Cell Assembly Background
- Hebb initially proposed Cell Assemblies (CAs) in 1949.
- Concepts, and other things, are represented in the brain
by reverberating circuits of neurons.
- The circuit is formed via unsupervised learning
from environmental stimuli.
- This model has a lot of benefits including
the ability to represent short and long-term memories.
- There is extensive physiological and psychological evidence that
CAs are in the brain.
- There have been computational models since the 50s (e.g. Rochester
et. al).
- Existing models of CAs do not really do much with each model
usually doing a single task.
- There is not a good understanding of how neurons work together
for the many tasks they must do.
