MARIANNE FYHN: WHAT EXACTLY ARE MEMORIES?| SCIENCE NEWS
And how do experiences modify the circuits of the brain to form them?
This is the focus of the research conducted by Marianne Fyhn. She is an associate professor at the University of Oslo, where she runs the Centre for Integrative Neuroplasticity (CINPLA).
“In my research I want to identify the neural fingerprint that reflects learning of sensory experiences…” she says. To achieve this she uses large-scale recordings of neurons and transcranial two photon laser scanning microscopy (2PLSM) to identify changes in the brain. It’s neuroscience!
And in the world of neuroscience, Marianne is truly working at the cutting edge. As a graduate research fellow, she assisted the work of May-Britt and Edvard Moser at NTNU, doing research on memory and the brain’s ability to navigate. In 2004 she published an article in Science describing how certain cells in the brain form a mental map of its surroundings. A year later, she published an article in Nature, where she named these cells “grid-cells”. She based her thesis on this work, and her PhD was elected the world’s best in Neuroscience for 2005. Since then her research has continued to provide ground-breaking results and win prestigious awards. The finding of the grid-cells led to the award of the Nobel Prize in Physiology or Medicine 2014, won by May-Britt and Edvard Moser.
Today Marianne Fyhn relentlessly continues her pioneering work to unravel the mysteries of the brain. If you want insight into how the brain works and how scientists are exploring it, watch the talk from Cutting Edge festival 2015 below!
