Effects of L-glutamate on 1F Helix aspersa neurons

摘要

The aim of this work is to characterize the effect of L-glut and related compounds on the electrical properties of 1F identified neurons of the garden snail Helix aspersa. We used intracellular recording experiments with regular microelectrodes, in current clamp conditions. We report here that the putative L-glut receptor present in 1F Helix neurons has some similarities with the L-glut receptor present in vertebrates, regarding ionic permeability and biophysical properties. However, these responses show different pharmacological properties from those receptors found in vertebrates and mammals.
