DTP is excited to share a new paper from Tate Poplin in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging. Tate is the first author and a current graduate student in our lab. This work was conducted during Tate’s prior role as a research assistant at the Laureate Institute for Brain Research in Tulsa, OK. The paper examines how transcranial direct current stimulation (tDCS) affects attention and threat processing in individuals with anxious depression. The study found that frontal tDCS enhanced task engagement and executive control—but also unexpectedly increased sensitivity to threat, highlighting the nuanced effects of neuromodulation in complex clinical populations. A BPCNNI press release about this study is linked in our bio!
