Neural tuning for ordinal processing: convergent patterns in human brains and artificial networks Processing ordinality, i.e., the rank of an item in a series such as 1st, 2nd, 3rd, etc., is a fundamental skill shared by humans and animals. While humans often use symbolic sequences like numbers or...

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.

Numerosity adaptation suppresses early visual responses Communications Biology - Numerosity adaptation suppresses monotonic neural responses to numerosity displays in the early visual cortex, with more suppression for higher numerosity adaptors....

Excited to share that my first article is now published in Communications Biology!
Humans and many animals have an innate ability to rapidly perceive numerosity—the number of objects in a visual scene. But how does our brain process this fundamental capability?

We combined psychophysics, 7T fMRI, and computational modeling of vision with placebo, 5mg, and 10mg psilocybin, in the same group of participants, to clarify the computational mechanisms of psychedelics. 🧵

Numerosity adaptation suppresses monotonic neural responses to numerosity displays in the early visual cortex, with more suppression for higher numerosity adaptors. Therefore, numerosity adaptation effects begin in early sensory stages of processing.

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.

Werner Reichardt, credited with discovering the neural circuitry for motion detection in the retina in the 1950s, did so on borrowed time.
