When the hippocampus recalls a past location, it retrieves
the stored spatial memory from a subregion of the hippocampus called CA3.
The posterior hippocampus
stores spatial memory.
The neurons in the hippocampus that
store spatial memories (such as the location where you parked your car) are called place cells.
Bees don't have the brain structure, called the hippocampus, thought to
store the spatial memories underlying mental maps in humans.

According to Baddeley and Hitch's model, we
store and alter
memories through a phonological loop, which processes sound information, and through a visuospatial scratchpad, which maintains and manipulates
spatial and visual information.
This brain region plays a critical role in learning new information, forming
spatial memories and
storing short - term
memories as long - term ones.
And because these robins
store food for the winter, the scientists also measured their
spatial memories.
«We already knew that newly acquired information is
stored into different types of
memories,
spatial or emotional, before being consolidated or integrated,» says Sylvain Williams, a researcher and professor of psychiatry at McGill.
By asking participants to recall the items they delivered instead of the
stores they visited, the researchers could test whether their
spatial memory systems were being activated even when episodic
memories were being accessed.
This allowed the researchers to correlate the neural activation associated with the formation of
spatial memories (the locations of the
stores) and the recall of episodic
memories: (the list of items that had been delivered).
As participants passed by a particular
store, the researchers correlated their
spatial memory of that location with the pattern of place cell activation recorded.
To avoid confounding the episodic
memories of the items delivered with the
spatial memory of a
store's location, the researchers excluded trips that were directly to or from that
store when placing it on the neural map.
Research suggests that some of the brain regions responsible for forming and
storing memory of past events, such as the hippocampus and the entorhinal cortex, are the same ones responsible for
spatial navigation, implying a deep connection between the two processes.
