Title

Diamond electrodes for neurodynamic studies in Aplysia californica

Abstract

Abstract

As part of an ongoing effort to demonstrate that diamond is a versatile electrode material for biological applications, we present our progress in the development of diamond electrodes for the study of neurodynamics in an animal model, Aplysia californica. Diamond provides a unique opportunity to integrate neural stimulation and sensing in the same implantable device. Data from several parallel studies are presented: in vitro measurement of serotonin concentration, measurement of electrical activity, and neural stimulation. Using diamond microelectrodes, changes of the Aplysia californica's feeding patterns are being studied as a function of concentration of serotonin, which can act as a neuromodulator of feeding behavior.
