Brief Summary
Aim: Investigate whether transcranial photobiomodulation (tPBM) using near-infrared light exposure to the head, can improve frontal lobe executive function, working memory and overall mood in normal volunteer participants. Hypothesis: The investigators predict that tPBM will increase cognitive functioning, as measured by Cambridge Cognition cognitive testing in study subjects.

Outcome Measures
Primary Outcomes (6)
ERT: Emotional Recognition Task
The median latency from stimulus onset to the subject's response button touch (i.e. emotion chosen) for all problems during assessment blocks.
16 weeks
PAL: Paired Associates Learning
The number of times the subject chose the incorrect box for a stimulus on assessment problems, plus an adjustment for the estimated number of errors they would have made on any problems, attempts and recalls they did not reach
16 weeks
RTI: Reaction Time
The mean duration between the onset of the stimulus and the release of the button. Calculated for correct, assessed trials where the stimulus could appear in any one of five locations.
16 weeks
RVP: Rapid Visual Information Processing
A' (A prime) is the signal detection measure of sensitivity to the target, regardless of response tendency (the expected range is 0.00 to 1.00; bad to good). In essence, this metric is a measure of how good the subject is at detecting target sequences.
16 weeks
SST: Stop Signal Task
The estimate of the length of time between the go stimulus and the stop stimulus at which the subject is able to successfully inhibit their response on 50% of the trials.
16 weeks
SWM: Spatial Working Memory
Between errors are defined as times the subject revisits a box in which a token has previously been found. This is calculated for trials of four, six and eight tokens.
16 weeks
Study Arms (2)
NIR brain stimulation
EXPERIMENTALAn Omnilux device will be used to put NIR light on the head and forehead of the subject age 18-25 or 65-85. The device is a low risk device as determined by the IRB. Thirty (30) subjects will receive this light at 6 visits over 16 weeks. An automated interactive software self-test will be used at baseline and at three subsequent visits to quantify subject cognitive functions.
Sham
SHAM COMPARATORAn Omnilux Device will be used at a safe wavelength not associated with photobiomodulation, putting sham light on the head and forehead of the subject age 18-25 or 65-85. The device is a low risk device as determined by the IRB. Thirty (30) subjects will receive this light at 6 visits over 16 weeks. An automated interactive software self-test will be used at baseline and at three subsequent visits to quantify subject cognitive functions.
Interventions
The Omnilux LED array sources can be changed to emit different wavelength.
Eligibility Criteria
You may qualify if:
- Age: 18-25 or 65-85
- Women of child-bearing potential, must use a double-barrier method for birth control (e.g. condoms with spermicide) if sexually active during the study and for 30 days post treatment of any kind.
- Subject Informed Consent obtained in writing in compliance with local regulations prior to enrollment into this study.
- The subject (and caregiver, if applicable) is willing to participate in this study for at least 12 weeks.
You may not qualify if:
- Inability to speak or read English (necessary for cognitive testing software use).

- Diagnosed with a neurodevelopmental condition (autism or ADHD)
- A traumatic event that resulted in PTSD
- Any unstable medical illness (defined as any medical illness which has not been well-controlled with standard-of-care medications)
- A significant skin condition (i.e., hemangioma, scleroderma, rash, open wound) or medical implant (e.g. metal plate, implantable shunt or valve) on the head.
- Inability to understand or participate in the consent and performance of the study.
- Those with Parkinson's Disease, End Stage Renal Disease, and/or End Stage Liver Disease
