Arachidonic acid (AA) is involved in signal transduction, neuroinflammation, and production of eicosanoid metabolites. The AA brain incorporation coefficient (K*) is quantifiable in vivo using [11C]AA positron emission tomography, although repeatability remains undetermined. We evaluated K* estimates obtained with population‐based metabolite correction (PBMC) and image‐derived input function (IDIF)...
Potassium channels play an important role in modulating synaptic activity both at presynaptic and postsynaptic levels. We have shown before that presynaptically located KV and KIR channels modulate the strength of corticostriatal synapses in rat brain, but the role of other types of potassium channels at these synapses remains largely unknown. Here, we show that calcium‐dependent potassium channels...
Despite much research, bipolar depression remains poorly understood, with no clinically useful biomarkers for its diagnosis. The paralimbic system has become a target for biomarker research, with paralimbic structural connectivity commonly reported to distinguish bipolar patients from controls in tractography‐based diffusion MRI studies, despite inconsistent findings in voxel‐based studies. The purpose...
