Экспериментальный: ACC Real Time fMRI Feedback
Each participant will undergo thermal pain threshold assessments ten times using the Medoc Pathway System with MRI-compatible ATS Thermode (30mmX30mm; Medoc Inc, Israel). Participants will be instructed to "focus on the thermal stimuli" for the first 5 trials, and to engage in three cognitive pain inhibition strategies (Attention/Distraction Strategy, Stimulus Quality/Severity Strategy, and the Control Strategy. The participants will be randomly assigned to receive Real Time fMRI Feedback of inverse activation in the rACC after each pain/rest block during the last 3 fMRI scans in the form of two simple thermometer images on the in-scanner computer display. |
One of three Cognitive Pain Inhibition Strategies.
The Participant will be instructed to attend away from the thermal stimulus (for example, to the other side of the body).
Vividly imagine they are somewhere else, or engage in a high-demanding mental task such as counting backward by 7's or completing math problems to distract from the experience
One of three Cognitive Pain Inhibition Strategies.
The Participant will be instructed to attempt to perceive the stimulus as a neutral sensory experience rather than pain.
Attempt to perceive the stimulus as low intensity rather than high intensity.
One of three Cognitive Pain Inhibition Strategies.
The Participant will be instructed to attempt to take control of their perception of the painful experience.

Экспериментальный: PFC Real Time fMRI Feedback
Each participant will undergo thermal pain threshold assessments ten times using the Medoc Pathway System with MRI-compatible ATS Thermode (30mmX30mm; Medoc Inc, Israel).
Participants will be instructed to "focus on the thermal stimuli" for the first 5 trials, and to engage in three cognitive pain inhibition strategies (Attention/Distraction Strategy, Stimulus Quality/Severity Strategy, and the Control Strategy.
The participants will be randomly assigned to receive Real Time fMRI Feedback of inverse activation in the PFC after each pain/rest block during the last 3 fMRI scans in the form of two simple thermometer images on the in-scanner computer display.

Average Unpleasantness
Временное ограничение: Before and After fMRI Paradigm, an average of 2 hours
|
All participants will undergo thermal pain threshold testing directly before (Baseline) and after MRI. Participants will be asked to rate pain unpleasantness, on a scale of 0-10, before the fMRI Paradigm (Baseline) and directly after the fMRI paradigm (after MRI). 0="no unpleasantness" and 10="worst unpleasantness imaginable" |

Average Pain Rating
Временное ограничение: Before and After fMRI Paradigm, an average of 2 hours
|
All participants will undergo thermal pain threshold testing directly before (Baseline) and after MRI scan.Participants will be asked to rate painfulness of the thermal stimuli applied, on a scale of 0-10, before the fMRI Paradigm (Baseline) and directly after the fMRI paradigm (after MRI).
0="no pain" and 10="worst pain imaginable"

Ability to Distract
Временное ограничение: Before and After fMRI Paradigm, an average of 2 hours
|
All participants will undergo thermal pain threshold testing before and after fMRI paradigm.
Participants will rate the ability to distract themselves from the thermal stimuli, on a scale of 0-10, before fMRI paradigm (Baseline) and after fMRI paradigm, 0="not able to distract at all" and 10="completely able to distract".
A Higher rating represents greater ability to distract from thermal pain stimuli.
