Cell Assemblies

• Direction is drawn from Hebb's Cell Assembly (CA) hypothesis (1949).
• The neural representation of concepts is a recurrent network of neurons with a high amount of mutual synaptic strength.
• So, a symbol is stored in a CA.
• A network can have a lot of CAs.
• Hebb's learning rule allows for the formation (or learning) of CAs by mutual neural firing.
• If two neurons co-fire the strength between them tends to increase.
• This gives an explanation of both long and short term memory.
• This is incomplete though. There also needs to be process.
