May-Britt Moser

life science Maturity 9-11 Next article →

May-Britt Moser is a prominent Norwegian neuroscientist and psychologist. She currently serves as a Professor of Psychology and Neuroscience at the Norwegian University of Science and Technology (NTNU). Her research focuses on how the brain represents space and navigation. This work is vital for understanding cognitive processes. It also helps scientists study neurological conditions like Alzheimer's disease. By understanding how the brain maps the world, researchers can better study spatial deficits in humans.

Her most famous work involves the brain's internal positioning system. She discovered specific cell types within a circuit in the entorhinal cortex. This area is located near the hippocampus, a region deep in the brain. The hippocampus is essential for episodic memory and encoding space. Moser identified grid cells, which are specialized neurons that help represent spatial locations. These cells work alongside other space-representing cells to create a mental map. This system allows an organism to understand its position in an environment.

The mechanism of spatial navigation relies on these neural circuits. The entorhinal cortex and the hippocampus work together through direct circuitry. Grid cells provide a framework for spatial representation. This allows the brain to track movement and location. Moser's research has explored how the anatomical structure of the hippocampus correlates with spatial learning. She specifically investigated these patterns in rats to understand the biological foundations. This research shows how physical brain structures enable complex behaviors like navigation.

Moser's journey began in the small Norwegian town of Fosnavåg. She was born in 1963 as the youngest of five children. Her father worked as a carpenter on a small family farm. As a child, she felt a strong passion for studying animals. She initially dreamed of becoming a veterinarian or a doctor. She attended the University of Oslo to study psychology, mathematics, and neurobiology. During her university years, she met Edvard I. Moser. They married in 1985 and became lifelong scientific collaborators.

Her academic career progressed through several significant stages. She earned her degree in psychology in 1990. In 1995, she obtained her Ph.D. in neurophysiology from the University of Oslo. Her thesis examined the hippocampus and spatial recognition in rats. After her doctorate, she completed postdoctoral training in the United Kingdom. She worked with Richard Morris at the University of Edinburgh. She also visited the laboratory of John O'Keefe at University College London. These experiences helped shape her expertise in neuroscience.

Moser has received many prestigious international honors for her contributions. In 2014, she shared the Nobel Prize in Physiology or Medicine. She received this prize alongside Edvard Moser and John O'Keefe. This award recognized their discovery of grid cells and spatial positioning. She is one of only six couples to ever win a Nobel Prize. In 2013, she also received the Madame Beyer award. This award honored her leadership, scientific success, and ethical standards.

Beyond her awards, Moser has built important research environments. She and Edvard Moser established the Moser research environment at NTNU. She helped found the Centre for the Biology of Memory in 2002. In 2007, she was involved in creating the Institute for Systems Neuroscience. She also served as the Founding Director of the Centre for Neural Computation. Since 2023, she has led the Centre for Algorithms in the Cortex. Her leadership continues to drive the study of complex brain functions.

Moser's work connects many different fields of science. Her research bridges psychology, neurobiology, and mathematics. By studying how cells code for position and velocity, she informs computational neuroscience. This field looks at how the brain processes information like a computer. Her findings help explain how the brain manages both space and memory. This connection is essential for understanding how humans interact with their physical world. Her legacy lives on through the many research centers she has helped build.
