Q

What is the fornix?

A

a major fiber bundle that connects the hippocampal formation to the mammillary complex of the hypothalamus.

17
Q

Where is the hippocampus?

A

the medial temporal lobe, embedded within special cortex termed entorhinal cortex

18
Q

What is the path that information flows through the hippocampus?

A

EC to CA3 via perforant pathway; CA3 to CA1 via Schaffer collaterals, then out to the subiculum.

19
Q

Where are long-term or declarative memories stored/

A

Neocortex
