Targeting intracranial electrical stimulation (ES) to network regions defined within individuals causes network-level effects

By Cyr et al.

***
Q: Can we use individualized network maps from precision fMRI to modulate a targeted network via intracranial ES?

A: Yes!

Dynamic task-based reorganization of sensory-biased and supramodal working memory networks in the human cerebral cortex Sensory working memory is supported by a distributed set of brain regions. Visual working memory and auditory working memory recruit different networks, which include posterior sensory cortices and mu...

My 1st first (co)author paper is up on BioRxiv!

How does functional connectivity in the human cortex differ during visual and auditory working memory (WM) tasks? Do those changes correlate with behavior? We take a stab at some answers:

Fascinated and inspired by the book. Also, because I have an Erdos number of 5, so have some connection to the genius mathematician.

Another thing I liked about his approach to problem solving was that he said that truly wonderful problems tend to fight back. This is true for most sciences; the things worthy of knowing will take their time, so you have to be patient and determined.

developed that fascination in those who came in contact with him. One thing that caught my attention was his claim that mathematics is infinite; even when physics, biology, and possibly neuroscience are solved, there would still be mathematics to work on.

He was truly focused on mathematics, worked 19 hours a day, would reach to some mathematician's place unannounced and say "My brain is open" as a means to start collaboration. He had his eccentricities, but he loved his field more than anything and

I usually don't get time to read books as much as I would like. Had the opportunity the read one while traveling last few days "The Man Who Loved Only Numbers", a fascinating read about one of the most productive and collaborative mathematicians ever, Paul Erdos!

We are hosting an outreach program in Chicago and Bay area, interested people can check it out here: iitgn.ac.in/assets/pdfs/...

Work done by an amazing team Dr. Suruchi Fialoke, Prof. Rahul Garg, Kushagra Rode, Aniruddha Deb from IIT Delhi.

Like in this analysis of the Pieman audio dataset, specific interesting scenes in the movie elicited strong responses across individuals, which TSA nicely captures nicely.

This is where our method TSA comes into the picture, it is a model free analysis technique that allows cognitive scientists to find robust and nonlinear brain activations across a whole range of cognitive tasks thus opening up the avenues for more naturalistic task designs.

The gold standard of the field has been General Linear Model (GLM) which allows to find strong, reliable activations but it is limited by model assumptions such as linear behavior of the brain. But the brain is highly non-linear especially in higher order brain regions.

Usually Blood Oxygenation Level Dependent (BOLD) data acquired through fMRI is slow and sluggish. To determine if a brain region is involved in a given cognitive task, careful task design and methods are required.

Excited to share our new preprint called "Temporal Synchronization Analysis: A Model-Free Method for Detecting Robust and Nonlinear Brain Activation in fMRI Data".

The less jargon in your paper, the simpler it feels, and the harder it gets to be accepted 🤷.

Would love to write easy-to-access papers though.

- I got my office ready
- The first version of the lab website launched
- Created lab design requirements
- Attended a Robotics symposium

Lots of exciting science and teaching happening!

- One paper was accepted
- One paper is being finalized
- One paper reviewed
- Lots of faculty meetings
- Met with a Japanese delegation
- One Qualifying exam attended
- Acted as an external on postdoc interviews

- Met with 20+ students about positions in the lab
- Attended MSc. Mid-Sem thesis presentations
- Proposed two courses for the next year
- Applied for two external research grants
- Wrote Ethics Committee proposal for five research projects

It has been a month since I joined IIT Gandhinagar, so much goes behind Professoring that people don't usually see. Highlighting all the activities of the past month:
- Interviewed about 50 candidates for the MSc program at Cognitive & Brain Sciences at IITGN

We are also hiring Postdocs, so reach out if interested (the ads would be out in couple of weeks).

If you are a Bachelors/Masters student and would like to do a project or thesis (atleast 4 months), please reach out.

We are hiring PhD students through the IIT GN PhD program (the deadline is 26th March, 2025, 5 PM IST). If interested, please apply.

We investigate the localization and dynamics of various cognitive functions, how these processes are disrupted in cognitive disorders, and whether predictive models can be developed to better understand and diagnose these conditions. 😁 😇

Our lab website is up and running.
