Thank you Ravi!

Congratulations @renilmathew.bsky.social on a successful Ph.D. Exam. 2nd Menon lab doctoral defense in 10 days! This supervisor is exhausted!

Guess who's celebrating a 30th anniversary? With massive thanks to years of support from @westernu.ca @schulichmeddent.bsky.social @lhsccanada.bsky.social @braincanada.bsky.social @innovation.ca @brukercorporation.bsky.social Siemens Healthineers, Gov. of Ontario www.schulich.uwo.ca/about/news-e...

Heading to Montreal to give the Feindel Brain and Mind Seminar on Monday, May 4th. Honoured and touched, because Bill Feindel and I shared an office at @theneuro.bsky.social during my M.Sc. work at McGill. The work I will present comes from @renilmathew.bsky.social doctoral research.

How does blood flow relate to brain activity? We discovered that it reflects two neural populations affected oppositely by arousal. Together, they explain neurovascular coupling in all brain regions and brain states! Out today in Nature: rdcu.be/fdC2A @uclbrainscience.bsky.social

Excited to give the Feindel Lecture at The Neuro on Monday 26th Jan in Montreal. Streamed and recorded too. Come hear about our new SASS MRI technique just out in print in @natmethods.nature.com @westernuwin.bsky.social @theneuro.bsky.social

Our article on using non-steady-state scans for event related fMRI is now out in print (remember print?). www.nature.com/articles/s41... And as a bonus, the journal (Nature Methods), did a News & Views piece www.nature.com/articles/s41... Lead author @renilmathew.bsky.social

News and views article on SASS-fMRI from Nature methods. www.nature.com/articles/s41...

Taking advantage of non-steady-state imaging to increase temporal SNR for fMRI - Nature Methods

A technique called SASS increases temporal signal-to-noise ratio for functional MRI by taking advantage of the time it takes to reach steady state when collecting functional images.

Great honour to receive Dr Tutis Villis Graduate Award in Neuroscience. 🙏

Ravi Menon@northernthrux.bsky.social · 8mo ago

Congratulations to my student @renilmathew.bsky.social (Renil Mathew) on receiving the Dr. Tutis Vilis Graduate Award in Neuroscience. As a long time friend and colleague of Tutis, this award really brings a tear to my eye.

Just published my "Programming for Psychologists" course! 👩‍💻 github.com/Naubody/prog... Designed for Psychology & Cognitive Neuroscience Master's students starting their programming journey at @vuamsterdam.bsky.social. Feel free to share! Feedback welcome!

#WesternU researchers have unlocked the hidden potential in discarded MRI data, developing a new technique transforming how scientists study the brain. @schulichmeddent.bsky.social

Western University researchers have uncovered hidden potential in the historically discarded MRI data that is recorded in start-up period of scans.

Researchers at @westernu.ca have unlocked surprising power in the first seconds of a functional MRI scan. Short, deliberate pauses boost the signal that follows – producing sharper, more responsive images of brain activity. Published today in @natmethods.nature.com.

If the community wants, we have XA60 and VE12U versions we can make available as a C2P for Siemens scanners. And we have a Paravision 360 v3.6 available for Bruker. The processing code is equally simple and is posted with the paper.

14 months after submission, our article “Stimulus-modulated approach to steady state (SASS): a flexible paradigm for event-related fMRI" is now out in @natmethods.nature.com . You can read it here rdcu.be/ePJo6 It is the first first author paper from my student @renilmathew.bsky.social 👏🏽👏🏽👏🏽 …1/N

This article in The Transmitter covering our paper may be one of the best scientific content headlines of all time. www.thetransmitter.org/fmri/timing-...

Timing tweak turns trashed fMRI scans into treasure

Leveraging start-up “dummy scans,” which are typically discarded in imaging analyses, can shorten an experiment’s length and make data collection more efficient, a new study reveals.

Excited to share my first first-author paper in Nature Methods!🤩 A quest to solve fMRI–EEG interference revealed a hidden strength in the usually discarded “dummy” scans. That spark became SASS-fMRI — boosting sensitivity and enabling silent, flexible experiments. www.nature.com/articles/s41...

On this day in 1920, Dr. Frederick Banting woke at 2 a.m. in #LdnOnt and jotted down a 25-word idea — setting in motion the discovery of insulin. 105 years later, Banting's legacy continues. A heritage plaque at #WesternU now marks the historic moment. Learn more: www.uwo.ca/projects/her...

Thrilled to share that the central work of my PhD will be published soon.😬

A lot of hard work over a year went into this. Details to follow when the embargo lifts! What I can say is that good peer review can make a paper much better, even if it takes a year. And these peer reviewers were very helpful and constructive 🙏. You'll be able to read their comments online.
