In the third episode of Season 2 of the B5Y Podcast, we continue exploring Dr. Marvin Weigand’s PhD thesis, diving into the second paper: "Neural Placement Based on Optimization Principles." This episode focuses on how hypercolumns, the foundational units of the visual cortex, are remarkably consistent in size across different species, despite varying brain sizes.

Key topics include:

• The structure of hypercolumns in the visual cortex and their role in processing visual information.
• How a fixed number of neurons within hypercolumns contributes to efficient visual processing across species, from mice to elephants.
• A novel computational model that explains how neurons organize themselves based on communication needs, leading to the formation of hypercolumns and pinwheel structures.
• The implications of this model for understanding brain efficiency and how these principles may apply to other parts of the brain and even to AI systems.
