Selective inhibition in CA3: A mechanism for stable pattern completion through heterosynaptic plasticity
Fig 10
Effect of engram size in CA3 on retrieval.
(A) Cue schematic: two CA3 engrams of different sizes are cued. (B) Example learned Rc weight matrix. (C) CA3 engram firing rates for example trials with the same cue: (C1) memory A is retrieved, (C2) memory B is retrieved. (D) Retrieval performance versus engram size differences, comparing conditions with (blue) and without (red) selective inhibition. (E) Dominance of the larger engram: fraction of successful trials retrieving the larger-memory engram, versus size differences, comparing with (blue) and without (red) selective inhibition.
