Behavioral response and transmitter release during atonia elicited by medial medullary stimulation.

abstract：:In this study, the juxtamembrane region of the Drosophila SNARE protein neuronal-Synaptobrevin (n-Syb) was tested for its role in synaptic transmission. A transgenic approach was used to express n-Syb mutant genes. The transgenes carried engineered point mutations that alter the amino acid sequence of the conserved tr...
