receptor potential module. It supplies input to the inner hair cell synapse
models, e.g. IHC_Meddis86a: Inner Hair Cell Synapse, page 197 or IHC_Carney:
Inner Hair Cell Synapse (1993), page 172.

See figure [118] on page 217. At the time of writing, the PC version encounters an error calculating the last two analysis reading for this test program (with an "exp overflow error"). No attempt has yet been made to address this problem, as the model is still in development. Also the problem did not occur in the Macintosh and UNIX testing. There is no problem with the previous calculated readings when the program is run, calculating only the first eight readings.
