Our lab is looking for someone with signal processing expertise of time-series data obtained from intraoperative and chronic Human ECoG/EEG recordings. The position is funded for 3 years at least, and the salary is 100K$. Please retweet or message me directly if interested.

Our lab is looking for a postdoc or a fresh PhD who is well versed in signal processing of neurophysiology EEG/ECoG time-series data. We have large datasets waiting to be explored and collaborators from 🏴󠁧󠁢󠁥󠁮󠁧󠁿 🇨🇦 and 🇺🇸 . Please message me directly if interested. #neurotwitter

Th Human Brain is a marvel to behold! On the left is a picture of an exposed brain during electrode implantation surgery. On the right is the virtual brain reconstructed from the patient's scans before and after surgery. Can you identify the arrows in yellow? #medtwitter

In our latest article in The Lancet Reg Health-Americas, we've uncovered trends&disparities in #DBS use, with most prominent disparity being #AfricanAmerican status across all main DBS indications Krembil Brain Institute University of Toronto Neurosurgery U of T News Alfonso Fasano Mojgan Hodaie kalialabs thelancet.com/journals/lanam…

Wishing a very happy Valentine’s Day to our amazing movement disorder team, our incredible patients, and our valued referring providers. At USF/TGH, we’re proud to deliver world-class care within one of the nation’s busiest functional programs. #ValentinesDay INSIGHTEC

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 ❤️

A very important study demonstrating a clear direct neural projection from the prefrontal cortex to the subthalamic nucleus for the first time in Human beings and its role in cognition. #narayananlab #iowaneurosurgery #hyperdirectpathway x.com/iowamed/status…

iMRI Vs MER for STN DBS (45 patients). Turns out that iMRI was associated with better anatomical accuracy while MER was associated with lesser side effect threshold during the initial programming. All other clinical and functional outcomes were similar. frontiersin.org/articles/10.33…

We need MER to study brain circuitry and understand how the brain works in the normal and diseased states

An independent group showed that STN-DBS at theta can improve cognitive control: ow.ly/nnSf30jmgMK. Similar to Ryan/Oliver's recent work: ow.ly/gv9V30jmgV6!
