Dr. Okray and Dr. Jacob: Combining colours and odours improved memory

In this episode, we're privileged to have an in-depth conversation with renowned researchers Dr. Pedro Jacob and Dr. Okray about their groundbreaking research on the fascinating world of multisensory integration and memory enhancement. This duo's cutting-edge study, conducted on the humble fruit fly, Drosophila, explores how associating multiple sensory cues with objects and experiences can dramatically improve object recognition and memory performance.Dr. Jacob and Dr. Okray delve into the mysterious neural mechanisms that are involved in binding sensory features during learning and how these mechanisms amplify memory expression. Their research uncovers a remarkable memory phenomenon, where combining colors and odors can enhance memory performance, even when each sensory modality is evaluated individually.Our experts also shed light on the pivotal role of mushroom body Kenyon cells (KCs), revealing that they are crucial for the improvement of both visual and olfactory memory after multisensory training. They further share their findings about how multisensory learning binds activity between modality-specific KCs, generating a multimodal neuronal response from unimodal sensory input.This engaging conversation goes on to explore the process of cross-modal binding, its role in expanding memory engrams, and how this broadening effect can improve memory performance post-multisensory learning. The researchers discuss their insights about how this process allows a single sensory feature to bring up the memory of a multimodal experience.Tune into this episode for a deep dive into the complex world of multisensory integration and memory, with insights that promise to reshape our understanding of learning and cognition.
