Spreading Activation
- When neurons fire, they send information down the axons to the
synaptic cleft, and on to adjacent neurons.
- Earlier simulations had this.
- It increases connection weights

- Spread of activation also allows pattern completion effects.
- This in turn allows categorisation, by activating a group of
neurons.
- Whichever group is activated is the category with which the
pattern is associated
