Mitochondrial CHCHD2: Disease-Associated Mutations, Physiological Functions, and Current Animal Models

Rare mutations in the mitochondrial protein coiled-coil-helix-coiled-coil-helix domain containing 2 (CHCHD2) are associated with Parkinson’s disease (PD) and other Lewy body disorders. CHCHD2 is a bi-organellar mediator of oxidative phosphorylation, playing crucial roles in regulating electron flow in the mitochondrial electron transport chain and acting as a nuclear transcription factor for a cytochrome c oxidase […]

Neural Coding of Cognitive Control: The Representational Similarity Analysis Approach

Cognitive control relies on distributed and potentially high-dimensional frontoparietal task representations. Yet, the classical cognitive neuroscience approach in this domain has focused on aggregating and contrasting neural measures – either via univariate or multivariate methods – along highly abstracted, 1D factors (e.g., Stroop congruency). Here, we present representational similarity analysis (RSA) as a complementary approach […]

More belly weight increases danger of heart disease even if BMI does not indicate obesity

Research on how obesity impacts the diagnosis, management and outcomes of heart and blood vessel disease, heart failure and arrhythmias is summarized in a new statement. Waist circumference, an indicator of abdominal obesity, should be regularly measured as it is a potential warning sign of increased cardiovascular disease risk. Interventions that lead to weight loss […]
