The following programs JPCalcW , MemPotW and ArtMemW and MemCableW now  come as full Windows programs. In each case, they can be run under Windows XP, Vista, 32-bit Windows7 and under 64-bit Windows 7, provided they are run under Windows XP Mode (free for Windows 7; see  JPCalcW ). They can also be run in  Macintosh computers, provided they have fully compatible Windows emulation packages. These programs are each computer-aided learning (CAL) programs, which are aimed to simulate actual experiments and teach some difficult concepts in physiology.  Free demonstration versions of each of the programs are available. Further information may be obtained either from this Web page or by contacting Professor Peter H. Barry (p.barry@unsw.edu.au) of the Dept of Physiology, School of Medical Sciences, Faculty of Medicine at the University of New South Wales.  For information about him and his research and other interests click on  Professor Peter H. Barry.

To order any of the above programs, contact Peter Barry directly by email at p.barry@unsw.edu.au 

RESEARCH/TEACHING

For general information about the Liquid Junction Potential Calculator, JPCalcW, and Liquid Junction Potential Calculations, ion mobility listings, ion mobility-conductivity relationship, JPCalcW manual and demo download (a DOS version only), correction in AxoBits 39 article, etc., click here

Please note sign corrections in the article on liquid junction potentials in the original printed and original pdf version of AxoBits 39 for a priori corrections.  For details and how to get corrected article from the AxoBits 39 pdf down load click here.

Ionic Mobility Tables The tables in this listing give lists of the ionic mobilities stored in the Junction Potential Calculator programs, JPCalc and JPCalcW, together with more recent additional ionic values and references for further information.

N.B.   The above Mobility table went through a major update on October 23, 2003
 and further addition on October 29, 2003.

 

TEACHING

ArtMem for Windows (ArtMemW), converted from a DOS-based interactive graphical program ArtMem by PHB,  it was designed to simulate an experiment to illustrate how membrane potentials are set up across an ion-selective artificial membrane and would be a good first introduction to membrane potentials, prior to using the MemPotW or MEMPOT program. Further details are also given in an accompanying screen.

MemPot for Windows (MemPotW) converted from a DOS-based interactive graphical program MemPot by PHB, it was designed as an interactive teaching program that simulates the measurement of membrane potentials on excitable cells and with the aim of showing students how resting membrane potentials and action potential peaks depend on [K] and [Na] concentrations and on their relative permeabilities. Further details are also given in an accompanying screen.

MemCable for Windows (MemCableW) , converted from a DOS-based interactive graphical program MemCable by PHB, it was designed to simulate a microelectrode experiment which illustrated the passive time-dependent properties of a spherical neuron and the cable properties of a nerve and muscle fibre. Further details are also given in an accompanying screen.
