<< A general principle of sensory systems is that they adapt to prolonged stimulation by reducing their response over time. >>
<< as opposed to most sensory and visual neurons, and in particular to the motion vision sensitive neurons in the brains of both flies and mammals, the descending neurons show little adaption during stimulus motion. (..) the optic-flow-sensitive descending neurons display persistent firing, or an after-effect, following the cessation of visual stimulation, consistent with the lingering calcium signal hypothesis. >>
AA results << show a combination of adaptation and persistent firing in the neurons that project to the thoracic ganglia and thereby control behavioral output. >>
