Study Arms (4)

Traumatic Brain Injury (TBI)

EXPERIMENTAL

Individuals with moderate-to-severe injury severity, defined as post-traumatic amnesia lasting more than 24hrs, loss of consciousness lasting more than 30 min, Glasgow Coma Scale (GCS) score less than 13.

Behavioral: Learning through feedback

Traumatic Brain Injury (TBI) with MDD

EXPERIMENTAL

Individuals with moderate-to-severe injury severity, defined as post-traumatic amnesia lasting more than 24hrs, loss of consciousness lasting more than 30 min, Glasgow Coma Scale (GCS) score less than 13. In addition, individuals will have a diagnosis of major depressive disorder (MDD) as per DSM-5.

Behavioral: Learning through feedback

Major Depressive Disorder (MDD)

EXPERIMENTAL

Individuals meeting criteria for major depressive disorder (MDD) including qualifiers 'in partial remission' or 'in full remission' if they are actively in treatment for the condition and still carry the depression diagnosis.

Behavioral: Learning through feedback

Healthy Individuals

EXPERIMENTAL

Healthy individuals without psychiatric and neurological conditions.

Behavioral: Learning through feedback

Interventions

The goal of this investigation is to examine the influence of feedback timing on learning and brain function.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • I am between the ages of 18 and 65.
  • I have been diagnosed with a TBI.
  • I am an individual without TBI.
  • I am right-handed.
  • I have normal vision or corrected to normal vision.
  • I can read and speak English fluently.
  • I do or do not have a current diagnosis of Depression.
  • I am not currently pregnant.

You may not qualify if:

  • I have had a neurological disease, other than TBI.
  • I have a significant history of alcohol or drug abuse as determined by study staff.
  • I have metal in my body (shrapnel, piercing that cannot be taken off, retainer on the upper jaw).
  • I have something in my body that restricts me from having an MRI such as: an aneurysm clip; implanted neural stimulator; implanted cardiac pacemaker or auto-defibrillator; cochlear implant (internal hearing aids); ocular foreign body (e.g. metal shavings in my eye), insulin pump or any pre- existing eye conditions (such as blurry vision, seeing double, and abnormal eye movements).
  • I experience discomfort in closed spaces (claustrophobia).
  • I have been diagnosed with a neurologic illness such as epilepsy, brain tumors, etc. (e.g. schizophrenia and bipolar disorder).
  • I have had corticosteroid treatment less than a month ago as determined by study staff review of my medications.
  • I have been informed by my doctor that is it unsafe for me to receive regular MRI as part of my medical care.
