In What Sense, if Any, do Hippocampal “Time Cells” Represent or Encode Time?

• The first part of this poster is a conceptual discussion of the notion of a time cell. It is argued that some neural structures must encode time in a more fundamental way than the time cells do. I introduce the term “i-timecode” for this fundamental representation. The second part places the conceptual discussion in a context of certain wellknown empirical findings in humans. The third and last part presents two main alternative approaches when formulating a theory of the i-timecode. These are: mapping time to space, and transforming time to the frequency domain (or a mixed domain). I also present a version, in gross outlines, of the second approach. In it, neural oscillations are given a role that is quite different from those which they, in the contemporary discussion of time cells in the hippocampus, have been hypothesized to play.
