About this study
Deficits in emotional cognitive control are present in a number of clinical psychiatric populations including depression, anxiety, and PTSD. Deficits in this domain of function limit one's ability to focus attention on goal directed activities while inhibiting reactions to irrelevant emotional stimuli, and this contributes to the symptoms of these disorders and makes individuals less likely to be successful in existing treatments. The left dorsolateral prefrontal cortex (LDLPFC) and its connectivity with other regions (i.e., dorsal anterior cingulate cortex, ventromedial prefrontal cortex, insula, amygdala) is thought to play a central role in facilitating emotional cognitive control. However, past research has primarily utilized correlational approaches that limit conclusions about the directionality of these relationships. Enhancing our understanding of the neural underpinnings of emotional cognitive control could be valuable for informing treatment for populations with deficits in these processes.
The current study utilizes a neuromodulatory approach called real-time functional magnetic resonance imaging neurofeedback (rtfMRI-nf) whereby participants observe their own neural activity in the moment and are taught to self-regulate this activity. Healthy adult participants will be trained to increase neural activity in LDLPFC while involved in mental tasks involving emotional cognitive control processes. The mental tasks will include counting, remembering words, or planning events while viewing negatively-valenced emotional words (e.g., kill, death, threat). This study will use an experimental approach with participants being randomized to either LDLPFC rtfMRI-nf or control rtfMRI-nf where participants receive neural feedback from a region not involved with emotional cognitive control processes. Resting-state fMRI scans and behavioral testing sessions will take place before and after rtfMRI-nf.

The specific aims are to examine the impact of LDLPFC rtfMRI-nf on: (1) LDLPFC activity during emotional cognitive control and (2) LDLPFC functional connectivity with other brain regions during rest. Additionally, this study will examine the neural correlates of emotional cognitive control independent of rtfMRI-nf. Thus, the final specific aim is to (3) Investigate relationships between individual differences in LDLPFC engagement, cognitive control performance, trauma history, and sleep quality. To facilitate the relevance of these findings to clinical populations, trauma exposure and sleep quality will be explored as moderators of neural change across time for those in the rtfMRI-nf group.
To these ends, this study will use rtfMRI-nf to experimentally investigate the relationship between LDLPFC activity and emotional cognitive control as well as investigate these neural mechanisms independent of rtfMRI-nf. This research will improve our understanding of emotional cognitive control and demonstrate whether this is a modifiable target for intervention in populations with deficits in this domain of function.

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Left dorsolateral prefrontal cortex activity during emotional cognitive control (pre- to post-neurofeedback) (time frame: Approximately 2 hours after baseline assessment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Aug 2022.
