Abstract: OBJECTIVE Phosphodiesterase-5 inhibitors (PDE5Is) enhance vasodilation. We investigated the effects of PDE5I on cerebral hemodynamics during cognitive tasks using functional near-infrared spectroscopy (fNIRS). METHODS This study used a crossover design. Twelve cognitively healthy men participants… read more here.

DOI: 10.1002/brb3.70795
Abstract: Tinnitus, a self‐reported perceptual disorder, is currently believed to arise from maladaptive plasticity due to reduced sensory input. While deep brain stimulation (DBS) has shown promise in alleviating tinnitus‐related behaviors, its effects on neuronal activity… read more here.

DOI: 10.1002/brb3.886
Abstract: Categorization is a fundamental cognitive process, whereby the brain assigns meaning to sensory stimuli. Previous studies have found category representations in prefrontal cortex and posterior parietal cortex (PPC). However, these higher‐order areas lack the fine‐scale… read more here.

DOI: 10.1002/cne.24986
Abstract: The anterior cingulate cortex (ACC) is important for decision‐making as it integrates motor plans with affective and contextual limbic information. Disruptions in these networks have been observed in depression, bipolar disorder, and post‐traumatic stress disorder.… read more here.
