Fly brains store and process memories through complex neural circuits that involve the formation, consolidation, and retrieval of memory traces. These processes are similar to those found in mammalian brains, suggesting a common evolutionary origin.
4.1. Memory Trace Formation
When a fly encounters a new experience, a memory trace is formed in its brain. This trace is a physical representation of the experience, encoded in the connections between neurons. The researchers observed the formation of memory traces in fruit flies’ brains using real-time calcium activity tracking.
4.2. Consolidation of Memories
Over time, the memory trace is consolidated, becoming more stable and resistant to disruption. This process involves the strengthening of the connections between neurons in the memory circuit.
4.3. Retrieval of Memories
When a fly needs to recall a memory, the memory trace is retrieved from storage. This involves reactivating the neurons in the memory circuit, allowing the fly to access the information encoded in the trace.
4.4. Brain Regions Involved in Memory
Specific brain regions are responsible for forming memories such as the mushroom body, a structure involved in learning and memory. Calcium activity tracking has allowed researchers to record the formation and duration of the flies’ memories, offering valuable insights into insect neurobiology.
5. What Is the Significance of Finding Similar Cognitive Functions in Flies and Mammals?
