“…Indeed, therapeutic interventions at the level of brain circuitry might become feasible in the near future. Promising upcoming techniques such as online neuro-feedback (Hammond, 2005; Scheinost et al, 2013; Simkin, Thatcher, and Lubar, 2014; Stoeckel et al, 2014; Yuan et al, 2014), transcranial magnetic brain stimulation (Paes et al, 2011; Pigot et al, 2008; Zwanzger et al, 2009), or behavioral interventions might be developed to strengthen frontal-striatal networks in anxiety disorders.…”
Anxiety disorders are among the most common psychiatric disorders of adolescence. Behavioral and task-based imaging studies implicate altered reward system function, including striatal dysfunction, in adolescent anxiety. However, no study has yet examined alterations of the striatal intrinsic functional connectivity in adolescent anxiety disorders.
The current study examines striatal intrinsic functional connectivity (iFC), using six bilateral striatal seeds, among 35 adolescents with anxiety disorders and 36 healthy comparisons.
Anxiety is associated with abnormally low iFC within the striatum (e.g., between nucleus accumbens and caudate nucleus), and between the striatum and prefrontal regions, including subgenual anterior cingulate cortex, posterior insula and supplementary motor area.
The current findings extend prior behavioral and task-based imaging research, and provide novel data implicating decreased striatal iFC in adolescent anxiety. Alterations of striatal neurocircuitry identified in this study may contribute to the perturbations in the processing of motivational, emotional, interoceptive, and motor information seen in pediatric anxiety disorders. This pattern of the striatal iFC perturbations can guide future research on specific mechanisms underlying anxiety.

“…The number of sessions of NF in our study has yielded large positive effects in earlier controlled studies performed in children with ADHD [38]. We cannot rule out that PBTS would benefit from a more intensive training, however, in children and adults with traumatic brain injury, whose brain damage is of structural nature as in PBTS, similar numbers of sessions produced positive outcomes [40]. It could be argued that using automatically adjusted thresholds is less effective than manually adjusted, however, a recent study did not find larger effect sizes when thresholds were switched from automatically to manually adjusted [35].…”
“…Neurofeedback can enhance the function of neuronal networks associated with mood and behavior (Simkin, Thatcher, & Lubar, 2014), and lead to alterations in brain structure that are observable via magnetic resonance imaging (MRI; Ghaziri et al, 2013). Ghaziri et al performed MRI on participants before and after a course of treatment with NFB, which indicated that parts of the frontal lobe and association cortical areas increased in size.…”
Introduction.Neurofeedback (NFB) and heart rate variability (HRV) training present promising, nonpharmaceutical intervention strategies for anxiety and depression. This report is the first to address whether concurrent NFB and HRV (NFB+HRV) provides a viable intervention for symptoms of anxiety and depression, measured by the Achenbach System of Empirically Based Assessment (ASEBA) questionnaire. Methods. 183 children and adults with symptoms of anxiety and/or depression underwent NFB+HRV training. Psychological symptom rating, EEG, blood pressure, breathing pattern, and HRV were measured before and after treatment. Results. After NFB+HRV training, symptoms of anxiety (p < .001, d z = 1.42) and depression (p < .001, d z = 1.34) were reduced in children and adults. The majority of individuals with pretreatment symptoms of anxiety (82.8%) or depression (81.1%) experienced ASEBA improvements of clinical importance. There were also significant changes in EEG, breathing rate, and HRV. For the 16 individuals copresenting with hypertension, systolic and diastolic blood pressure were significantly reduced. Conclusion. We present evidence that NFB+HRV training may provide an effective, nonpharmaceutical intervention to reduce symptoms of anxiety and depression in children and adults. Additionally, NFB+HRV training may improve EEG, blood pressure, resting breathing rate, and HRV.
