INTRODUCTION The fruit fly Drosophila melanogaster has been instrumental in expanding our understanding of early aspects of neural development. The use of this model system has greatly added to our knowledge of neural cell-fate determination, axon guidance, and synapse formation. It has also become possible to access and make electrophysiological recordings directly from neurons in situ in an intact central nervous system (CNS), which has facilitated studies of the development and regulation of neuronal signaling. It is possible to obtain electrophysiological recordings from all stages of Drosophila. Exposure of the intact Drosophila CNS is a prerequisite for such electrophysiological recordings. The dissection procedure described here can be applied to both late-stage embryos (stage 16 onward) and larvae. Because of their size, third-instar larvae are more difficult to flatten using this method and, if recording from this stage, the reader might consider using insect pins for the dissection or isolating the CNS using an alternative method. The dissection should take <10 min if all preparation work has been completed in advance. Owing to the short life span of the dissected larva, it is not recommended that the procedure be stopped or the preparation stored for later use.

Drosophila melanogaster is a powerful experimental model system for studying the function of the nervous system. Gene mutations that cause dysfunction of the nervous system often produce viable larvae...

Laparoscopic cholecytectomy can be by starting the dissection at the triangle of calots or as a fundus first dissection. Dissection can be with electrocutery or ultrasonic. The optimal te...
Glycosylated proteins which are part of the salivary glue that Drosophila larvae secrete as a means of fixing themselves to an external substrate for the duration of the pre-pupal and pupal period.
Dissection in the neck to remove all disease tissues including cervical LYMPH NODES and to leave an adequate margin of normal tissue. This type of surgery is usually used in tumors or cervical metastases in the head and neck. The prototype of neck dissection is the radical neck dissection described by Crile in 1906.
Proteins that originate from insect species belonging to the genus DROSOPHILA. The proteins from the most intensely studied species of Drosophila, DROSOPHILA MELANOGASTER, are the subject of much interest in the area of MORPHOGENESIS and development.
A guanine nucleotide exchange factor from DROSOPHILA. Sevenless refers to genetic mutations in DROSOPHILA that cause loss of the R7 photoreceptor which is required to see UV light.
Recording of regional electrophysiological information by analysis of surface potentials to give a complete picture of the effects of the currents from the heart on the body surface. It has been applied to the diagnosis of old inferior myocardial infarction, localization of the bypass pathway in Wolff-Parkinson-White syndrome, recognition of ventricular hypertrophy, estimation of the size of a myocardial infarct, and the effects of different interventions designed to reduce infarct size. The limiting factor at present is the complexity of the recording and analysis, which requires 100 or more electrodes, sophisticated instrumentation, and dedicated personnel.
