  We derive the Gardner storage capacity for associative networks of threshold linear units, and show that with Hebbian learning they can operate closer to such Gardner bound than binary networks, and even surpass it. This is largely achieved through a sparsification of the retrieved patterns, which we analyze for theoretical and empirical distributions of activity. As reaching the optimal capacity via non-local learning rules like back-propagation requires slow and neurally implausible training procedures, our results indicate that one-shot self-organized Hebbian learning can be just as efficient.

  The contribution of hippocampal circuits to high-capacity episodic memory is often attributed to the large number of orthogonal activity patterns that may be stored in these networks. When rodents explore an environment for the first time, a new combination of active place cells is recruited which appears different from maps of already familiar environments. The orthogonality of the representations is thought to minimize interference between memories for experiences with overlapping spatial elements and to allow large numbers of experiences to be stored in the same network. This view is challenged, however, by the recent observation that firing patterns in a novel environment correlate with activity patterns recorded in the resting state before the animal entered the environment for the first time (Dragoi and Tonegawa, 2011). Instead the presence of experience-independent firing sequences points to the hippocampus as a preconfigured network from which sequence information is recruited repeatedly across environments and experiences (McNaughton et al., 1996). To test this possibility, we measured the relatedness of hippocampal representations in 10 sequentially presented test rooms, allowing for 45 map comparisons - many more than in any previous work. Five new environments were presented on each of 2 consecutive days. A familiar room was presented at the beginning and the end of each experimental day to test for stability. On each trial, activity was recorded from large ensembles of neurons in hippocampal area CA3, with an average of approximately 30 active cells per trial. Population vectors were defined to correlate cell populations within and across all 11 rooms (novel and familiar). Representations were highly correlated between repeated tests in the same room but nearly orthogonal across all combinations of different rooms, indicating that unique representations were initially expressed in each environment, despite the similarity of the rooms. The results suggest that the mnemonic capacity of the hippocampal CA3 spatial-mapping network is large, with minimal recurrence of firing patterns across environments.
