We are delighted to share that Jingjie Li (@jerlich Lab) and Ella Svahn (@macaskillaf Lab and Athena Akrami Lab), have been awarded the Jon Driver Prize!
This prize recognises outstanding research from UCL neuroscientists at the PhD level.
Join the UCL Neuroscience Symposium on 18 June, when Jingjie and Ella will be presenting their research:

@albertcardona hey, I'm waiting for you to assign me the eLife paper, so I can start to get reviewers!
“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
If you know simulation based calibration checking (SBC), you will enjoy our new paper "Posterior SBC: Simulation-Based Calibration Checking Conditional on Data" with Teemu Säilynoja, @marvinschmitt.com and @paulbuerkner.com

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.

#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!

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!

This seems important. A new catalytic process converts CO2 to ethanol or acetic acid. https://phys.org/news/2024-05-catalyst-carbon-dioxide-industrial-emissions.html
