Traveling Waves Integrate Spatial Information Through Time

Understand

Traveling waves of neural activity are widely observed in the brain, but their precise computational function remains unclear.

• One prominent hypothesis is that they enable the transfer and integration of spatial information across neural populations.
• However, few computational models have explored how traveling waves might be harnessed to perform such integrative processing.
• Drawing inspiration from the famous "Can one hear the shape of a drum?" problem -- which highlights how normal modes of wave dynamics encode geometric information -- we investigate whether similar principles can be leveraged in artificial neural networks.
