The Impact of a Startling Acoustic Stimulus and Transcranial Magnetic Stimulation on Reaction Times in Unimpaired Older Adults
An unexpected loud noise known as a Startling Acoustic Stimulus (SAS) can cause a startle reflex response, which has been shown to enhance movement in stroke patients [1, 2, 3]. The use of Transcranial Magnetic Stimulation along with an SAS results in a significant delay in the onset of SAS-released movements [4, 5]. This leads to the issue of determining the characteristics of the startle reflex in movements that are governed by the reticulospinal tract (RST) and corticospinal tract (CST). Single-pulse TMS was used to stimulate the left hemisphere and participants were exposed to 5 loud startling acoustic stimuli of 120 dB at random intervals.
