Article Synopsis
- The study investigated how major depressive disorder (MDD) affects the functional connectivity between the left and right amygdala, particularly looking at the medial sub-region in MDD patients compared to healthy controls.
- Findings revealed that MDD patients showed reduced inter-hemispheric connectivity in the medial amygdala, which correlated with the severity of depressive symptoms and emotional processing abilities.
- Additionally, the medial amygdala's connectivity levels could predict treatment responses to SSRIs in over 65% of cases, highlighting the importance of this brain region in understanding depression.
Article Synopsis
- Calluses are thickened skin areas formed due to friction or irritation, typically harmless but can lead to infections if untreated.
- The article explores the effectiveness of thermal imaging in assessing calluses, showing that temperature drops in the skin can indicate the presence of calluses.
- Experimental validation supports the idea that a temperature decrease of 0.5°C or more can signal callus presence, emphasizing the need to consider ambient temperature during assessments.
Introduction: Recently, interest has emerged in subjective cognitive decline (SCD) as a potential precursor to Alzheimer's disease (AD) dementia. Whether individuals with SCD harbor brain alterations in midlife, when AD-related pathology begins, is yet to be elucidated. Furthermore, the role of apolipoprotein ε4 ( ε) allele, a robust AD risk factor, in the relationship between SCD and brain alterations is unknown.

Methods: We examined the difference in HoFC, computed as the correlation between atlas-based regions and their counterpart on the opposite hemisphere, in 16 moderate-severe traumatic brain injury patients (msTBI) and 36 healthy controls. Regions of decreased HoFC in msTBI patients were further used as seeds for examining differences between groups in correlations with other brain regions.
Background: Arousal and awareness are two important components of consciousness states. Functional neuroimaging has furthered our understanding of cortical and thalamocortical mechanisms of awareness. Investigating the relationship between subcortical functional connectivity and arousal has been challenging owing to the relatively small size of brainstem structures and thalamic nuclei, and their depth in the brain.
