Abstract
The invention provides for the use of synaptic strengths to reflect the connectivity of local space to give a topological representation. Synaptic strengths are zeroed and the mobile entity's position is initialized. A probability of firing (P) is calculated from the spatial firing pattern of each cell. A cell fires if P is higher than a random number. The mobile entity's position is updated from a record of real motions and firing is again determined. Synapses between cells that both fire within 250 msec are strengthened. Synapses between cells with overlapping fields increase in strength whereas synapses between cells with distant fields will stay weak.
