extends the Hierarchical Temporal Memory model for intelligence in the Neocortex
Reference Frames
Spatial referencing
- based on evolved for function of locating yourself in space - Grid Neurons
- Neural Recycling – idea from How We Learn - Stanislas Dehaene
- could be multidimensional - abstract conceptual space
Sparse Representations - Sparsely Distributed Representations
Learning and Synaptogenesis
- Long Term memory needs new synapses created
- Short term memory using existing but inactive synapses in hippocampus - Silent synapses . they can flip quickly from inactive to active

Neurons / Synapses /
- Real Neurons - from 5 to 30000 synapses
- 5% of synapses are close by - can affect the soma the cell body
- 95% are distant
- Distant synapses when they fire create dendritic spikes . which raises voltage of the cell (potentiation but not enough to make neuron fire.
- instead, distant synaptic firings decreases current neuron’s firing time. which is important to beat inhibitory process from neighbouring reference frames. see Inhibitory Neurons
- the neuron is a predictive engine on its own
