In @MATLAB , we often iteratively write into new variables. When you don't know the variable's size, you can still preallocate memory by simply inverting the loop, e.g. clear tmp for i = n:-1:1 tmp(:,i) = ...; end This will then allocate memory in the first call. #matlabtips

Hi #SfN2018 people, come by our posters FF6 and FF7 Sunday afternoon! We identified 49 interpretable behavioral dimensions from similarity judgments for 1,854 object categories. Also, we developed a high-quality large-scale object image database with more than 26,000 images!

Nice! Be at a conference, have home made lunch, see your baby, and (well, maybe) work on ethics approval & collect Mturk data - what else could I wish for? #neuromatch2020

With fMRI, it's fascinating to compare results at a group level to individuals. More subtle effects found in most or all individuals can disappear. I'm wondering how prevalent this is, simply because people don't have enough statistical power at the individual level.

@ISDedal If you get along well with your PhD advisor, they have the funding, and you can continue to be productive, then delay your PhD defense for as long as possible. In most German states, the clock starts ticking only after your PhD.

In my opinion by far the best image reconstruction from brain activity patterns out there. Not only good semantic reconstruction as in many of the current approaches but also nice fidelity of object position and scene layout.

Let's do TLDR for our new preprint! Brain-Diffuser We reconstructed perceived scene images from brain signals. These reconstructions capture both layout and semantic information of images... But how?

Jack Gallant @gallantlab : three different views based on what understanding is based on physics, cognitive science (information processing) and decoding/prediction. Deep nets maybe not consistent with first two views of understanding. #ccn2018 #ccn18

Happy to see this amazing work by Pinglei Bao @bobking and @doristsao out in @nature . They discovered a general organizing principle underlying macaque IT in response to objects, revealing two new object-selective networks & allowing object reconstruction.

Doing something that has not been done before can often yield valuable insights. But the fact that something has not been done before in and of itself is in many cases not a good motivation for a study.

If I have large neuroimaging and behavioral datasets that I would like to share (say fMRI, MEG, ECoG, monkey, behavior), what is the best place to put them? I really like @OpenNeuroOrg but is it only so slow for me? What about @figshare ? Other well known places that I'm missing?

Today I was contacted by a music researcher regarding my high school thesis on overtone singing that I wrote 20 years ago. I happened to be in contact with composer Karlheinz Stockhausen and our conversation was the only literal proof that he invented it independently. 1/2

Cultural difference: in the US, it appears to be perceived as ethical and is often required to collect information about race, while in Germany most would be outraged about this question, for obvious historical reasons.
