Research Focus
Dr. Nandakumar Narayanan's lab at the University of Iowa focuses on understanding cognitive impairment in Parkinson's disease (PD). They study how brain rhythms relate to attention, memory, and cognitive control in PD patients, with the goal of developing new treatments. By exploring the interactions between brain activity, genetics, and novel therapies, the lab aims to improve the quality of life for individuals with PD and related dementias.

Research Aims
3AIM 01Determine the structural basis for deficits in frontal midline delta/theta rhythms in PD.
AIM 02Assess the predictive power of these rhythm deficits in relation to cognitive function in PD.
AIM 03Investigate the effects of tuned low-frequency deep brain stimulation on cortical activity and cognition.

Career totals from OpenAlex, compared against labs that share a department. A department spans everything from one paper to tens of thousands, so bar heights are on a log scale — otherwise the largest lab would flatten every other bar to a line.
