This finding suggests a novel and efficient strategy of using only task-based data to estimate networks within an individual’s own anatomy as well as estimate the task response within those networks. (9/13)

By pooling extensive resting-state and task data, we were able to triple the amount of data available for analysis within each individual, enabling precise mapping of five higher-order association networks within the thalamus. (6/13)

Amazing work led by Jingnan! Pooling in task and rest data can give us a lot of discovery potential like discovering hard to find networks in the thalamus (bulk of my postdoc work with Randy). Task data can be used to define networks and activations from left out runs can be investigated. Cool work!

We also kicked off our very first data collection for the Precision Imaging study — exploring brain dynamics through EEG 🧠⚡

Excited and grateful to see this amazing group of researchers and trainees working to understand the complexities of the human brain

So true. It's my fourth week of teaching here, I am still struggling before every class.

Hoping that one day meditation science would be as advanced as the science on exercise and this work is some efforts towards that.

So, how does this help? It furthers the science towards objective measures of the degree and depth of meditation. And once we can measure it, we can improve it. It might be helpful for those interested in taking their meditation experiences to a deeper level.

The dynamics would represent a slowing down of brain processes but unlike sleep which is shown by even slower oscillations. It can be understood as a stage between fully awake and sleep, something which ancient texts on Yoga have pointed out as Turiya.

Compared to control participants who are listening to relaxing music where nothing drastic is happening.

Also, the aperiodic signals (1/f slope) have a sharp change in exponent during the relaxation phase - the spectrogram flattens out.

Something interesting is happening in the brain during SKY. The breathing period triggers theta oscillations in the brain, which leads to an increase in low theta and delta oscillations during the meditation period coupled with a sharp decrease in alpha oscillations.

Glad to share that our study on the brain dynamics during rhythmic breath-based meditation is finally published in npj Mental Health Research. Here, we studied EEG on Sudarshan Kriya Yoga (SKY) practice on 43 subjects.

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!

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!

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.
