Rather than focusing on response onset, we characterize the activation window of each visual area. The figure reveals a clear temporal hierarchy across the visual cortex, from earlier activation windows in V1 to progressively later ones in higher visual areas.

👁️🧠🧪 Vision takes time. But how does visual information flow through the human brain? Our new PLOS Computational Biology paper uses population receptive field (pRF) modelling to bring the spatial precision of fMRI to MEG, revealing the temporal dynamics of visual areas. 📖 doi.org/10.1371/jour...

In sports, we celebrate 1st, 2nd, 3rd. Everyone else gets lumped together. Why? Using 7T MRI, pRF modelling, and artificial neural networks, we show that tuning underlies ordinality perception, with most neural populations preferring early ordinalities. doi.org/10.1523/JNEU... 🧪🧠

Werner Reichardt, credited with discovering the neural circuitry for motion detection in the retina in the 1950s, did so on borrowed time.
As a young student, Werner Reichardt was a pupil in the laboratory of Hans Erich Hollmann, a pioneer of ultra-shortwave communication. Because of his knowledge he was drafted in 1941 to the German air force as a radio technician.There he met members of the resistance and established a covert radio connection with the Western Allies. In 1944 Reichardt was arrested by the Gestapo and sentenced to death, but escaped, and hid in Berlin until the end of the war.

It’s ironic that amid huge cuts to science and education funding and enforcement of Dutch-only programs, extra money is spent attracting US scientists. I support international collaboration, but without investing in our own students and education, science can’t thrive. www.nwo.nl/en/news/upda...

Update on the fund for leading international scientists: advance announcement of the Tulip Fund | NWO
NWO has made 25 million euros available to facilitate the transition of top international researchers to the Netherlands. Later this summer, the call for proposals for the Tulip Fund, as the new fund will be called, will open. The fund will enable renowned international scientists from outside the EU to continue their research at a Dutch research institution. Knowledge institutions can nominate top researchers or talents who wish to continue their work here in the Netherlands due to the growing threats to academic freedom to be considered for funding.
