Cell Assemblies
- Cell Assemblies (CAs) are recurrent networks of neurons that represent
(among other things) concepts in the brain.
- It is well known that CAs account for short and long term memories:
the dual trace concept.
- However, to do this they must also have parallel dual stable states.
- Short term stable states are relatively well understood and
are accounted for by similar sets of neurons firing.
- Long term stable states are less well understood.
- One of the problems is that the brain needs to modify old concepts
to form new ones.
- Today, I will describe some problems and will propose
some possible solutions.
- We will also have a look at what a theory of CAs should
do.
