the Introduction to MML and the MML Reference Manual.
