4. A predictive coding perspective on oscillatory travelling waves

Andrea Alamia

9/18/25, 1:30 PM

This talk presents a few studies that aim to interpret oscillatory travelling waves in the predictive coding framework. In the first part, I’ll introduce a simple model of the visual cortex based on predictive coding mechanisms, in which physiological communication delays between levels generate alpha-band rhythms. Interestingly, these oscillations propagate as traveling waves across levels,...

3. Complex neuronal bursting oscillations : the role of slow variables

Mathieu Desroches

9/18/25, 2:15 PM

In this talk, I will present recent work on multiple-timescale dynamical systems displaying complex oscillations with both slow and fast components, with application to modeling neuronal activity. After a brief review of bursting oscillations and their multiple-timescale analysis, I will revisit the classical parabolic bursting scenario and show how to understand its spike-adding structure by...

6. A computational tissue repair model identifies an early transient decrease in fiber cross-linking that unlocks regeneration in adult mammals

In adult mammals, scar formation predominates over tissue regeneration, often leading to dysfunction due to the disrupted relationship between tissue architecture and function. Addressing this challenge is crucial in regenerative medicine. The restricted regenerative capacity in mammals suggests the presence of inhibitory factors established early in life. Our previous studies, using a model...
