Being Human Now - Memory

Spark, With Nora Young, by CBC Radio explores how neuroscience and technology intersect to enhance our understanding of memory. Joshua Sariñana explains how memory engrams—networks of neurons encoding experiences—can be visualized and artificially activated using advanced techniques like optogenetics. The conversation delves into the subjective and malleable nature of memory, illustrating how cues such as photographs can aid memory recall or even implant false memories through imagination and suggestion. Sariñana reflects on how his work as a photographer enriches his personal memory, emphasizing the importance of visual stimuli as memory anchors. The discussion highlights how emerging technologies like optogenetics offer revolutionary insights into brain function and potential treatments for memory-related conditions, such as Alzheimer’s disease.
