✦ Synopsis

A new temperature-sensitive paralytic locus on the X chromosome of Drosophila melanogaster called torpid is described. Mosaic analysis shows that the focus of defect in torp lies in the presumptive neural region of the blastoderm. Electrophysiological tests indicate that the excitability of the cervical axons is lowered at elevated temperatures.

Temperature-sensitive paralytic mutations have attracted attention because of the possibility that some of these might affect elementary functions of nerves or muscles. Several X-linked and autosomal paralytic genes have been identified and the neurophysiological correlates of paralysis in these mutants have been described (
