Bio Neurons versus Computational

When we first learned of the use of the patterns of brain neurons to potentially use as reasoning devices, we took a course from actual neuroscientists.  We very quickly learned that human bio neurons were very much more complex that neurons in our feeble  'neural networks'.   Always been intrigued by the concept, so how could they be more useful 'reasoners"? Tried to augment  our nets with this new complexity.  Here is another case why they are very different.  We can ask ourselves, can we use these aspects of neurons to improve reasoning?  Note the indication that timing matters.  What embedded information  could make us learn faster?   Still unclear, 

Neurons Unexpectedly Encode Information in the Timing of Their Firing

A temporal pattern of activity observed in human brains for the first time may explain how we can learn so quickly.

For decades, neuroscientists have treated the brain somewhat like a Geiger counter: The rate at which neurons fire is taken as a measure of activity, just as a Geiger counter’s click rate indicates the strength of radiation. But new research suggests the brain may be more like a musical instrument. When you play the piano, how often you hit the keys matters, but the precise timing of the notes is also essential to the melody.

“It’s really important not just how many [neuron activations] occur, but when exactly they occur,” said Joshua Jacobs, a neuroscientist and biomedical engineer at Columbia University who reported new evidence for this claim last month in Cell.  ... '
