FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
The latency of the responses of the tergotrochanteral muscle (TTM) and the tibial levator muscle (TLM) following brain stimulation is longer than in wild-type flies, although the interval between the TTM and TLM responses appears normal.
