Editing Place cell (section)

=== Relationship to grid cells ===
It has been proposed that place cells are derivatives of [[grid cell]]s, pyramidal cells in the entorhinal cortex. This theory suggests that the place fields of the place cells are a combination of several grid cells, which have hexagonal grid-like patterns of activity. The theory has been supported by computational models. The relation may arise through [[Hebbian theory|Hebbian learning]].<ref name="Moser-2008">{{Cite journal |last1=Moser |first1=Edvard I.|last2=Kropff |first2=Emilio |last3=Moser |first3=May-Britt |date=2008 |title=Place Cells, Grid Cells, and the Brain's Spatial Representation System |journal=Annual Review of Neuroscience |volume=31 |issue=1 |pages=69–89 |doi=10.1146/annurev.neuro.31.061307.090723|pmid=18284371 |s2cid=16036900}}</ref> But grid cells may perform a more supporting role in the formation of place fields, such as path integration input.<ref>{{Cite journal |last1=Bush |first1=Daniel |last2=Barry |first2=Caswell |last3=Burgess |first3=Neil |date=2014-03-01|title=What do grid cells contribute to place cell firing? |journal=Trends in Neurosciences |volume=37 |issue=3 |pages=136–145 |doi=10.1016/j.tins.2013.12.003 |pmid=24485517 |pmc=3945817 |issn=0166-2236}}</ref>
Another non-spatial explanation of hippocampal function suggests that the hippocampus performs clustering of inputs to produce representations of the current context – spatial or non-spatial.<ref>{{Cite journal |last1=Mok |first1=Robert M. |last2=Love |first2=Bradley C. |date=2019-12-12 |title=A non-spatial account of place and grid cells based on clustering models of concept learning |journal=Nature Communications |volume=10|issue=1|pages=5685 |doi=10.1038/s41467-019-13760-8 |pmid=31831749 |pmc=6908717 |bibcode=2019NatCo..10.5685M |issn=2041-1723}}</ref>
