Summary
The ability to associate some stimuli while differentiat-
ing between others is an essential characteristic of
biological memory. Theoretical models identify mem-
ories as attractors of neural network activity, with
learning based on Hebb-like synaptic modifications.
Our analysis shows that when network inputs are
