The Role of the Fimbria Fornix in Spatial Navigation

The Role of the Fimbria Fornix in Spatial Navigation

Researchers from UCN are currently trying to uncover the role of the fimbria fornix (an accumulation of myelinated axons beginning at the ventral part of the hippocampus) in long term memory storage and spatial navigation. Although it has long been known that the hippocampus is involved in memory and spatial navigation research has mainly focused on what is known as allocentric navigation which can be thought of as a type of “map-based” navigational strategy in which orientation is based on cues that are external to the navigational task. One example of this would be using your iphone to find your way around the city. In contrast to allocentric strategies another way to find your way around is simply remember the different sequences of left and right turns that has previously gotten you from A to B. This is known as senquential egocentric navigation and it is this type of navigational strategy that researchers at UCN are particularly interested in and which they suspect is affected by damage to the fimbria fornix….
