“You can’t just be confident, you have to be confident about something.”
Research led by @jerlich and Xiaoyue Zhu in @nbdt_journal set out to disentangle the different kinds of confidence by designing a perceptual gambling task for rodents.

Elsevier/RELX profit rises 10%, investor call: "continuing to see strong growth" including from pay-to-read and pay-to-publish. From the www.journalology.com newsletter.
In my opinion, more researchers and universities need to stop supporting them. One way to help is to join the Free Journal Network https://fediscience.org/@alexh/114055607398246074

@adredish @pluralistic since online shopping is already dynamic it makes sense for stores to match. Probably you put items in your cart by scanning the QR code with your phone so that’s the price you get.

How does that "individual pricing in grocery stores" work? Does that mean the price can change from the time you take it off the shelf to the time you check out? How does that match the "economic agreement"? (which depends on full information on both sides).
At least airplane and online store prices lock in the individual price when you select it. It doesn't suddenly change at the payment page. Although, I'm sure that's the next enshitification step...

A hardy and hale "huzzah!" to Emery N. Brown on receiving the National Medal of Science! It’s the nation’s highest honor for scientists and engineers.

New findings: We track visual sequences yet the brain's process is unclear. We discovered the sequence-tracking area in monkey's lateral prefrontal cortex is distinct from an adjacent subregion that reacts to other stimulus changes. #neuroscience 🧠 🧪 👩🔬

A computational #NeuralNetwork model leverages a simple unsupervised learning principle to account for recent findings on when memories move apart (differentiate) or together (integrate) in the brain. #Neuroscience https://elifesciences.org/articles/88608?utm_source=mastodon&utm_medium=social&utm_campaign=organic

It took me ~a year to translate Neurodata Without Borders to linkml+pydantic with full abstraction over array/storage backend. Now that I did that, it is taking me ~hours to make interfaces to put NWB in SQL dbs, web APIs for editing and serving NWB datasets (where you can download arbitrary slices of the individual datasets instead of a bigass 100GB HDF5 file), and interconversion between hdf5, dask, and zarr.
Anyway open data in neuroscience is about to get real good.

Task Context Shapes Short-Term Memory Localisation
Go see our very exciting results demonstrating the sensitivity of working memory strategies to task context. We made two variations of a classic 2AFC memory-guided orienting task : one that encouraged an egocentric strategy and one that encouraged an allocentric strategy. The results shocked us! M2 only involved in egocentric planning!

@ekmiller Well, we showed the rat SC is causally involved in abstract categorisation, so... not so surprised https://www.nature.com/articles/s41593-021-00865-x (cited as Ref 51)

Excited to share a new paper from the lab:
Encoding of 2D Self-Centered Plans and World-Centered Positions in the Rat Frontal Orienting Field
Activity in the M2 predicts upcoming choices. But what does the activity represent? A gaze-centered plan? A world-centered goal? A specific movement? We asked rats to plan responses to different targets from different start position to find out!

@david1 huh? Biden won the 2020 election. That doesn't mean people want him to run again now.
@adredish @UlrikeHahn @albertcardona
I would argue that the rise of GenAI demands more not less transparency. The "old" peer review system hides the process of approval, so once a paper is "peer-reviewed" it somehow has an air of legitimacy.
I share your concerns- but I think the solution involves networks of trust and more active science communication.
@adredish We disagree. I find it super informative to be able to read decision-letters. To see what careful readers came up with that I might have missed on a casual read.
