A new imaging technique has the potential to detect neurological disorders–such as Alzheimer's disease–at their earliest stages, enabling physicians to diagnose and treat patients more quickly. Termed super-resolution, the imaging methodology combines position emission tomography (PET) with an external motion…

Adaptive brain response to stress—and its absence—in people with depression
A new study identifies a novel biomarker indicating resilience to chronic stress. This biomarker is largely absent in people suffering from major depressive disorder, and this absence is further associated with pessimism in daily life, the study finds. Nature Communications…

Neuropathology of COVID-19 patients caused by infection of brain pericytes
Coronavirus disease 2019 (COVID-19) primarily causes respiratory symptoms that range from mild cough and fever to severe pneumonia. Increasingly, studies indicate that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has an organotropism beyond the respiratory tract and that the…

New brain stimulation technique precisely controls motor activity without surgical device implantation
Neurological disorders such as Parkinson's disease and epilepsy have had some treatment success with deep brain stimulation, but those require surgical device implantation. A multidisciplinary team at Washington University in St. Louis has developed a new brain stimulation technique using…
