Precise positional modulation was not observed more ventromedially in the entorhinal cortex or upstream in the postrhinal cortex, suggesting that sensory input is transformed into durable allocentric
spatial representations internally in the dorsocaudal medial entorhinal cortex.
It not only confirms that cockroaches have access to
spatial representations of their own inner worlds, but it also suggests that they can
internally build a
spatial representation of the surrounding olfactory landscape.
