Abstract

A novel mechanical method, for studying acutely isolated maturing Drosophila central neurons, has been developed. Electrophysiological experiments have been carried out to assess the quality of these acutely dissociated neurons. The mechanically dissociated Drosophila central neurons were divided into three categories depending on their size and morphological features. Four types of whole-cell K + currents were identified in these neurons, based on their kinetic properties. Moreover, the K + currents in the new preparation were found to have similar electrophysiological and pharmacological properties to those reported in the cultured neurons. The new technique, however, was more rapid and convenient. Furthermore, this new system was successfully applied to the isolation of neurons from the adult Drosophila, a process that is extremely difficult by routinely used methods. Thus, this new preparation would be very reliable and applicable to preparing Drosophila central neurons for biophysical and physiological studies.
