When Cortical Neurons Talk Sideways: Beyond Feedforward Visual Processing

Tue, 11 Feb 2025 00:00:00 +0000

In this seminar we will challenge the traditional understanding of neuronal connectivity in primary visual cortex. While current theory suggests that neurons connect preferentially to others with similar orientation preferences, I will present evidence for a more complex connectivity pattern based on a distance-dependent rule: short-range connections show a like-to-like bias, while long-range connections connect more widely. This revised model better explains how the visual cortex processes complex stimuli and accounts for observed variations in neuronal interactions at different scales.

When: Wednesday 11th of February, 2025 from 14:30 to 16h30.
Where: room D2.2 of Collège de France
