HTM is intended to be a theory of the neocortex. But in some ways the algorithm seems to apply more appropriately to the hippocampus. In particular, both HTM and the hippocampus learn from experience online, and very qui…

I have been thinking about this for awhile. It seems the the trisynaptic circuit of the hippocampus is a perfect way to encode time/rythm to integrate with other information. It has been discussed before that simple repr…

"In this work, we show that transformers, when equipped with recurrent position encodings, replicate the precisely tuned spatial representations of the hippocampal formation; most notably place and grid cells. In this…

Are place cells just memory cells? Memory compression leads to spatial tuning and history dependence Abstract The observation of place cells has suggested that the hippocampus plays a special role in encoding spatial in…
