In preparation for our #CCN2023 @CogCompNeuro GAC next week, I’m going to do some polls here this week to take the temperature of the room. 🌡️

Very curious to see the range of answers so please pass it on 🔁🙏 and feel free to elaborate - we'll try to take any discussion into account at the workshop

This is not how to deal with climate change.

Wow. Great to see the community continue to take scientific fraud seriously. This was about high profile papers on Alzheimer’s disease.

Fourier analysis uses sinusoids as basis function. I have seen this argument sometimes (explicit and implicit): given that for brain data Fourier analysis returns non-zero coefficients across all frequency bins, this means that there are lots of oscillators in the brain (1 per examined frequency).

I thought of following demo to illustrate the aspect that jumping from a measure directly to physiology is tricky: instead of sinusoids, use triangular functions 🔺 to represent the signal. It's definitely possible to reconstruct signals that way, achieving a good to fantastic fit (can make the signal + reconstruction curves indistinguishable by just piling on more terms).

Does that mean that there are lots of triangular oscillators in the brain? I would say no. 🙃

Hi all, instead of a re- #introduction after moving instances, I'd like to introduce you to my graduate student Peter Salvino, who passed away under tragic circumstances last week.

Because of his way too early passing, most of you didn't get to know him. So I wanted to make sure my #neuroscience community knows how brilliant and kind a scientist he was. Peter wore many hats in the lab. Being my very first student, he built with me, and knew the ins and outs of every bit of hardware and software. He was also a masterful engineer and inventor, and had a keen scientific mind. He knew what the big questions in the field were and was completely fearless in going after them. We will slowly publish all his great contributions, so you will read his name again.

Most importantly, he was so generous to his lab mates. He helped every single person in the lab, with such selflessness and genuine humbleness. He was really loved by all of us. This is such a huge loss to our field. He was destined to greatness.

Peter's family has set up a GoFundMe campaign to help support research similar to his at Northwestern. They welcome any contributions to honor the memory of this amazing human being.
