Yesterday at #ICON2025 I got to present our poster with #EttoreAmbrosini, @palencianoap.bsky.social, and @mruz.bsky.social on flexible task representations. I loved the chance to share our preliminary results and hear such thoughtful feedback!

👩‍💻 New preprint out (FIRST one of my PhD journey) with the incredible @lindedomingo.bsky.social @ortiztudela.bsky.social @gonzalezgarcia.bsky.social

"From sudden perceptual learning to enduring engrams: A representational perspective" 🧠

doi.org/10.31234/osf...

🧠New preprint!
We show that different priorities shape the neural coding of planned actions in working memory. Using EEG+RSA, we find that expected interference leads to anticipatory changes in representational geometry, beyond simple maintenance.

The what and when of visual surprise:
EEG shows that high-level visual surprise emerges rapidly and modulates neural responses ~200ms after stimulus onset.

A photo of a woman at a protest wearing red, white, and blue and a cowboy hat while holding up a sign with imagery of drag queens also wearing red, white and blue and the words "NO KINGS" with other protesters visible in the background behind her.

A photo of a man at a protest holding a large American flag while wearing a shit with a sign on the back of it with an illustration of Donald Trump as a clown wearing a crown and the words "NO CLOWN KINGS" and "In Union there is STRENGTH."

A photo of protesters with fists raised and mouths open, some holding up signs including one with imagery of Donald Trump as Kim Jong Un and the words "KIM JONG DON - THE REAL CRIMINAL."

A photo of many people at a protest holding anti-Donald Trump signs and American flags, including some dressed as clowns and their faces painted orange.

This is fucking insane

🧠En el seminario hoy la investigadora Ana Paqui @cimcyc.bsky.social nos ha presentado una charla muy interesante sobre #neurosexismo a través de la revisión de trabajos científicos publicados a lo largo de los años, lo que ha dado pie a una enriquecedor debate.

¡Muchas gracias por venir! 👏

YouTube video by UGRmedia Johannah Völler gana el concurso 3MT en la UGR

Plot twist 😮, memory 🧠and AHA moments🤓: what do they have in common? Johannah Völler, our PhD student, explains!

If you don't want to lose her #3MT speech, let's watch this video 👇

www.youtube.com/watch?v=Dkff...

🎉 3 of our PhD students participated in the #3MT competition, and Johannah Völler (Human Neuroscience Research Lab) won! 🥇

📢 Her thesis “focuses on how we learn in a single trial and how the emotional experience (”Aha!“) associated with these learning moments facilitates memory consolidation"

El martes 25 de marzo nos vemos en la Sala Planta Baja #Granada con una nueva sesión de Psycho Beers 🧠🍻

La unión de Psicología e IA promete una noche de conocimientos con Javier Ortiz Tudela, investigador del CIMCYC, y Belén Prados, de la ETS de Ing. Informática y de Telecomunicación de la UGR.

Nice coverage of the Fort Collins #StandUpForScience2025 march at www.coloradoan.com/story/news/l...
1000 scientists standing up and fighting back against the Trump administration's politically motivated censorship of science and attempts to destroy health and economy of our communities.

Olive oil and sugar, the Andalusian spirit is felt at CIMCYC! 🎉

Today, we celebrate #Andalusia and our luck of being located in #Granada with a breakfast of toast, coffee and fellowship.

An upside-down American flag hangs from El Capitan near Yosemite National Park’s Horsetail Fall on Saturday to protest the thousands of federal job cuts made by President Donald Trump’s administration. Tracy Barbutes/Special to the Chronicle

Brilliant protest. Yosemite National Park workers hung an upside-down American flag — traditionally a symbol of distress or a national threat — thousands of feet off the ground on the side of El Capitan.

DeepSeek is the flip side of the same coin: It innovated because of, not in spite of, its constraints. And now that it has upended the assumptions of the dominant AI paradigm, we should reject its costly trade-offs and seek new ways to develop AI without so many harms. 24/
