... The financial hardship experienced by health service psychologists with high student loan debt calls into question training requirements that may exacerbate economic strain, including doctoral internship (Gee et al., 2022;Palitsky et al., 2022). Internship is a year-long capstone training requirement for health service psychology doctoral students, in which trainees provide full-time supervised clinical services, typically at a site external to their graduate institutions. ...

... Clinicians have forcibly struggled to identify best practices that incorporate the needs of the patient, trainee, supervisor, unit, and healthcare system, the balance of which has been quite delicate. This pandemic has also had a profound impact on the structure of clinical training and provision of supervision across medical settings (Palitsky, Kaplan, Brodt, Anderson, Athey et al., 2021). While there continues to be a growing body of literature supporting the use of virtual technology in mental health care (Langarizadeh et al., 2017), there is little written about the role of telesupervision. ...

... Proof-of-concept studies of deep brain stimulation with ultrasound to modulate mood have been reported [10][11][12], but the studies have shown limited effectiveness and effect duration. Two reasons might underlie those results: (1) limited ultrasound intensities delivered into the brain due to the strongly attenuating skull [13,14] and (2) lack of magnetic resonance imaging (MRI) guidance for precision targeting of specific deep brain targets. ...

... Due to a rather scarce literature, it remains unclear whether the aforementioned neural correlates might be a concomitant feature of symptoms of depression, or whether trait or state rumination might (also) account for this characteristic neural activation pattern. As ruminative thinking is assumed to be a transdiagnostic factor and part of the psychopathological abnormalities in various disorders [5][6][7][8][9] , this might have crucial implications for a more coherent model of neural pathways assumed to be involved in these disorders and consequently also in the respective treatment. ...

... Electroencephalography (EEG) recording is a noninvasive quantitative diagnostic tool for detecting rhythmic electrophysiological activity of neuron clusters in the cerebral cortex, and its signals can reflect moodrelated physiological and pathological changes with the advantages of high temporal resolution and convenience [6,7]. It has been found that there is a specificity in the EEG signals of people with depressive symptoms, such as low δ power during sleep [8,9] and high β power during wakefulness [10][11][12], lateralization of left and right brain regions in θ and α waves [13][14][15] and asymmetry in power values of the high (β) and low (δ, θ) frequency bands [16]. Measuring depressive symptoms objectively and searching for EEG biomarkers in people with depressive symptoms has been one of the focuses of researchers [17][18][19]. ...

... One study prevented participants from acting by exposing them to uncontrollable (vs. controllable) aversive noise blasts and found that PFTA decreased in response to the uncontrollable noise blasts (Reznik et al., 2017). Finally, both PFTA and approach motivation are linked to mesolimbic dopamine (Wacker et al., 2006(Wacker et al., , 2013Wacker & Smillie, 2015). ...

... To demonstrate the regional specificity of our results, we further analyzed the 12-15 Hz band in the frontal (Fz and FCz), central (Cz and CPz), and parietal (Pz) regions. To increase the contribution of local electrical activities and reduce the effect of distal volume-conducted sources, 41,42 the EEG data were transformed using a spherical spline surface Laplacian algorithm 43 via the current source density (CSD) toolbox function 44 (smoothing constant lambda = 10 −5 ; spherical spline order = 4). The statistical analyses were identical to those used in the main analysis of SMR power. ...

... But watching negative videos did not differ from other conditions. In general, the left hemisphere has been considered to support positive emotions (Allen and Reznik 2015). Thus, lowered left frontal activity was found in depressive subjects (Beeney et al. 2014) and while watching sad movies (Killeen and Teti 2012). ...
