Effect of individualised transcranial magnetic stimulation (TMS) on cognitive functioning in healthy volunteers

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.
