Size of Memory Objects

Abstract

I consider model for flares proposed by P.-G de Gennes (PNAS, 101 (44), 15778-15781, 2004) and suggest a range for amplification factor (I) for inhibitory neurons for the time evolution of non-divergent generations of excitatory neurons which eventually die out. The exact numerical solution of the model for the suggested range of the factor (I) then provides minimum number of neurons describing size (M) for memory objects. The obtained size is M = 8 to 12.75 and which is larger than the size M = 2 to 4 as obtained theoretically by de Gennes.
