We describe an amplifier design in the following paper:
Land, B.R., Wyttenbach, R.A., and Johnson, B.R. (2001). Tools for physiology labs: An inexpensive high-performance amplifier and electrode for extracellular recording. J. Neurosci. Meth.106:47-55.
Download pdf files of the printed circuit board (20 kB) and a preprint (192 kB) of the above paper. A list of parts with sources and approximate prices can be found here. For details of constructing the suction electrode, see Appendix E above.
If you want to make printed circuit boards commercially, you can download a template here (15 kB). Use this file with Windows software from ExpressPCB.com and have them make your PC boards. Each board contains two amplifier circuits and fits ExpressPCB's inexpensive "miniboard" format. If you use this design, note that the standoffs are 2.125 inches apart, not 2.5 inches apart as shown in the paper. Thanks to John Kauer of Tufts for putting the circuit in pcb format.
Stimulator and SIU
We describe circuitry for a stimulator and stimulus isolation unit in the following paper:
Land BR, Johnson BR, Wyttenbach RA, and Hoy RR (2004) Tools for physiology labs: Inexpensive equipment for physiological stimulation. J. Undergrad. Neurosci. Ed. 3(1):A30-A35.
