- spatial analysis showed that one third of the newly formed synapses were located next to another new synapse. The new synapses were formed over several days
- second connections which formed from repetitive activation strengthened the first connection - this clustering may "magnify the strength of the connections"
- when learning two different tasks new synapses were formed but they did not cluster together
