title: Printed circuit microelectrodes and their application to honeybee brain.
abstract: The application of printed circuit technology to the production of a new type of multi-channel microelectrode is described. 2. Recordings have been obtained from the the protocerebrum of the honeybee Apis mellifera L. using printed circuit microelectrodes in both restrained and free-moving preparations. 3. These recordings are compared with those previously obtained from conventional probe microelectrodes and are found to have similar characteristics of transient voltage changes superimposed on an undifferentiated high frequency background. 4. A wide range of development possibilities for the printed circuit microelectrode are discussed.
