Towards understanding the neural basis of spatial navigation
Prof. Dr. Andreas Herz (LMU München)
Remembering paths through an environment relies on specialized neural circuits. Here, "place cells" discharge when the animal is at a certain location, whereas the multiple firing fields of a "grid cell" form a hexagonal lattice. I will show that in both systems, spatial location is encoded not only in whether a cell fires or not, but also in the relative timing of action potentials and discuss why it is highly advantageous to complement a place code with a second, grid-like code.
