Description of Study:

In this study, you will perform basic cognitive and motivational tasks (eg., responding to visual stimuli) on a computer after being presented with transcranial magnetic stimulation (TMS), a form of non-invasive brain stimulation that involves the delivery of brief magnetic pulses to stimulate neurons in the cortex and transiently disrupt neural activity in a small area of the brain. This study consists of two sessions total which take approximately 2 hours each and are separated by at least 24 hours. Participants are compensated $12.50 an hour for your participation, with an additional $5 for every 20 minutes if the session where to go longer than 2 hrs.

Will participants be compensated for participation?

14. Are suffering from sleep deprivation (lesser than 4 hours of sleep in the past 24hrs).
15. Currently consume any of the drugs and/or medicines listed below that are Drug Contraindications, or any drugs and/or medicine known to lower the seizure threshold.

Drug Contraindications include: Alcohol (within one hour of testing), Amitriptyline, Amphetamines, Chlorpromazine, Clozapine, Cocaine, Doxepin, Foscarnet, Gamma-hydroxybutyrate (GHB), Ganciclovir, Imipramine, Ketamine, Maprotiline, MDMA (ecstasy), Nortriptyline, Phencyclidine (PCP), Ritonavir, Theophylline, or any other medication prescribed for antidepressant medication or medication prescribed to decrease seizure thresholds.
