Persons having a history of mild TBI (mTBI) will not be excluded.

• Current or previous long-term immune suppressive therapy. Systemic steroid use, even short-term, must not have been used within the month prior to enrollment
• Any medical condition that would make the study procedures risky for the participant (e.g. congestive heart failure, coronary artery disease, chronic obstructive pulmonary disease, severe osteoarthritis, exercise-induced angina and poorly controlled asthma).
• Active participation in a clinical protocol (e.g. anti-inflammatory drug intervention study) which includes an intervention that may affect the results of the current study.
• Inability to perform the bicycling exercise task. (e.g. coronary artery disease, not having a lower limb, disabling stroke)
• Not willing to allow for research data and samples to be shared broadly with other researchers.
• Symptom severity that makes it impossible for the volunteer to travel to NIH for extended inpatient evaluation
• Use of medications with a high-risk for withdrawal-related complications (i.e. long-acting opiates or benzodiazepines).

Additional Exclusion criteria for participants undergoing TMS:

- Pacemaker, implanted pump, stimulator, cochlear implant or metal objects inside the eye or skull.

Participants with unconfirmed metal may have further evaluation to rule out metal in the eye or skull.

Participants without metal after evaluation may proceed to TMS.

- A personal history of seizure disorder

Additional Exclusion criteria for participants undergoing MRI:

- Metal in the body which would make having an MRI scan unsafe, such as pacemakers, stimulators, pumps, aneurysm clips, metallic prostheses, artificial heart valves, cochlear implants or shrapnel fragments, or having a history of being a welder or metal worker, since small metal fragments may be in the eye. Participants with unconfirmed metal may have further evaluation to rule out metal in the eye

or skull. Participants without metal after evaluation may proceed to MRI.

• Substantial claustrophobia
• Inability to lie on back for up to 2 hours

Additional Exclusion criteria for Healthy Veteran Controls:
