Hot Coffee: Associative Memory with Bump Attractor Cell Assemblies of Spiking Neurons Networks of spiking neurons can have persistently firing stable bump attractors, to represent large number spaces (like temperature). This can be done with a topology that has local excitatory synapses, with surround inhibition, but with any particular topology there are critical points in the weight space. Activating large ranges in the bump can lead to streams, that show repeller attractor dynamics. These streams can be merged by overcoming these repeller dynamics. A simple associative memory can include these bump attractors, allowing the use of continous variables in these memories. This is a step toward a more complete cognitive associative memory.
