The Brain

Acute ketamine administration has been widely used in neuroimaging research to mimic psychosis-like symptoms. Within the last two decades, ketamine has also emerged as a potent, fast-acting antidepressant. The delayed effects of the drug, observed 2–48 h after a single infusion, are associated with marked improvements in depressive symptoms. At the systems’ level, several studies have investigated the acute ketamine effects on brain activity and connectivity; however, several questions remain unanswered around the brain changes that accompany the drug’s antidepressant effects and how these changes relate to the brain areas that appear with altered function and connectivity in depression. This review aims to address some of these questions by focusing on resting-state brain connectivity. We summarise the studies that have examined connectivity changes in treatment-naïve, depressed individuals and those studies that have looked at the acute and delayed effects of ketamine in healthy and depressed volunteers. We conclude that brain areas that are important for emotional regulation and reward processing appear with altered connectivity in depression whereas the default mode network presents with increased connectivity in depressed individuals compared to healthy controls. This finding, however, is not as prominent as the literature often assumes. Acute ketamine administration causes an increase in brain connectivity in healthy volunteers. The delayed effects of ketamine on brain connectivity vary in direction and appear to be consistent with the drug normalising the changes observed in depression. The limited number of studies however, as well as the different approaches for resting-state connectivity analysis make it very difficult to draw firm conclusions and highlight the importance of data sharing and larger future studies.

University Athletes

University athletes are at high risk for both substance use and mental health problems. This study examined associations between substance use, mental health symptoms, and the resting state functional connectivity (rsFC) of key neural regions involved in self-monitoring and emotional regulation in a sample of female varsity athletes. 31 female university athletes completed measures of substance use, mental health symptoms, and underwent functional MRI scans during the pre-season. Athletes who were substance users had higher symptoms of depression than non-users (p = 0.04; Hedge’s g = 0.81). RsFC differences were observed between users and non-users in orbital frontal cortex (OFC) and bilateral hippocampal seeds, and negative associations between depression symptoms and rsFC in the left hippocampus and posterior cingulate cortex were observed in cannabis users. In female athletes, substance use is associated with greater self-reported depression symptoms and altered rsFC in self-monitoring and emotional regulation regions of the brain.

Abstract Background To determine whether depressive symptoms in traumatic brain injury (TBI) patients were associated with altered resting-state functional connectivity (rs-fc) or voxel-based morphology in brain regions involved in emotional regulation and associated with depression. Methods In the present study, we examined 79 patients (57 males; age range = 17–70 years, M ± s.d. = 38 ± 16.13; BDI-II, M ± s.d. = 9.84 ± 8.67) with TBI. We used structural MRI and resting-state fMRI to examine whether there was a relationship between depression, as measured with the Beck Depression Inventory (BDI-II), and the voxel-based morphology or functional connectivity in regions previously identified as involved in emotional regulation in patients following TBI. Patients were at least 4 months post-TBI (M ± s.d. = 15.13 ± 11.67 months) and the severity of the injury included mild to severe cases [Glasgow Coma Scale (GCS), M ± s.d. = 6.87 ± 3.31]. Results Our results showed that BDI-II scores were unrelated to voxel-based morphology in the examined regions. We found a positive association between depression scores and rs-fc between limbic regions and cognitive control regions. Conversely, there was a negative association between depression scores and rs-fc between limbic and frontal regions involved in emotion regulation. Conclusion These findings lead to a better understanding of the exact mechanisms that contribute to depression following TBI and better inform treatment decisions.

Probe Analysis

Electron probe analysis of frozen dried cryosections of frog skeletal muscle, rabbit vascular smooth muscle and of isolated, hyperpermeab1 e rabbit cardiac myocytes has been used to determine the composition of the cytoplasm and organelles in the resting state as well as during contraction. The concentration of elements within the organelles reflects the permeabilities of the organelle membranes to the cytoplasmic ions as well as binding sites. The measurements of [Ca] in the sarcoplasmic reticulum (SR) and mitochondria at rest and during contraction, have direct bearing on their role as release and/or storage sites for Ca in situ.

Purpose Nationwide, upward trends exist in student issues with anxiety, stress, depression, and lowered classroom performance. As emotional awareness and emotional regulation skills are typically not addressed in professional discipline-specific courses, students experience challenges in their academic performance. This pilot research explored the effect of brief targeted classroom practices within an empowerment-based framework on domains of emotional intelligence. Method Twenty-two students in an undergraduate speech-language pathology class received a 13-week, biweekly, 15-min session of empowerment-based worksheet exercises to develop increased self-esteem, emotional awareness and regulation, and communication. Assessments of self-esteem, emotional intelligence, communication competence, and communication apprehension were conducted using validated scales, namely, the Rosenberg Self-Esteem Scale ( Rosenberg, 1965 ), the Quick Emotional Intelligence Self-Assessment ( Mohapel, 2015 ), the Self-Perceived Communication Competence Scale ( McCroskey & McCroskey, 2013 ), and the Personal Report of Communication Apprehension ( McCroskey, 1982 ), respectively. Midsemester and semester-end student reflections were collected. Results Paired t tests were significant in self-esteem and emotional quotient, including subdomains of emotional awareness, emotional management, social emotional awareness, and relational management. Significance was noted in communication competence in the subdomains of dyad interaction, stranger interaction, and acquaintance. Students' reflection showed significant improvement in empowerment and self-rated improvements in confidence, communication, connections with peers, and trust with instructor. Conclusion Preliminary evidence demonstrates positive outcomes with integration of intentional classroom exercises to build emotional intelligence (including emotional awareness and regulation), self-esteem, and communication. This empowerment model may assist faculty in developing effective pedagogical strategies to build students' self-resiliency.
