Neuropeptide-mediated temporal sensory filtering in a primordial nervous system.

Unlabelled: Sensory filtering - prioritizing relevant stimuli while ignoring irrelevant ones - is crucial for animals to adapt and survive in complex environments. While this phenomenon has been primarily studied in organisms with complex nervous systems, it remains unclear whether simpler organisms also possess such capabilities. Here, we studied temporal information processing in , a freshwater planarian flatworm with a primitive nervous system.
