Mechanical movement of the insect heart recorded with a continuous laser beam


Play all audios:

ABSTRACT WE describe here a technique—using a laser—for measuring the contractile excursions of the insect heart after the insect (in this case _Sarcophaga bullata_) has been immobilized in


wax, and sections of the dorsal abdominal wall removed. The laser technique makes it possible to record mechanical movement from a selected area of tissue without interfering with a


capillary microelectrode which records bioelectric events from a single cell. Access through your institution Buy or subscribe This is a preview of subscription content, access via your
