Application of the Force-velocity-power Concept to the 3-min all-out Running Test.

Force-velocity-power (FVP) profiling offers insights related to key factors that may enhance or hinder sprinting performances. Whether the same FVP principles could be applied to the sprinting portion of the 3-minute all-out test for running (3MT) has not been previously investigated. Twenty moderately trained participants volunteered for the study (age: 24.

Enhanced subgenual cingulate response to altruistic decisions in remitted major depressive disorder.

Background: Major depressive disorder (MDD) is associated with functional abnormalities in fronto-meso-limbic networks contributing to decision-making, affective and reward processing impairments. Such functional disturbances may underlie a tendency for enhanced altruism driven by empathy-based guilt observed in some patients. However, despite the relevance of altruistic decisions to understanding vulnerability, as well as everyday psychosocial functioning, in MDD, their functional neuroanatomy is unknown.

Increased amygdala responses to sad but not fearful faces in major depression: relation to mood state and pharmacological treatment.

Objective: Increased amygdala response to negative emotions seen in functional MRI (fMRI) has been proposed as a biomarker for negative emotion processing bias underlying depressive symptoms and vulnerability to depressive relapse that are normalized by antidepressant drug treatment. The purpose of this study was to determine whether abnormal amygdala responses to face emotions in depression are related to specific emotions or change in response to antidepressant treatment and whether they are present as a stable trait in medication-free patients in remission.

Method: Sixty-two medication-free unipolar depressed patients (38 were currently depressed, and 24 were in remission) and 54 healthy comparison subjects underwent an indirect face-emotion processing task during fMRI.

Reversed frontotemporal connectivity during emotional face processing in remitted depression.

Background: Vulnerability to relapse persists after remission of an acute episode of major depressive disorder. This has been attributed to abnormal biases in the processing of emotional stimuli in limbic circuits. However, neuroimaging studies have not so far revealed consistent evidence of abnormal responses to emotional stimuli in limbic structures, such as the amygdala, in remitted depression.

Reduced medial prefrontal responses to social interaction images in remitted depression.

Context: Major depressive disorder is associated with impairments in processing emotional stimuli, and residual impairments are observed during remission, possibly indicating trait vulnerability. Stimuli with social context represent a distinct class of emotional stimuli, which in healthy volunteers are associated with specific neural substrates but have not previously been studied relative to vulnerability to depression.

Objective: To explore whether individuals with remitted major depressive disorder had altered neuronal processing of social emotional stimuli.

Brain imaging correlates of cognitive impairment in depression.

This review briefly summarises recent research on the neural basis of cognition in depression. Two broad areas are covered: emotional and non-emotional processing. We consider how research findings support models of depression based on disrupted cortico-limbic circuitry, and how modern connectivity analysis techniques can be used to test such models explicitly.
