Dr. Guorong Wu was part of an interdisciplinary team that was just awarded a SOM Team Science grant for the project “Energy allocation between brain and periphery in children with and without obesity.” Pediatric obesity is increasingly viewed as a brain-related condition, as higher BMI in children is linked to...

With bittersweet emotions, we share that Kenan Penaskovic, MD, has accepted the position of Chair of Psychiatry at the University of Kentucky, beginning in July.   Dr. Penaskovic first joined UNC in 2004 as a psychiatry resident and later served as chief resident.

I completed my psychiatry residency at UNC and am excited to be joining as a faculty member focusing primarily on outpatient care.

Abnormally increased extra-axial cerebrospinal fluid (EA-CSF) volume is present as early as 6 months in infants later diagnosed with autism and is associated with symptom severity at the age of diagnosis, but it is unknown whether early EA-CSF enlargement has long-term impacts on other clinical domains. Executive function (EF) deficits...

This international guideline reviews updated evidence on the safety of low-intensity transcranial electrical stimulation (tES), concluding that it is generally safe and well tolerated across healthy and clinical populations when used within established parameters. It also provides practical recommendations addressing ethical, regulatory, and application standards for research and clinical use.

tECS introduces a new class of brain stimulation: transcranial endogenous current stimulation. Unlike conventional stimulation that applies synthetic rhythms, tECS uses naturalistic, EEG-derived waveforms that mirror the brain’s own dynamics, offering a mechanistic route toward more personalized and biologically informed neuromodulation.
