Unsuitability of Glycylglycine, Phosphate and Tris-(hydroxymethyl) aminomethane Buffer Solutions for the Field Potentials of Guinea Pig Olfactory Cortical Slice

Abstract

The saline solutions buffered with glycylglycine, tris (hydroxymethyl) aminomethane and phosphate were not suitable for recording the evoked potentials from the olfactory cortical slices of guinea pigs, because these potentials were suppressed in amplitude by superfusion with these buffer solutions.
