Conference paper


Recently, we found that some human hippocampal formation units fire specifically to particular words or faces. In this presentation, we will briefly describe this phenomenon (for further details, please see Heit et al., under revision). We then discuss the implications of this finding for how the brain encodes complex cognitive stimuli, and for the physiological mechanism whereby the hippocampus contributes to Recent Memory in humans.
