A place for maps in the human brain

Figure Nobel Prize in Physiology or Medicine 2014

Figure by Mattias Karlén

The 2014 Nobel Prize in Physiology or Medicine honors the discoveries of cells that constitute a positioning system in the brain. These efforts are crucial for many research agendas in the cartographic community concerned with cognitive processes and impact-oriented maps.

Recent investigations with brain imaging techniques, as well as studies of patients undergoing neurosurgery, have provided evidence that place and grid cells exist also in humans. In patients with Alzheimer’s disease, the hippocampus and entorhinal cortex are frequently affected at an early stage, and these individuals often lose their way and cannot recognize the environment. Knowledge about the brain’s positioning system may, therefore, help us understand the mechanism underpinning the devastating spatial memory loss that affects people with this disease.

The discovery of the brain’s positioning system represents a paradigm shift in our understanding of how ensembles of specialized cells work together to execute higher cognitive functions. It has opened new avenues for understanding other cognitive processes, such as memory, thinking and planning.
