It’s good to study the piriform cortex to understand memory formation / neuroplasticity, as (IIRC) it’s one of the most primitive “plastic” parts of the brain.

It’s good to study the piriform cortex to understand memory formation / neuroplasticity, as (IIRC) it’s one of the most primitive “plastic” parts of the brain. In some species (e.g. fruit flies) the piriform cortex is the only part of the brain that changes at all after birth; i.e. it’s the only place where learning could possibly be going on. So, even if the it’s not intimately linked with human memory, the piriform cortex may be the origin of the cellular template that later diverged into whichever other brain tissues are responsible for other types of memory.
