PDF In order to be able to confidently assert that any RT speeding following a startling acoustic stimulus (SAS) is the result of activation in subcortical areas related to the startle reflex, a reliable indication that a startle reflex actually occurred is required. While the eye-blink response is typically used…
PDF This paper investigated whether an additive model of activation or a horse-race model would be a better fit for data showing that reaction times are facilitated to a greater degree than would be expected when a startling stimulus presented after the typical “go” signal. Abstract: When a startling acoustic…
Dr. Tony Carlsen was recently awarded an Early Researcher Award (ERA) from the Government of Ontario Ministry of Research and Innovation. This grant is intended help prominent young researchers build exceptional research teams by providing funding to enable increased recruitment of students, research fellows, technicians and assistants. Dr. Carlsen’s research project, entitled…
PDF This study investigated whether movements that were “imaged” or “imagined” to be executed involved a build up of preparatory activation in brain structures in a similar way as movements that were actually executed. By using a loud startling acoustic stimulus, we are able to elicit pre-planned movements if they…
PDF This study is a replication of a previous experiment that investigated how movement-related brain activation changes as a go-stimulus approaches in time. The previous experiment used a startle to show that activity increased in short time prior to the go-signal. However, startle activity was not reported, so this was only…
