Grateful to see our Parkinson’s research at the University of South Dakota featured in the Press & Dakotan. We’re studying individualized, EEG-guided TMS to target brain rhythms linked to gait and balance difficulties. Thanks to our participants, team, and funders!

Small pilot study (n=17) conducted by @narayananlab & collaborators suggests that 4 Hz subthalamic nucleus stimulation can improve performance in people with #Parkinsons with cognitive impairments (compared to DBS OFF or ~130 Hz STN DBS) nature.com/articles/s41531-0…

Excited for this webinar on Computational Properties of the Prefrontal Cortex from the Journal of Neuroscience: neuronline.sfn.org/scientifi… @SfNtweets

Computational Properties of the Prefrontal Cortex

“Ultimately, the investigation of prefrontal cortex function is fundamentally an effort to understand prefrontal computations” (Narayanan, et al. 2025).

Credits go to my world-class team. I am especially grateful to my mentors who inspired and supported/funded my academic curiosity. Our goal remains: to bridge the gap to human studies and better understand the link between neurophysiology and subjective experience ❤️

Excited to share our latest paper in @TheJournal_Pain, led by my dear friend @oliverflouty (@USouthFlorida)! jpain.org/article/S1526-5900… Using #ECoG in 4 sheep, we explored supraspinal effects of high-frequency #spinalcordstimulation—revealing region- and frequency-specific modulatory patterns. Congrats to the whole team! @VBharmauria17 @NourShaheen_MD

Our latest work: biorxiv.org/content/10.1101/… We show that corticostriatal ramping activity can't readily be explained by movements using motion tracking, and that ramping can't readily be explained by reward anticipation in mice performing timing and Pavlovian tasks.

Timing, movement, and reward contributions to prefrontal and striatal ramping activity

Across species, prefrontal and striatal neurons exhibit time-dependent ramping activity, defined as a consistent monotonic change in firing rate across temporal intervals. However, it is unclear if...
