    Ottmar V Lipp
    School of Psychology, The University of Queensland, QLD 4072, Australia
    Neurosci Lett 427:94-8. 2007
    ..This finding suggests that the blink reflex facilitation observed at a SOA of 0 ms with the onset of a go signal reflects on the summation of sub- and supra-threshold activations of the startle pathway...

    Sarah J Forbes
    University of Queensland, Brisbane, Queensland, Australia
    Cogn Emot 25:794-804. 2011

    School of Psychology, University of Queensland, Queensland, 4072, Australia
    Psychophysiology 45:1068-78. 2008
