“…This allows for detection of the neural mechanisms underlying the intervention through real-time monitoring during the intervention. This method is particularly suitable with NIRS and has been used in various forms of psychotherapy (Tables 1, 2), such as during mindfulness meditation (Gundel et al, 2018;Rosenbaum et al, 2020a), interpersonal brain synchronization between the counselor and client (Zhang et al, 2018(Zhang et al, , 2020, attention training with metacognitive therapy (Rosenbaum et al, 2018), exposure to stimuli for specific phobia (Landowska et al, 2018;Rosenbaum et al, 2020b), role lettering in writing therapy (Okamoto et al, 2010), and trauma-related recall with eye movement desensitization (Ohtani et al, 2009;Amano and Toichi, 2016). Nevertheless, this method restricts body movement during the intervention, which could disrupt performance, depending on the type of psychotherapy.…”

“…It has been suggested that this is because these individuals must exert significant effort to inhibit excessive emotion. In such cases, deactivation of the LPFC region is an index for improvement (Ohtani et al, 2009;Okamoto et al, 2010;Amano and Toichi, 2016;Glassman et al, 2016;Ong et al, 2020;Rosenbaum et al, 2020a,b; Table 2). Implementation of exposure therapy reduced the LPFC activity while watching videos of spiders in patients with arachnophobia (Rosenbaum et al, 2020b; Tables 1, 2).…”

This perspective article discusses the importance of evidence-based psychotherapy and highlights the usefulness of near-infrared spectroscopy (NIRS) in assessing the effects of psychotherapeutic interventions as a future direction of clinical psychology. NIRS is a safe and non-invasive neuroimaging technique that can be implemented in a clinical setting to measure brain activity via a simple procedure. This article discusses the possible benefits and challenges of applying NIRS for this purpose, and the available methodology based on previous studies that used NIRS to evaluate psychotherapeutic effects. Furthermore, this perspective article suggests alternative methodologies that may be useful, namely, the single- and multi-session evaluations using immediate pre- and post-intervention measurements. These methods can be used to evaluate state changes in brain activity, which can be derived from a single session of psychotherapeutic interventions. This article provides a conceptual schema important in actualizing NIRS application for evidence-base psychotherapy.

“…Data analyses were based on effect size (mean rest oxy-Hb − mean task oxy-Hb/standard deviation [SD] of rest oxy-Hb). Oxygen consumption has various effects on cerebral blood flow, cerebral blood volume, and the metabolic rate during cortical activity 20 ) . Based on the oxy-Hb values, we determined the cortical areas that were responsive to our task 21 ) .…”

Effect of anticipation triggered by a prior dyspnea experience on brain activity

et al. 2015

[Purpose] Oxygenated hemoglobin (oxy-Hb) concentrations in the prefrontal cortex are closely associated with dyspnea. Dyspnea is influenced not only by physical activity, but also by visual stimuli, and several studies suggest that oxy-Hb concentrations change in response to certain external stimuli. However, the effects of internal psychological states on dyspnea have not been reported. This study explored the influence of anticipation triggered by previous episodes of dyspnea on brain activity. [Subjects] The subjects were 15 healthy volunteers with a mean age of 25.0 ± 3.0 years. [Methods] The subjects were shown a variety of photographs and instructed to expect breathing resistance matched to the affective nature of the particular photograph. After viewing the images, varying intensities of breathing resistance that were identical to, easier than, or harder than those shown in the images were randomly administered to the subjects; in fact, the image and resistance were identical 33% of the time and discordant 66% of the time. [Results] The concentrations of oxy-Hb in the right medial prefrontal cortex (rMPFC) increased significantly with an inspiratory pressure that was 30% of the maximum intensity in the subjects shown a pleasant image compared to the concentrations in subjects shown an unpleasant image. Moreover, rMPFC activity was significantly correlated with the magnitude of the dyspnea experienced. [Conclusion] These results suggest that a correlation exists between increased oxy-Hb in the rMPFC and the effects of expectations on dyspnea.
