By contrast, the first half of each theta cycle is devoted to comput-ing current position using sensory information from the lateral entorhinal cortex(LEC) and path integration information from the medial entorhinal cortex (MEC).This model explains why MEC lesions can abolish hippocampal phase preces-sion but not place fields.
