Researchers Investigate The Brain’s ‘GPS System’
The study looked at how the rhythmic activity of neurons supports spatial navigation.
Professor Dr. Motoharu Yoshida and fellow research scientists from Boston University have discovered that nerve cells in the entorhinal cortex (which is important for spatial navigation) oscillate with individual frequencies, which depend on their position within the cortex. This rythmic activity suggests a kind of GPS system in the brain and the activity of individual neurons in this brain region represents different positions in space.
This study was the focus of Frequency of Subthreshold Oscillations at Different Membrane Potential Voltages in Neurons at Different Anatomical Positions on the Dorsoventral Axis in the Rat Medial Entorhinal Cortex, an article recently published in The Journal of Neuroscience. Yoshida explains:
