EXPONENTIAL JUMP. “This state is achieved due to the following effect. A high excitation level of some neurons – due to their negative synaptic connections with others – lowers to zero the excitation threshold energies for the latter neurons, thereby making is possible to store an exponentially large number of patterns within an infinitesimally narrow energy gap. Moreover, the patterns stored in such states can be redialed under an influence of arbitrarily soft external stimuli.”
