A study demonstrates the learning and attention capacity of Drosophila, paving the way for a potential model for cognitive science research.
Drosophila are small flies that are widely used as an animal model in scientific research, especially in the field of genetics. But a study published recently in the journal Nature revealed the underestimated cognitive abilities of Drosophila. The authors of the article suggest that Drosophila can be considered as a potential model for research into higher cognitive functions.
The scientists used a virtual reality environment to test the flies' learning and attention capabilities and to observe the formation and disappearance of a short-term memory trace in the insects. Despite the considerable anatomical difference, these functions, often only attributed to mammals, seem to be present in Drosophila. This similarity makes Drosophila an animal of interest for cognitive science research.
