However, the specific contribution of each sensory system during attentional processing and, importantly, how these interact with the required behavioural motor goals remains unclear. Experiments will be presented that used EEG and event-related potentials (ERPs) to test hypotheses that activity from modality-specific somatosensory cortical regions would be enhanced with task-relevant bimodal (visual-tactile) stimuli and suppressed when the same stimuli were in conflict for the behavioural task. Results show that specific modality-specific somatosensory ERPs are modulated with attentional state (either enhanced or suppressed) and this is related to the behavioural impacts when presented in conflict. Transient inhibition of the dorsolateral prefrontal cortex using transcranial magnetic stimulation reduces these attention-based modulations of tactile ERPs. The functional significance of this to sensorimotor behavior will be discussed.</div><div><br><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Feb 23, 2017 at 7:48 AM, Bryan Tripp <span dir="ltr"><<a href="mailto:bptripp@gmail.com" target="_blank">bptripp@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Hi everyone, </div><div><br></div><div>Please join us for the next CTN seminar, Tuesday of next week (Feb 28) at 3:30 in PAS 2464.
