COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A first experimental session will be conducted to determine the 'optimal' and 'suboptimal' sites for transcranial magnetic stimulation (TMS) using a cognitive task. TMS involves the administration of strong, high frequency magnetic pulses to the brain. Participants will be required to complete a cognitive task while receiving TMS to different stimulation sites. The 'optimal' site is that where the largest effect of TMS on performance occurs, and the 'suboptimal' site is that where the smallest effect of TMS occurs. The duration of this session is approximately 1 hr. This session will occur approximately 1 week prior to the first intervention session.

Arm 1: TMS administered by a university student to an optimised, individualised stimulation site for approximately 3 min at the Black Dog Institute. TMS will involve the administration of strong, high frequency magnetic pulses to the brain.

Arm 2: TMS administered by a university student to a suboptimal, individualised stimulation site for approximately 3 min at the Black Dog Institute. TMS will involve the administration of strong, high frequency magnetic pulses to the brain.

Arm 1 and Arm 2 will be conducted at least 2 days apart.
